- 0:00Hi welcome back to hydroponics daily today we're talking about another funky
- 0:04way to grow your plants and that's aeroponics so this system is very advanced
- 0:10it's not for beginners and it's but it is probably the most highly well it's
- 0:16it's known as the most productive and mostly,
- 0:20fastest way of growing plants if you can get it right so
- 0:23what it involves is you have a holding tank just like any of
- 0:26your system you have a pump and that pumps it into a
- 0:29closed area where the plant roots are but instead
- 0:33of being a film of water or a
- 0:35tank of water that the roots are in like in DWC or
- 0:38NFT it's a mist of fertigation solution
- 0:42so they mist the roots rather than and then
- 0:45rather than the actual water enveloping them
- 0:48and then the plants themselves the green tissue
- 0:51that sits on the outside so the foliage the stems are
- 0:53on the outside and they don't get exposed to
- 0:56this mist and because it's a mist rather than just a mass of water the aeration
- 1:04level is super high those roots are getting loads of oxygen and they can grow
- 1:08really rapidly and so that's why it's such a highly productive system if it's
- 1:12growing well and the system i've.
- 1:15Illustrated there is like a tp tent system and
- 1:19they're popular in asia and so you'd have a long
- 1:22running it's like tent a frame and the
- 1:24roots would go into that and then you might have a recirculatory system
- 1:27back in there or it might evaporate off and
- 1:30things like that depends depends on the parameters of your
- 1:33actual grow it's great for lettuce and herbs basil
- 1:37things like this you want to grow super fast and will
- 1:39be conducive to this obviously if you've got a very tall plant they're
- 1:43going to fall off the edges because this is not horizontal these are nearly
- 1:47vertical so you can pack a lot of plants in you've got supplementary lighting
- 1:50it's great for areas where you haven't got much space and it's a very light
- 1:55system as well so if you're going on a rooftop system then you don't,
- 2:00like DWC an Olympic sized swimming pool that's a lot of weight whereas here
- 2:05there's not a lot of weight it's only the tank which can be positioned elsewhere
- 2:08it doesn't have to be in the actual grow room.
- 2:11There are some major disadvantages with aeroponics. Two major disadvantages that I'm aware of.
- 2:16One is that the roots, because there's no medium for them to root into, often clump together.
- 2:22And when they clump together, you get biofilms enveloping them and they start
- 2:26to rot and they just don't absorb oxygen. It's covered in biofilms and algae.
- 2:31Algae is growing this system and they're very difficult to control.
- 2:34You know, normally in like NFT or DWC, you would apply hydrogen peroxide or
- 2:40some other sterolent to kill off the algae, but you're going to kill the roots in this system.
- 2:45And also you might expose workers to that peroxide as well, which is,
- 2:48you know, hydrogen peroxide is horrible stuff.
- 2:51Instant pain with hydrogen peroxide if it's strong enough. And then the other
- 2:55disadvantage is, you know, you're spraying mists in a warm environment all the
- 2:59time and that just screams Legionellas to me.
- 3:02So you need to be really careful you don't get a Legionnaires outbreak.
- 3:05And worst case scenario, you know, you get contamination of the crop,
- 3:08the leafy veg with with some sort of contaminant microbial contaminant
- 3:11so if you're really good at controlling algal
- 3:15growth in nft and dwc and you think you know
- 3:18you've got it locked down then aeroponics might be the system for
- 3:21you in hydroponics sort of
- 3:24amateur or side hustle hydroponics aeroponics
- 3:28is used very often for routing of
- 3:31cuttings lots of people see success with
- 3:33very small aeroponic systems so you
- 3:36know desktop size had aeroponic systems
- 3:39for rooting cuttings and they're you they're only
- 3:42in there for a short period of time so you don't get those build-up of biofilms
- 3:46and lots of oxygen get into the newly developing adventitious roots so if you
- 3:52most people start off with aeroponics and then they they move into some other
- 3:55system once their cuttings have rooted so for propagation aeroponics is often
- 4:01a good option so that's been the Hydroponics Daily for today. Thank you.
