DIY Aeroponic System

Taxonomy upgrade extras:

Hot on the heels of the Aeroponic AeroGarden blog, I'm now going to build a much bigger aeroponic system.

Rubbermaid type container (35 litre / 9 gallon capacity), hydroton grow rocks, rockwool, six aeroponic sprayers, 3" net containers, airstone, Sicce Nova flow adjustable water pump, 125w (6400K) Eco-CFL grow lamp, digital timer...

Container dimensions- Length x Width x Depth (480mm x 390mm x 310mm) or (18.89" x 15.35" x 12.20") 

A few tasters.

A few items   Larger picture

All built!

All built   Underneath showing the 3 inch net pots   Water pump and micro sprayers   All running   Grow hood & lamp with starting week seedlings.   Seedling just about to be planted.   Hydroton at the bottom...   And planted.

The aero sprayer assembly follows my original design I did for the AG. I have drilled and grommeted three holes in the top left of the box (for the water pump power lead and air lines from the air pump), two pieces of sponge were placed at either end of the 'T' bar, they absorb vibration and steady the bar.

I anyone wants more build/technical details then just ask.

So what's the plan for all this? I'm going to start growing some mixed lettuce seeds (using rockwool) in my Aeroponic AeroGarden Conversion - give this a try out. Once the plants have got some good growth, I'll take the rockwool out and plant them into this unit; the rockwool will be surrounded by the hydroton clay pebbles. I'll then turn the beast on and see what I can get out of it - see below...

I can't say I've ever heard of this line of nutrients, their website has some good information on mixing and what to use though.

I must say that this is overly complicated, you need five products to use on the veg. stage and six for flowering!

What do you intend to grow as some plants will be ruined by the high EC levels which they recommend, running an EC of 2.0 on lettuce will result in nutrient burn and bitterness for example - tomatoes however will be happy at this level.

Hello Supreme and welcome.

I answer to your question of mixing, do you mean what quantities to mix or whereabouts you should mix them i.e. in the same reservoir or in another and transfer the whole mixture to your grow tub.

We'll also need some more information about what nutes you've bought to help identify the product.

We will do our best to help you out so just ask away.

 

Gisette - interesting question about nute strength in aero, I'm not entirely sure that this only applies to the high pressure systems? What I have here is low pressure and I've not found a definitive answer about the reduction in strength. When I did this I ran a full complement of nutes and didn't reduce, I'll keep digging around and see what others have done.

I have so many questions about the setup I plan on using.  I purchased a nutrient kit that said it had all of the nutrients I need to get started, but where do I mix them in at?  I will take pictures of my aeroponic tube and see if anyone out here has any suggestions, or maybe even a step by step process I should follow.

Quite welcome, Supreme. You might want to peruse Peat's Guide to Hydroponics on our site. Aeroponics is slightly different, but similar.

Peat - would it be a useless oversimplification to say that aeroponic nutes should mix about the same as hydroponic nutes, except at maybe 75% strength?

Very, Very Helpful! Thank You so much and I plan to get educated more on the subject. I have many more questions about nutrients and how to add them to my aeroponic tube.

Supreme - welcome! You definitely need to start the seeds in one of the spongy brown things (bound peat moss, rapid rooters or whatever.) Then when the seedlings are bigger, the brown rooter with seedling in it, moves into a net pot of clay rocks.

I am new to this and have some seeds that are ready to go, do I just put the seeds in the clay rocks or do I need the dirt square that is around it? Any help is appreciated :)

Thank you all, your comments are appreciated.

hengis - the light timings were kept at 18 on and 6 off, the water pump I used was run 24/7. Next time I'll run it for 15 minutes on and 30 minutes off, this will give the air roots more of a chance rather than being 'drenched' continuously. The toms grow ended prematurely, the heatwave we had last year killed the whole plant off unfortunately - I was only about 3 weeks away from harvest. In case you missed the grow, it's here with some conversation we had on it.

 I'm adding my thanks to Peat, and all the others who have contributed.

You make this site very worthwhile and your time and efforts are appreciated by lofters like me.

 

Many thanks. (esp. for the photos and your experience/wisdom)
