- 0:00Hello and welcome back to Hydroponics Daily. I'm Dr. Russell Sharp,
- 0:03your host, and this is your podcast for everything soilless cultivation.
- 0:08However, we're looking at soil today,
- 0:11specifically answering the question that often gets asked when we talk to customers
- 0:18about our hydroponic fertilizer, and that is,
- 0:21can you use hydroponic fertilizers when
- 0:25you're growing plants in soil so specifically plants
- 0:29that are growing in the ground in your garden or on
- 0:32a farm but also plants that are growing
- 0:35in containers plant pots where people have
- 0:37put soil or loam-based grow media so loam is another word for mineral soil as
- 0:45opposed to non-soil-based grow medias which we normally think of as being hydroponics
- 0:50so can those hydroponic fertilizers be used in soil either in the ground or in pots.
- 0:56So we're going to the potential pitfalls and potential benefits of using hydroponic
- 1:01fertilizers in that situation on today's episode.
- 1:04So the short answer is yes, but the actual how we can get to that situation
- 1:11has some nuances and it's not yes in every situation.
- 1:15So a hydroponic fertilizer contains all the nutrients that the plant needs.
- 1:18Now in hydroponics, most people use an A and a B fertilizer because they don't
- 1:23want the ingredients to react.
- 1:26Whereas in gold leaf, as it's called in the US or liquid gold in the UK.
- 1:31Our hydroponic fertilizer is a unique one-part fertilizer that contains all
- 1:36the nutrients without them reacting.
- 1:38Now that's very different to a garden fertilizer or a farm fertilizer,
- 1:42which normally is just NPK plus
- 1:45one or two micronutrients they don't need every single essential nutrient that's
- 1:51why they are cheaper and that's why they're a one part normally so yeah if you
- 1:56were to let's look at it this way it you couldn't use a garden fertilizer in
- 2:02hydroponics because you'd get a nutrient deficiency.
- 2:05But you and those fertilizers you don't get
- 2:08nutrient deficiency when you're growing in soil because they're relying on
- 2:10the soil to provide some of those macro and
- 2:13micronutrients however if you apply a hydroponic fertiliser
- 2:17into soil yes you can use it and you
- 2:20are then not relying on the soil for any
- 2:23of the nutrients so the plant might absorb nutrition from the soil that was
- 2:27already there and in addition to the nutrients you use so yes you can use a
- 2:33hydroponic fertiliser you might not need to use a hydroponic fertilizer though
- 2:37and it might be too expensive to do that but in certain situations you might
- 2:40think that it's the best situation.
- 2:42And i don't know if you can hear that that's the rain against the window it's
- 2:45really coming down here we've got a storm in the uk at the moment so you
- 2:49can use hydroponic fertilizer it's not always essential but
- 2:53it's not going to do any harm specifically there
- 2:57is nothing in a standard garden fertilizer that
- 3:00makes it suitable for garden soil or
- 3:03for farm soil it's just that it they're cheaper
- 3:07because they don't require it there's nothing specific specific formula that
- 3:11makes it stand out and works really well in synergy with the soil particles
- 3:15and mineral nutrition two important important points to consider are that hydroponic
- 3:20fertilizers are designed to be applied every time the plant gets irrigated in a hydroponic system.
- 3:27You don't do just water and then hydroponic nutrients once a week, for example.
- 3:35Whereas in a garden or a farm, you may fertilise the soil once a week with a
- 3:41fertiliser, once a fortnight, or even once a year in a farm-based system.
- 3:45So the instructions on the hydroponic fertiliser will
- 3:49not apply in that situation in all cases
- 3:51so you may need to quadruple the
- 3:55concentration you apply if you're only applying that hydroponic fertilizer
- 3:58once a week so consider that
- 4:01don't say this is one time where you
- 4:04can actually apply more fertilizer than it states on the bottle hydroponic fertilizer
- 4:09in for gold leaf or liquid gold as it's called in the uk we have full instructions
- 4:14for soil applications so you just need to consult them don't guess when it comes
- 4:18to that because always better to apply less than it is more when it comes to our fertilizers.
- 4:23The other thing to consider is if you're looking to get that extra yield bump
- 4:27from dechlorination, if you're applying once a week or once a fortnight,
- 4:32you're not going to get that bump from dechlorination if you're,
- 4:35irrigating or watering your plants with tap water in the time in between.
- 4:40So you could use a dechlorinator. In the UK we recommend Dr Hydro dechlorinator
- 4:46or if you're using liquid gold already, then we'll.
- 4:50Email me next time that you order a bottle and we will provide you with a free
- 4:55sample that will do more than enough water for those times in between you're using the liquid gold.
- 5:01So liquid gold and gold leaf, it dechlorinates instantly and it's inbuilt technology.
- 5:06So you don't need to worry about dechlorination.
- 5:08If you're using a standard A and B, then you're not getting that dechloration technology anyway,
- 5:13whether it's the time you're fertilizing or the
- 5:16time you're just irrigating with water i always recommend dechlorination
- 5:19because it is a significant yield bump you can get
- 5:22from just applying a very very
- 5:25few small drops to your to
- 5:28your tank or your watering can or your spray or
- 5:31anything like that so i definitely recommend it potential pitfalls
- 5:35can also include overdosing if you're not careful if
- 5:38you just if you apply hydroponics fertilizer every single time you
- 5:41water you might get a build-up and you
- 5:43might leach pollution into the waterways and
- 5:46the water system and that's not cool so don't be
- 5:50applying hydroponic fertilizers every time you water your
- 5:53plants unless you really know what you're doing and it's a low level if
- 5:57you're using a standard fertilizer that's not liquid gold
- 6:01then you could disrupt soil ph as well
- 6:04so the sweet spot ph 5.5 to
- 6:066.5 many soils are higher than
- 6:09that or lower than that if you're using a hydroponic fertilizer then
- 6:12that that won't correct the ph a standard
- 6:15a and b fertilizer won't correct the ph gold leaf
- 6:18or liquid gold as it's called in the uk that will correct the soil ph that's
- 6:22really good and then the tap water as well you you you if you've got really
- 6:28alkaline water then that might be an issue as well so there's certain situations
- 6:33where using handioponic fertilizers make really good scents.
- 6:36If you're using loam-based grow media in containers, hanging baskets,
- 6:42things like this, seedlings, propagation trays.
- 6:45Really high value, high density situations where you might be using soil or
- 6:49loam-based fertilizers, loam-based grow medias, definitely I'd use a hydroponic
- 6:54fertilizer there rather than a cheap and cheerful miracle grow phosphogen,
- 6:58tomorite type products or plants that
- 7:01have got a need for lots of calcium so if
- 7:05you're growing tomatoes in the ground i wouldn't use tomorite because
- 7:08it doesn't contain calcium and you could have issues such as
- 7:11blossom end rot as a result so i would use
- 7:14a hydroponic fertilizer and obviously i would use one of
- 7:17ours so for that but you can use anyone else's
- 7:20a and b fertilizer for growing tomatoes peppers tomatoes
- 7:24even potatoes and there's anything that loves loves a lot of calcium you you
- 7:29could get nutrient burn if apply too much remember hydroponic fertilizers always
- 7:33contain a lot of potassium and especially the additives as well so you're doubling
- 7:38up on additives as well if your soil has already got good levels of potassium
- 7:41that's a potential issue.
- 7:43And what else do we consider? We've talked about environmental considerations, talked about pH.
- 7:49Well, what else could we think about? Maybe if you were growing on a green roof.
- 7:55You had a living roof and you were seeing poor growth, you could use a hydroponic fertilizer.
- 8:01So on a green roof or a living roof, there's not much soil there.
- 8:07There's a small amount, it might be sand-based to allow quick drainage
- 8:10so in that situation you might get
- 8:13poor establishment and you really do want to have good
- 8:15establishment so that the grow media binds together doesn't
- 8:18get washed or blown away and so that would
- 8:21be a really good situation where you could use a hydroponic fertilizer
- 8:24so there's been a whistle stop tour
- 8:27of whether you can use hydroponic fertilizers in soil it's
- 8:31something we get asked a lot about and we
- 8:34recommend yes you can obviously you don't want to be applying fertilizer every
- 8:37time you irrigate so um
- 8:41i would only apply once every week
- 8:44or every fortnight and only during the growing growing season
- 8:47don't apply fertilizer after september in
- 8:51the uk and then all the way through to march really i
- 8:54wouldn't bother applying any fertilizer it's only going to
- 8:57cause it's going to waste money and it's going
- 8:59to lead to nitrite accumulation things like this nasty
- 9:02things like this so but during the growing season applying
- 9:05hydroponium fertilizers is a really good idea and then in between the fertilizer
- 9:09you might want to use a decolorinator as well when you're just watering your
- 9:12plants just to get an extra yield bump and so you can use an a and a b just
- 9:16be careful with ph correction and things like that in very alkaline or acidic
- 9:21soils they won't correct those issues but something like liquid gold leaf wood.
- 9:26So it's a very common issue we get asked a lot about.
- 9:30In the US we often get asked to release our pH perfect and dechlorinate the
- 9:35technology on its own without the nutrition because of this issue because so
- 9:40many people do only fertilize their plants once a week when they're grown in soil.
- 9:43It's something we looked at, it's something we may consider in the near future as well.
- 9:48So if you're interested in that, a product that just corrects pH
- 9:51and dechlorinates then let me know and
- 9:54we can i can put that through to the people in charge of
- 9:57actually delivering that in the us or north america
- 10:00in general so that's been hydroponics daily for
- 10:03today if you've got any questions let me
- 10:06know speak to us at utreema you'll find
- 10:09any of the emails will come to me eventually if you want to spell utreema it's
- 10:13latin for wasabi and we're a british based company and we make unique specialist
- 10:19fertilizers and inputs so if you've got any questions about any of those products
- 10:23as well or anything about groany in general then get in contact thank you very
