Latest / The Shed Organics Show / #48 - Can Hydroponics Save Our Food Crisis? | Bohdi Gardener [Fran's Hydroponics]
Transcript
- 0:00Hey everybody, welcome back to another episode of The Shed
- 0:03Organics Show. Today's guest we have Bodie from
- 0:08Friends Hydroponics here in Brisbane, a hydroponics store
- 0:13helping people grow hydroponically.
- 0:15Would you believe? Now, I don't often speak about
- 0:19this growing method. Obviously you'll know that I'm
- 0:22very big on organic living soil. That's my thing.
- 0:25But that doesn't necessarily mean that there's not a place
- 0:28for other methods of growing. And whether or not hydroponic
- 0:32aquaponics or all of these different things can match soil
- 0:36growing or outdoor soil growing, then, you know, it's really
- 0:40interesting to test these different methods and see
- 0:42whether there's a place for them.
- 0:44And whether or not we can actually improve the
- 0:46technologies used in these systems to greatly match the sun
- 0:50and things like that, that we speak about today in the
- 0:52conversation. And the nutrient availability,
- 0:55the the cost and the water saving and all of this so, so
- 0:59many things that we touched on today in terms of hydroponic
- 1:02growing and its place in the world and how so many people are
- 1:06using this way of growing to access homegrown food.
- 1:10If they're in an apartment or they don't have enough light or
- 1:13all sorts of different things, they can grow their own food at
- 1:16home. So Bodie takes us through a
- 1:19whole bunch to do with hydroponic growing.
- 1:22And if this is something that you've ever considered or you
- 1:25want to know what the difference is between hydroponics and our
- 1:28standard living soil growing, then this conversation is for
- 1:33you. So stick around Here is Bodie
- 1:36from Friends Hydroponics. So yeah, the people we get
- 1:56through, it's a bit of a specialty store, so it's not
- 1:59like going to Bunnings where you're kind of looking at
- 2:02everything. People usually have an idea of
- 2:04what they're coming in for. They've searched for something
- 2:06and they've found us and they come in, we're kind of known a
- 2:10little bit for our customer service.
- 2:11So when they come in, we don't tend to let people drift.
- 2:13I, we're more than happy to let them.
- 2:15We want them to look around. We'll encourage it.
- 2:17But usually like is, you know, are you already doing something
- 2:20or did you want help finding something or is there something
- 2:23you're thinking about? Because the, I love gardening in
- 2:27general and horticulture in general in all its aspects.
- 2:31The reason I sort of ended up in hydroponics is because it's,
- 2:35there's so many parts to it and I've seen people do things that
- 2:39you literally like, I have no idea where that came from or how
- 2:44that works, but it does. And it's just so kind of
- 2:47intricate and so many ways you can do things.
- 2:51But the people that come in, we have a whole range of different
- 2:55growers. We, we had a boom of home
- 2:56growers during the food because the prices of food have gone up.
- 3:01The good thing about hydroponics is that it really lends itself
- 3:05to people who aren't in the position to have soil like
- 3:09apartment people, people with small spaces, balconies, flats,
- 3:13rental places that you can't commit to a long term garden
- 3:16where you really have to look after the soil for long periods
- 3:19of time and seasons. It's more of a pop up, instant
- 3:22kind of thing. So I guess that's kind of the
- 3:24one of the advantages of it. I know you can pop up a pot of
- 3:28soil, but then moving the soil again or you know, you, you know
- 3:35that the best from soil is when you really have time to, to care
- 3:39for it long term and not just throw a mix into a pot and go
- 3:42from there. So it, so we have those growers,
- 3:46but we also have like professional, what do you call
- 3:51like rare indoor plant growers, specialty plant growers, like
- 3:54orchid growers, you know, people who buy $5000 cuttings from
- 4:00Monsterias first in the country and try to propagate and change
- 4:04those. Because we kind of have the
- 4:10basic specialty mediums for those plants and also specialty
- 4:15nutrients for those plants as well.
- 4:17It's a, it's very direct and they know exactly what they're
- 4:19feeding. So we have a whole range of
- 4:23growers and you know, you get all kinds of types that you
- 4:26never, sometimes you never know really what people are doing,
- 4:28but you do your best to accommodate and just help people
- 4:32with their problems. So.
- 4:34Yeah, very true, man. That gives me a good overview in
- 4:36terms of like the types of people coming through.
- 4:39It's like it seems to me that you know, you've got one end of
- 4:43the stick where you say you've got experienced people that are
- 4:46looking for something very specific often where they can
- 4:50control the amount of light, humidity, all of these types of
- 4:54things, even temperature and all of that going so far CO2.
- 4:58So you can really nerd out on trying to really control the
- 5:02climate in certain indoor. Spaces.
- 5:05No, it's too far. I bet.
- 5:08Yeah, exactly. But then, yeah, on the other end
- 5:11of the stick, you've got people who are just generally
- 5:14interested in trying to grow some something for themselves,
- 5:17but they can't access to soil and things like that.
- 5:20I want to touch into the difference between what
- 5:24hydroponics is compared to soil, because obviously you, like you
- 5:28said, you can use soil in these instances where you're growing
- 5:32indoors or you're growing under an artificial setup or something
- 5:35like this. But talk to me about hydroponics
- 5:38itself as a practice. What actually is it if you have
- 5:41to run it down into a basic thing, and what sort of things
- 5:45are people growing hydroponically?
- 5:47Does it lend itself to certain plants more than others, or is
- 5:50it just generally everything fits?
- 5:54That's a good question. So well basically hydroponics is
- 5:59when your nutrient need needs for the plant are entirely met
- 6:04through your watering system. So that can even just mean hand
- 6:08watering. If your medium that you're
- 6:12growing your plant in contains plant alcohol, the roots and the
- 6:16growth of the roots, then hydroponics is just everything
- 6:19that plant that you need to feed, while all the nutrition
- 6:22that it requires to grow comes from the water that you feed it.
- 6:25So that's basically the the pure deaf and basic definition where
- 6:30your soil support would just contain everything and you would
- 6:34just make sure that everything is there so that you don't have
- 6:36to think about it and the plant just can take what it needs.
- 6:40So yeah, it is a lot more specific pretty well from what
- 6:44I've seen now. Like originally I thought it was
- 6:47quite, I guess, like most people that it was quite specific.
- 6:49You know, you always see the same examples of his tomatoes,
- 6:53his cucumbers, his lettuce, you know, his amazing greens.
- 6:59You know, of course, you know, medical cannabis is, or cannabis
- 7:02in general in the world has always.
- 7:03When you hear hydroponics, people still that's the first
- 7:05thing they think regardless, even though like maybe 80 or
- 7:10more percent of your cals in Woolworths crops are actually
- 7:14all grown in hydroponics, people still immediately think of
- 7:16cannabis, but at least most of the leafy greens and greens that
- 7:22they buy. But yeah, so it's amazing.
- 7:26I've seen literally everything grown in hydroponics that you
- 7:29can grow in the soil with maybe some very rare cases for very
- 7:34particular plants that it just wouldn't be viable or make any
- 7:38sense to do so. Like but you know you can grow
- 7:42root vegetables fine as long as you get a good substrate.
- 7:45Although they will use aeroponics which is similar
- 7:48where they'll miss the roots and I've seen them grow potatoes
- 7:52that way and just hanging free hanging you can.
- 7:56You generally don't see people grow larger things with a big
- 8:02central root system like a big tap root system in hydroponics
- 8:05is often because there's not as much depth.
- 8:08But it is a long term thing to be growing indoor orchards,
- 8:13especially in colder countries in the cold seasons indoors in
- 8:18hydroponics like bananas in huge hundred 200 litre hydroponic
- 8:22pots or orange tree crops. Or you know, it's very common to
- 8:27do raspberries, blueberries, things like that in very highly
- 8:32constructed Coco will pee substrate systems for about two
- 8:37years at a time. So you can practically grow
- 8:41nearly anything in hydroponics because as long as you're
- 8:44supporting the environment and the root system in the way that
- 8:49that plant desires and you're delivering the nutrients that it
- 8:52requires, then there's no reason for it not to grow.
- 8:57So it's amazing how adaptable it is.
- 9:00Yeah, it's really good, really interesting.
- 9:03Yeah, yeah, Yeah, it would be because I mean like as you say,
- 9:07you're trying to match the nutrient profile exactly what it
- 9:10needs and when it needs it. I imagine though, like the
- 9:15argument that I hear between soil and hydro, for example, is
- 9:20that as you mentioned earlier, with the soil, you can kind of
- 9:24load up a little bit, put some compost in things like this.
- 9:27And then it's sort of got this battery or buffet that the plant
- 9:30can access. And it's got the hopefully got
- 9:32the life in it, the living parts of the soil that can break down
- 9:36the amendments and the compost and turn it into plant available
- 9:39nutrients. But in this hydro, obviously
- 9:41it's directly plant available straight away because it's in
- 9:45solution, right? Is it super variable based on
- 9:50the plant as to what nutrients you're feeding it and when and
- 9:55how difficult is that to learn or teach somebody?
- 9:57We do get, we do constantly talk to people about this.
- 10:00So every plant is very different in terms of generally growing in
- 10:06hydroponics, like your consumer level hydroponics, the solutions
- 10:12that you would buy your base nutrient is usually a a general
- 10:17complex that's kind of matches most fast growing plants.
- 10:22Say, you know, something sort of like a tomato plant where you
- 10:26have a growth in bloom period. It'll cover a basically a base.
- 10:31It's not going to cover everything to the need of that
- 10:33plant. And of course it's very genetic
- 10:35specific too. So you can't really have a
- 10:38silver bullet. So a lot of the time there is
- 10:42lots of additives and people think it's a like selling snake
- 10:48oil. It's usually like they're
- 10:51specific for different areas of growth that you may not match
- 10:54with your base nutrient because you don't have a battery, you
- 10:57don't have this huge complex that's sitting there that's
- 11:01going to break down and the plants going to take it as it
- 11:03needs it. The, the salts that the nutrient
- 11:08salts that people refer to as chemicals, they, like you said,
- 11:13they're the available form that you plant takes up in the soil
- 11:16anyway, but they're already available.
- 11:18You don't have to break it down from compost.
- 11:21And the other issue is that because of that, it's immediate.
- 11:26So it's another reason why you don't really put these nutrients
- 11:32into soil because it it conflicts in a lot of ways.
- 11:36But yeah, you really, you really have to hit your targets on some
- 11:40different plants and needs. You would.
- 11:43And I also imagine, like you said, you're just kind of giving
- 11:47them the base of what they need. I want to talk about like the
- 11:51quality of the nutrient itself, like the different nutrient
- 11:55bottles that you can buy from different companies.
- 11:57How? How can someone still be, say,
- 12:02like organic? Is there a way of being organic
- 12:06in hydro? What does that mean to you?
- 12:09And how do you explain the difference between whether
- 12:11something is synthetically derived or organically derived
- 12:15in terms of the bottled nutrients?
- 12:18Yeah. And that that is a big industry
- 12:23like question and debate because there's so many different fields
- 12:26of like, you know, especially the, the terminology mostly
- 12:31around what organic really stands for.
- 12:33Like it doesn't have a carbon backbone.
- 12:35Like is it like, you know, does it, is it, you know, it's
- 12:39something that's pulled directly out of the ground but not
- 12:41processed? Is it synthetic?
- 12:44It, you know, it's mined, but is it's mineral, but is it not
- 12:47organic? Like it's there's this whole
- 12:50argument that goes on, but basically we generally tend to
- 12:54if it's a pure mineral salt, where there's no, I suppose you
- 12:59would say like, and you generally say if there's no
- 13:03organic components, acids, fulvic acids, humic acids,
- 13:07kelps, you know, compost teas, fish emulsion, vermicat, stuff
- 13:14like that. If there's none of that in there
- 13:16and it's just water and pure nutrient salts, we'd refer to
- 13:19that as mineral and non organic growing.
- 13:24But in the, in the last like, and it's even been longer, but
- 13:28let's say the last five years, there's been a huge progression
- 13:32towards and even on a commercial level, people wanting to go more
- 13:36organic with this process. And so sort of crossover
- 13:40nutrients, your Singanex, we like to, you know, to say is,
- 13:47you know, there'll be a combination, there'll be some
- 13:48minerals, salts in there to hit your targets, but then they will
- 13:51also include, so I guess you quality enhancing organics.
- 13:55So they'll put in some of those extra things.
- 13:58Cool a kelp, A kelp or seaweed or the the folic acids or any of
- 14:04those complex carbohydrates, things like that, They tend not
- 14:07to run as clean in the systems, but that's where the crossover
- 14:11is being difficult. And we're just sort of starting
- 14:14to see some purely organic products that run clean, which
- 14:19are huge advancement. But in saying that, you can
- 14:23also, if you want to run a hybrid system, you can also
- 14:28fortify the actual medium you're growing in.
- 14:30If you're using like a peat or a cocoa substrate, it's really
- 14:34easy to sort of fortify it with a lot of organic amendments.
- 14:38And so that way you're kind of like, you know, getting your
- 14:43regular on target feeds with the nutrients, but you're also
- 14:47getting some of these other components that benefit your
- 14:49bricks levels and your overall plant stress health and your
- 14:53beneficial microbes, which I know we talked about a lot, But
- 15:00so that's one way. And and there are systems that
- 15:03run usually more commercially that are nearly entirely water
- 15:10based, but organic. And they will do mixtures of
- 15:15teas, feed through lines into a neutral substrate like you would
- 15:19any, any hydroponics, but they're fully organic feeds.
- 15:26But then the difficulty for them is to continuously be flushing,
- 15:32cleaning lines, making sure that they're not getting blockages
- 15:36and other expensive equipment. Yeah, yeah.
- 15:38So yes, you can. You can in many ways kind of
- 15:41bridge the gap or get fully over there.
- 15:43That's cool. One thing that you just
- 15:47mentioned about is microbes or like any kind of sort of
- 15:52enzymes, things like this. I forgot enzymes.
- 15:56Yeah, Yeah, that's OK. In in aquaponics where we've got
- 16:00the combination of fish and in sort of aquatic plants and that
- 16:06providing some sort of nutrition.
- 16:08They're also cleaning it as well.
- 16:10I've seen that that can kind of have this nice cycle with
- 16:13aquaponics. But that's a lot to set up for
- 16:15your average grower when it comes to like plant nutrition,
- 16:20the actual plant itself, the quality of the plant at the end
- 16:23of the day, hydroponic versus soil growing, if they've got all
- 16:27the nutrients that they require, both of those, what's the
- 16:31difference between 1:00 that's grown in a living soil that's
- 16:34full of, you know, life in the soil versus one that's a soil
- 16:38less medium and it's water and stuff.
- 16:40Is there any difference in nutritional quality that you
- 16:44found or heard about in the end result between hydroponic grown
- 16:49food and soil grain? Yeah, absolutely.
- 16:53So look, I, I first want to say that, you know, we're France
- 16:58hydroponics, but really we're more about protective cropping.
- 17:04That's more of a commercial term.
- 17:05But anything that is like we do a lot of work with indoor stuff
- 17:10obviously and people doing stuff, intense artificial
- 17:13lighting environments. So we have a lot of organics and
- 17:17living soil and things in our store as well.
- 17:19So it's not purely hydro and I am a huge advocate and was
- 17:23before hydroponics about organic growing.
- 17:26And I think we can sustainably and economically do it on large
- 17:31scale. I think that that that's the
- 17:32better we should be sort of aiming down that road because
- 17:34it's working in in with the planet.
- 17:37And I think at the end of the day, I think it isn't like soil.
- 17:42People make soil to be easy, but it's it's it's very complex and
- 17:48if you're trying to get the very high standards that some
- 17:50industries are, it's you almost have to be like a full blown
- 17:55scientist to understand exactly what you're putting in and
- 17:58getting out. So it's a long road to get sort
- 18:02of to there. And I, I do want to see
- 18:04everything eventually get there, but hard to phonic, I think will
- 18:07have its place. But in terms of the nutrient
- 18:10difference, all your store bought crops, commercial big,
- 18:16you know, lettuce farms, things like this that are pumping out
- 18:18millions of lettuce. They have like literally
- 18:23millions of holes. Like I went to a lettuce farm
- 18:26that was local the other day, little farm, half a million
- 18:30holes of lettuce. What they're feeding is quite a
- 18:35simple nutrient routine. You know it, it's all about
- 18:39economics. You know, the more they put in,
- 18:41the more it's going to cost you in the store.
- 18:42So for them it has to be viable. For everyone else, it has to be
- 18:46viable. So I'd say that anything that
- 18:49you're getting in that circumstance, I think if you
- 18:51tested it, you're going to see fairly low levels of bio
- 18:54activity, especially with the treatments that they go through
- 18:57before getting to the stores. And also the nutrient inputs
- 19:00were very lean. So you're not going to have a
- 19:03huge build up in there, but the same applies to broad acre crops
- 19:09in soil that are also in big box stores because again, basically
- 19:14a very similar thing where they're they're they're in soil,
- 19:17but they're basically just spraying them with chemicals
- 19:19anyway. So you're still going to get a
- 19:21very similar thing now as you would understand like growing in
- 19:25a proper living soil ecosystem or a permacultural system.
- 19:29The nutrition of that is going to be off the charts compared to
- 19:32something else. And in terms of hydroponics, you
- 19:34can do something very similar. And I have seen a fair, a few
- 19:39white papers that have done the testing around it, but you got
- 19:42to put the inputs in and that's going to bring the price of the
- 19:45product up again. So it can be done.
- 19:49But I think ultimately I, I still think if you're going to
- 19:54talk about ultimate perfection of nutrition and gut health and
- 19:59the biomes that are going to carry from that food across, I
- 20:04think you're living soil ecosystems, especially ones like
- 20:07that you've done yourself and that haven't gone through a
- 20:10washing and sterilizing process that they have to go through to
- 20:13go into stores. You're not going to beat it.
- 20:17But I'd say in general from what people are growing in at home,
- 20:20like if they bought a bag of soil.
- 20:23And grew a plant in that. Or if they bought a hydroponic
- 20:26system and grew a plant in that. From what I know about some of
- 20:29those potting mixes, they'd probably get better nutrition
- 20:33from the hydroponics that that they'd grow.
- 20:36Yeah, honestly, I tend to agree with a lot of what you just
- 20:39said, man. I think you've nailed it in
- 20:41terms of just saying it really depends on how hard out you're
- 20:45going in terms of really nurturing the soil, the living
- 20:48soil itself. And if it is conventional
- 20:51farming, it's exactly the same. They're just putting in the
- 20:54exact amount of nutrients that they can just get away with for
- 20:57cost to then provide to be able to just get absolutely maximum
- 21:02profits and maximum, you know, maximum bottom line at the end
- 21:06of the day. So all of these companies in the
- 21:09big box stores that you're seeing, they're just putting
- 21:11this produce there for a minimal margin and it doesn't actually
- 21:16correlate to high nutrition. So, but the fact is that it can
- 21:20be done, like you said, in a hydroponic thing.
- 21:22And I think that's really promising for this food shortage
- 21:25or food crisis or whatever food supply crisis that we're in, in
- 21:29terms of how do we supply everybody with nutrient dense
- 21:33food. If more people had balconies or
- 21:36a little cupboard under the stairs that they want to set a
- 21:38little setup in, they can start growing stuff.
- 21:41And it is possible to do it with a high nutrient content if
- 21:46you're doing it hydroponically. And like you mentioned before,
- 21:51you can get a tent, an artificial LED light fans, all
- 21:55that gear and still grow in a soil bed in the tent if you
- 22:00really want to. Like you don't have to do
- 22:02hydroponics. That's that's very true.
- 22:04More difficult for you to move that ecosystem that you've
- 22:08created once you put it there. So you really want it to be more
- 22:11of a permanent fixture? Yeah, I, I agree with that too.
- 22:14And yeah, I think though, I want to highlight the importance of
- 22:18hydroponics because obviously, you know, you can, there is a,
- 22:22there is a space for it. And I'm a massive soil guy, and
- 22:25I agree with everything that you said about trying to ultimately
- 22:29do that for everyone in soil. But it seems like unachievable
- 22:34in this current world where we've got so many people stacked
- 22:36on top of each other. We may as well make use of the
- 22:40ability to grow things with a different methodology,
- 22:43technology, to be able to grow some healthy food for people
- 22:46rather than focus on these big chains, the terrible food
- 22:50quality, all of this kind of thing at.
- 22:53The end of the day, you know low nutritional food is better than
- 22:57no food. Yeah, yeah.
- 22:59Exactly right, exactly right. So.
- 23:01And and. We're on our way there.
- 23:03Yeah, and like in in big cities like San Francisco where they've
- 23:08started to do the vertical farming, there's a lot of
- 23:10criticism around it. They're kind of limited on what
- 23:12crops they can grow at the moment.
- 23:13But the fact is that the land that they're using is only like
- 23:17it's not even a block, you know, and but vertically wise it it
- 23:21may as well be a several acres, could be 10 acres worth of
- 23:25crops. But the the land footprint in
- 23:28terms of like your in environmental impact is actually
- 23:32a lot lower. And those systems are built to
- 23:34be entirely recycling systems. So they don't waste any water
- 23:39and the nutrition is completely used and recycled.
- 23:42So maybe it's not as ideal as a living soil product, but there's
- 23:47huge benefits and and like you said in this current situation
- 23:52we're in so. Yeah, you're right man.
- 23:56There is certainly a place for that.
- 23:57That vertical stuff is pretty cool looking.
- 24:02Hey guys, really quickly jumping in.
- 24:04I just want to remind you if you are not subscribed to this show,
- 24:07that is the number one thing that you can do to show me your
- 24:10support. So if you're finding value from
- 24:12this conversation and you're deeply engaged, I would love you
- 24:15to hit the follow or subscribe button.
- 24:17All right, back to the show. I wonder if we can move into
- 24:21like environment and setting up artificial environments.
- 24:24If if you can, you've obviously got and sell a lot of different
- 24:30gear. There's plenty of companies now
- 24:32that are making quite incredible gear.
- 24:35One of the big debates I guess, or one of the things that's now
- 24:40better than it used to be, is the quality of the light, the
- 24:44ability to dial in the spectrum based on the type of setting
- 24:49that you want for the type of plant.
- 24:51They have these broad spectrum LEDs which are good on energy.
- 24:55They're not going to heat up like these old halogen bulbs and
- 24:58things that would just cause so much heat inside your tents.
- 25:02Can you talk to me about the basics of lighting first and
- 25:08foremost, and then we'll get into kind of just environmental
- 25:11control and how important that is.
- 25:13So just talk about lighting and what you would recommend to
- 25:16people when choosing lights. Yeah, no worries.
- 25:22So the first, just the the first thing I just want to say is that
- 25:27like in in protected cropping, you're we like to say you're
- 25:31you're the God, right? You're you're your nature,
- 25:33you're you're the environment, you're everything.
- 25:36So you need to be aware of everything.
- 25:39The fan, all the gear we sell is the environment and the 1st
- 25:43place people try to cheap out is on the environment and then they
- 25:46have issues and then the first thing they blame is the
- 25:48nutrient. But environment is is crucial
- 25:53and LE DS have made a huge change in the last even five
- 25:57years. The the first ones on the market
- 26:00were absolutely horrible and a lot of people had very bad
- 26:04experiences with them. But in Australia, LE DS are
- 26:08super essential, especially Queensland, northern QLD,
- 26:13Equatorial zones, anywhere. That's a lot of heat naturally,
- 26:18even if you're in a house, like you don't want to be running air
- 26:20con either. So CMH bulbs, ceramic metal
- 26:26halides came out just before LE DS and they were actually
- 26:31incredible technology that's very similar on electrical
- 26:36usage. They're also they're bald,
- 26:38sorry, but they're very good on electrical usage and they mimic
- 26:42the sun very closely. The only issue with those is
- 26:47that you have to replace them and they still run more
- 26:53traditional ballasts, which are or drivers, early light drivers
- 26:57that that could be flame hazards and all kinds of things.
- 27:02LE DS are a lot safer. The diodes are basically grown.
- 27:09They're like a crystal that's grown.
- 27:11There's different grades of them, which is why you get cheap
- 27:13and expensive ones. Yeah, if you don't know that,
- 27:15yeah, look into. It.
- 27:16I really know that, yeah. That's why you often see like
- 27:19people nitpicking like you know, what company and what type are
- 27:23they? So the LE DS now they are using
- 27:26basically the bulbs that we used to use, they put out a lot of
- 27:29energy as basically just heat as you're really far red spectrums
- 27:34that you plant didn't necessarily totally use did a
- 27:38little bit which we've had to replace in the LE DS.
- 27:43The full spectrum LE DS is what you generally want to go for and
- 27:47I think even the examples of newer lights that have very like
- 27:54you can change every little spectrum on the light.
- 27:57I think again, it's one of those things where you basically have
- 28:00to be a scientist to understand what you're what you're actually
- 28:03changing. I mean, you can have a lot of
- 28:05people giving you feedback and your mate might have one and go,
- 28:08oh mate, I turned this red all the way up and I had way better
- 28:11result, you know, and maybe they hit the nail on the head, but is
- 28:15changing yellow to 30 and red to 90 and blue to say, is that
- 28:18really what the plant wants? I mean, all the plants
- 28:22basically, they all developed in natural sunlight.
- 28:28So at the end of the day, what we try to do is just find a full
- 28:31spectrum lighting. I still think it's pretty much
- 28:33unless you're in a very specialized field, in a
- 28:37commercial aspect where you're looking for every 1% of change,
- 28:43it's best just to go full spectrum.
- 28:45And they do come very, very, very close.
- 28:48They're within the mid to high 90s now of close to the sun
- 28:51spectrum. But we often refer to it as π
- 28:55lighting, your photosynthetic active radiation, the stuff the
- 28:59plant can actually use. And they still play with it.
- 29:03They've played with it a lot. And you'll often find that the
- 29:07only real difference is that if you're only growing racks of
- 29:12microgreens or lettuce or something that's a quick
- 29:17turnover leafy green that you probably a lot of these bigger
- 29:21lights are designed with bloom enhancers like red enhancers for
- 29:27your growing crops for a late season.
- 29:29So which can be used by those vegetables and you can grow them
- 29:33just fine. But usually you won't encounter
- 29:36that encounter that over 200 Watt light because it's not
- 29:41really. I mean you'll only get the Reds
- 29:43once. You usually go over 2 to 300
- 29:46Watt light unless the the lower light is specifically made for
- 29:52flowering or fruiting if any of that makes sense.
- 29:55I don't know if that's really what you asked.
- 29:56Yeah, absolutely right. That's.
- 29:58Kind of where we're at, but energy wise, heat wise,
- 30:02significant difference, huge, huge impact on not only the
- 30:06energy on the environment demand, but also on your, your
- 30:10bill. Australia is horrific for
- 30:12electrical and you know, there are advantages of bulbs, but you
- 30:20know, in in I think Oregon and America, they actually banned
- 30:24bulbs a while back because they got dumped commercially in
- 30:29landfills so much that the mercury levels were so high in
- 30:32the landfill that yeah, there's lots of advantages to LE DS, you
- 30:36know, so, but that's where we're at and in, you know, just to
- 30:41finish that, you know, two years ago, if you wanted, say a 600
- 30:45Watt LED, which will run you what used to be kind of the
- 30:50equivalent of like 1000 Watt bulb out of power, it's now 600
- 30:55watts. But if you were to buy one of
- 30:58those two years ago, you were spending $2000 for a lot and
- 31:04you'd kind of need a light that size to get a really good
- 31:07fruiting crop. And you can buy that same light
- 31:10for five, $600.00. So it's really made getting into
- 31:15it a little way easier for people.
- 31:17Yeah, that's really it. Because the technology I've
- 31:20noticed in terms of like you say, the last five years, it's
- 31:23just become way more accessible and they've got way more options
- 31:26as well. Introducing like the AI systems
- 31:31that can control all of the different elements.
- 31:33Like something like a company like AC Infinity just has it
- 31:36dialed in terms of their, their AI system where you can
- 31:40literally almost set and forget. Once these machines are up and
- 31:43running, obviously there's there's so much that can be gone
- 31:48into the environment. The indoor growing, you know how
- 31:53much of the daily light that each plant is getting, the par
- 31:57reading like you were mentioning, how far away the
- 31:59light is from the plant, the hours of lighting that you're
- 32:02supplying. You can literally play God in in
- 32:06so many instances and creating that environment is there.
- 32:11Like I know you said it mimics the sun say like 90% is there.
- 32:17What's my question in that 10%, what are we noticing that is
- 32:23missing from an indoor grown crop compared to a sun grown
- 32:27crop? What?
- 32:28What do we know about what's missing in that 10%?
- 32:33Well, like us, like I referred to like the, the, the PA what
- 32:38what the plants actually are using in terms of the light
- 32:41waves, the colors they're using really goes from like 440
- 32:46nanometers to like 770 nanometers.
- 32:52So I hope I got the terminology right.
- 32:56Yeah, that's right. But basically there is more
- 32:59outside of that. How do we know that they're not
- 33:03using that spectrum that's outside of it.
- 33:06So like you said, we we've gone right down to one side and on of
- 33:10the infrared, right up to the ultraviolet and we kind of got
- 33:14that last little 10% on either side of the scale.
- 33:18How do we know that they're not using that?
- 33:20Is that because do you like, I'm not putting you on the spot, but
- 33:23I just mean in terms of like, do we know that they've only
- 33:27studied that? We only have instrumentation to
- 33:29read that, you know, how do we know that the plant isn't
- 33:34necessarily using that? Is that what people are
- 33:36studying, I presume in these lighting companies and all that
- 33:39kind of thing? Yeah, No, no, that's a very
- 33:41valid question. And look, I'm a strong believer
- 33:43in, you know, like I studied science, but I'm a strong
- 33:45believer in, you know, never believing that we know things
- 33:50for certain. So, but yes, as you said, like
- 33:55it's been decades of because again, money drives this.
- 34:00So if there's light waves that are useful to somebody, they
- 34:04will find them. If there's light waves that
- 34:06they're going, this wave is not contributing anything.
- 34:09It's just costing us power. They won't use it.
- 34:11Plants outside may very well be using a lot of the waves we
- 34:14don't use, but they might be using it in such a minuscule way
- 34:18that really to your bottom line, like of this amazing, big, juicy
- 34:23nutritional tomato, you probably didn't need that one or it
- 34:28wasn't you know it. The fact that you didn't have it
- 34:31didn't stop you from getting there.
- 34:32So kind of to that point. And I and it also comes into,
- 34:38like I said, the making the diodes themselves, like there's
- 34:42still technology advancements that can be made in terms of
- 34:44like how do we make diodes that reach these these areas that
- 34:48we're not getting? And the UV ones that I was
- 34:52starting to touch on, the UV ones, they're very damaging,
- 34:56obviously like UVAUVBUVC. So they're not ones that they're
- 35:01going to include because they can cause harm, but your plant
- 35:05definitely uses them. So you can buy supplemental bars
- 35:08to be used in a Safeway, but they're separate.
- 35:12The other thing is that those diets don't last as long.
- 35:14So if they put them on a lot, they're going to degrade well
- 35:18before your warranty runs out, like they're not going to be
- 35:20going by the time your light, the other diodes will go another
- 35:24eight years and your UV ones are burnt out in three.
- 35:28So that's the reason why there's always going to be like that bit
- 35:32of lacking. You know, there's there's things
- 35:34that they either find that just aren't necessary to the bottom
- 35:38line or your or the cost to you and also the ones that are
- 35:43harmful and you can supplement them in.
- 35:45But that's generally why you're never going to have 100%.
- 35:48You know natural sunlight is the best.
- 35:51Yeah. Again, if we have these lights
- 35:54because they're situations where we can't use it so.
- 35:58Yeah. And as you've mentioned a couple
- 36:00of times, we we lack 90 something percent there.
- 36:03And you know that was really interesting.
- 36:06Thank you. About the the UV and what that
- 36:08does to the diodes and basically coming down to the bottom line
- 36:12again, that's super interesting to understand why I wonder now
- 36:17if you can talk to me about humidity, how how important is
- 36:22humidity And also if hang on, let's go with that, how
- 36:28important is humidity? I'll save the second question
- 36:30after that. Well, it's one of the essential
- 36:32elements in your growing situation, like your plants to
- 36:37transpire require certain pressure differences between the
- 36:41levels inside the leaves and the stomata in the outside of the
- 36:44plant. So humidity has a lot to do with
- 36:47your pressure difference. That's why you hear about VPD
- 36:49like your vapor pressure difference.
- 36:51And commercially they use humidity deficits and all kinds
- 36:56of different terminology that all mean different specific
- 36:59things. But pretty much you're trying
- 37:01to, again, it comes down to years of research, finding out
- 37:05what certain plants require to get the most response and at
- 37:10what time of that plant's life to get the most response.
- 37:13So humidity in a controlled area is something that you have to
- 37:17introduce or control depending on what you're bringing in from
- 37:22outside. And if it's not correct, you
- 37:26won't get the result you need. Outside you have, you don't have
- 37:30that exact control, you'd have to kind of just leave it up to
- 37:34the environment. But you have the advantage of
- 37:37unlimited fresh air and free air flow.
- 37:44And UVUV sterilizes a lot of pathogens.
- 37:47So if you don't have them inside your tent, the UV, then that's
- 37:51another thing that you don't get.
- 37:52And there's also a lot of like O3 in the rain, which is also
- 37:58sterilizing. So a big difference as to why
- 38:01your tap water, there's lots of reasons, but a big difference as
- 38:04to why your tap water is never going to be as good as
- 38:06rainwater, fresh rainwater, I should say.
- 38:09But yeah, so those elements, like if you just have high
- 38:12humidity inside, you're opening up to a lot of problems.
- 38:16And if you have it too low, you plan either way.
- 38:18If it's not right, your plan is not going to produce so strictly
- 38:24important, but it's one of the the several elements that has to
- 38:27be right, so. Yeah.
- 38:28Well, that's what I was going to ask you next is like if you had
- 38:31to, if you had to pinpoint like what some of the main things to
- 38:38focus on if you're growing in there, because often it's like
- 38:41just focus on the weakest link 1st and try and move up the
- 38:44chain. And it's incredibly difficult to
- 38:46manage airflow, oxygen coming in, but also controlling the
- 38:51temperature because you want fresh air for, you know, CO2 and
- 38:56oxygen exchange and all of this. You want temperature to stay the
- 39:02same roughly. You don't want to have too
- 39:04drastic fluctuations in temperature or have to run air
- 39:07con like you said. And then you've got this
- 39:10humidity as well. So if you've got something
- 39:12pumping out humidity and then you've got it's getting too hot
- 39:16and you're having to extract all the air, you're having to
- 39:18balance all of these things within that environment.
- 39:22Outside. We see natural fluctuations in
- 39:26in the temperature and then the humidity across the day.
- 39:29And I know that they're starting to be able to bring this
- 39:31technology in into the automated systems where they can do like a
- 39:35sunrise, sunset type thing with the lights and, and increase
- 39:39humidity in the morning or the middle of the day, whatever it
- 39:42needs. But yeah, where are the common
- 39:46problems that you see people sort of commonly coming up
- 39:50against? And then yeah, what are the main
- 39:52ones to focus on to fix like temperature, humidity, lighting,
- 39:56blah blah blah. Yep, great question because it's
- 40:01the first thing we talk to every customer about #1 genetics,
- 40:06genetics, genetics, genetics. The better your genetics you
- 40:09start with, the better your result, the better.
- 40:12The stronger the plant, the more resilient it's going to be, the
- 40:14better yield you're going to get.
- 40:16Like Snipe? I look, this is just an
- 40:18arbitrary number, but it's like, say you're like, I want to get 2
- 40:21kilos off this plant of whatever.
- 40:24If you buy a plant or put a plant in that's just not able to
- 40:28do 2 kilos and you're going, what am I doing wrong?
- 40:31Genetics is number 12 environment.
- 40:35So that has to do with basically the main three elements of your
- 40:39temperature, your humidity and your lighting.
- 40:45You can't really put any of those in preference of each
- 40:47other because they all have to be in balance.
- 40:49So we like to say 1% of light is 1% of yield kind of thing.
- 40:52So if you don't have enough light, you're going to limit
- 40:55your yield. But there is a threshold and you
- 40:57really need to know your plant and the threshold second to that
- 41:03for the what your plant needs, the temperature and humidity
- 41:07always work in balance. So if they're not at the right
- 41:11balance for what you're trying to achieve at that time, then
- 41:14you're not going to get the best results.
- 41:15If you can sort of keep them in a general, most of us at home
- 41:19are just trying to keep it in a range that we know is safe.
- 41:22We don't have that kind of high technology and unlimited
- 41:25resources to keep it at, you know, within one percent, 2% of
- 41:29value. And look, you can sway 5 to 10%
- 41:34and anything and still get really, really good results and
- 41:36not have to stress about it. And then from there, it'll be,
- 41:41you know, you're, you're basically your nutrient and
- 41:46water, but I'd say it's more your watering and how effective
- 41:51you're watering more than the nutrient itself.
- 41:54The nutrient is nearly dead last.
- 41:56It's the first thing, like I said before, that people
- 41:58complain about and it's the first thing that they try to
- 42:01fix, but it's usually the last thing you need to think about.
- 42:05A lot of the time when they're like, this nutrient is burning
- 42:07me, it's because they're not irrigating enough or, you know,
- 42:12often enough or if they're going, I've got nitrogen
- 42:15deficiency. It's like, well, you've been
- 42:17watering way too much and the plant has no oxygen and it's
- 42:21sacrificing leaves because it's trying to maintain.
- 42:24It can't take up nutrients if it's waterlogged and the root
- 42:27pressure is too high and. Look, lastly, man, I know you're
- 42:30a busy man. You're trying to hold down the
- 42:32store at the same time as having this conversation, so I really
- 42:35appreciate that. But lastly, what's like for you
- 42:40yourself in terms of a grower, whether you're growing
- 42:44hydroponically or whatever, what's exciting for you at the
- 42:48moment? What sort of things are you
- 42:49thinking about in your growing or just helping people with?
- 42:52Or what's some exciting stuff that you're thinking about at
- 42:55the moment? Garden related?
- 42:59There's a lot going on. There's a lot going on.
- 43:03So I, you know, we, we are big advocators for the, the medical
- 43:10cannabis space in Australia. We're big advocators for the
- 43:14health industry that's around that and also the, you know,
- 43:19renewable resources industry that's behind that as well.
- 43:22So we're always keeping an eye on that.
- 43:24And because that industry is really like a fairly, it's very
- 43:27new to Australia. It's been around years now, but
- 43:30it is still a bit of a scramble. But we're, we're always excited
- 43:34to try and see if that, because it's not only that, it's also a
- 43:37huge economic thing for Australia.
- 43:41So where we can't engage directly in that.
- 43:43I mean, I was, I, I worked in medical facilities, but we
- 43:49obviously in the store, we can't engage with illegal activity,
- 43:52but we are always very excited about that industry and we try
- 43:54to stay up to date with that industry and we have a lot of
- 43:58friends and partners in that industry.
- 44:00So that's hydroponically and organically and every aspect of
- 44:05the, the ability to get into this is easier than ever now
- 44:08because the like you said, companies like AC Infinity, not
- 44:13trying to plug them, but they have driven, you know, a sort of
- 44:16a standard and it's made companies sort of had to broaden
- 44:19their aspects. And now there's so many options
- 44:22for people that when they walk in, it's like, I can set you up
- 44:24and it's going to cost you. What it cost me to buy one light
- 44:27two years ago is amazing, which is giving a lot more power to
- 44:30people to do things just as a quick setup at home.
- 44:33And in situations where they can't do it, you know, there's
- 44:36some incredible people doing stuff that you just couldn't
- 44:40really manage outside because it has to be so specific.
- 44:44And the other thing is it is an exciting field in protected
- 44:47cropping in general because whether you're in soil or not,
- 44:51because we are looking at climate issues and outdoor
- 44:56farmers are really struggling with that.
- 44:59And it is really not cheap to set up indoor facilities at that
- 45:05scale. But the more that we can and the
- 45:08more that they are, which they are trying to now, you're kind
- 45:11of securing that food future regardless of how you're doing
- 45:15it. And because it's now protected
- 45:17cropping, they can also use crop steering to a greater extent to
- 45:21get better results for people, better crop protection and a
- 45:26reduction of pesticides because you're not so exposed.
- 45:29So that's also really cool too. You're right.
- 45:32And I just, oh, sorry, I just wanted to jump in on that point.
- 45:37You're right about we're not putting pesticides through back
- 45:40into the environment. We're not spraying anything like
- 45:43it's all contained within this solar system.
- 45:46And if we can get it super accurate to the point where it
- 45:50is like copy and paste, it's going to be the same.
- 45:53You know, the product is going to be the same every time you do
- 45:57it because you're doing it exactly the same.
- 45:59It's this rigorous process that's kind of locked in and
- 46:03very exact and very scientific. We know that we can do it for
- 46:07cheap. We cheap enough.
- 46:09We know that we can supply food to a lot of people this way and
- 46:13get people growing themselves this way.
- 46:15And it does not impact the climate in a lot of ways unless
- 46:19it's like based on the energy consumption itself in terms of
- 46:23lighting and things like that. But it's certainly promising.
- 46:26It really gives me a lot of good ideas for the food crisis.
- 46:31Well, just to touch on that, the the most, the thing that I think
- 46:34is the most incredible is that I wish, I wish I knew better the
- 46:39exact countries, but there's a fair few European countries
- 46:42where you cannot have a protected facility if it's not
- 46:460% waste. And even though they're using
- 46:50electricity for lighting, a lot of them are trying to do half
- 46:54artificial and half they only use artificial lighting on
- 46:57systems where the light will come up to meet the power level
- 46:59if the sunlight isn't. So you're, you're working to
- 47:02sort of get consistency, but you're you're reducing energy
- 47:05costs. But the big thing that a lot of
- 47:07people don't think about when it comes to the hydroponics is that
- 47:11it is always been an incredible water saving system.
- 47:16So even though, you know, it seems less natural, I mean,
- 47:19there are ways of doing that with advanced soil systems of
- 47:24the bright right amount of composting, cover cropping,
- 47:26planting the soil use, you know, moisture retention.
- 47:30But in general, compared to my soil farming, hydroponics, you
- 47:34know, you're not going to get this hot day where it just
- 47:36evaporates into the atmosphere. It'll evaporate into the space
- 47:40and then collect and then you reuse it back, you filter it,
- 47:42you clean it, you can go back into watering again.
- 47:46And so the water usage is significant.
- 47:48And in those overseas countries where they've had the legacy and
- 47:53the money to do so and the four Fort to do so, they it's almost
- 47:57like they never have to put water into the facility.
- 48:01Yeah, you're right. They don't.
- 48:03It's like it's saving water continuously.
- 48:04You're recycling and and you said it's just a lot of
- 48:07recycling. And then if the nutrients
- 48:11themselves are cheap enough, they're easily made and they're
- 48:16widely available, it means that more people can access it.
- 48:19So I think it's really good, man.
- 48:22It's a really, really exciting time.
- 48:24And I think hydroponics certainly has a place in terms
- 48:27of moving forward for this food security for our planet.
- 48:32Well, I like the fact that you like people like yourself
- 48:37advocating for organic growth as well.
- 48:39Like like I said, we do advocate for organic growth and we do
- 48:42have soil partners here and we have a lot of maybe like a third
- 48:49of our customer base are all in organic systems.
- 48:53So it's good anyone to help spread and get that information
- 48:57out there is great. So I appreciate that.
- 49:00And we never touched upon microbes, but that is that is
- 49:03also getting used highly in hydroponics as well might only
- 49:07in really subsite straight systems.
- 49:10And they're starting to find that it's more a bacteria is
- 49:14more useful because it's immediate where it's fungal
- 49:16colonies take time and a lot of these crops are finished before
- 49:19the the colonies are ready to go.
- 49:22So, but there is a lot of that use too.
- 49:25So that's taking us away from more chemical use as well.
- 49:27And and that breeds into actual health, human health and
- 49:32product. You know your healthy product in
- 49:34the end as well. And then we have it, ladies and
- 49:54gentlemen, hydroponic growing is certainly something that is
- 49:57becoming widely accessible and used.
- 50:00So thank you to Bodie from Friends Hydroponics.
- 50:02Thank you to Fran and the team there for letting us steal him
- 50:06for the conversation. But if you want to learn more,
- 50:08you can go and check out Friends Hydroponics on Instagram.
