The hardest part was trying to figure out how to replicate the misting/spraying. No matter what I read on aeroponics and hydroponics, few people talked about the pump they used. I started looking at misting kits but they needed something like 30-100psi, which from what I saw, an aquarium pump can't produce and pumps that could produce that were very expensive. Plus, the more I looked at the Aquamist system, the less it seemed like misting and more it seemed like spraying. I read up on the nozzles that people were using in the PVC tube style aeroponics setups and decided to go with something like those. In the end I ended up copying the EZ-Clone system more or less and using the same sprayers for the job. I got a handful of things from the local hydroponics store, but you can find them all online as well, just remember that Google is your friend. Here's my parts list:
35 Gallon Bin: about $15 from Walmart
10 feet of 1/2" inner diameter tube: about $8 from Home Depot
1 1/2" T fitting for the hose: about $3 from Home Depot
1 250 GPH pump: about $19 from the local Hydro store
4 EZ-Clone 360 degree spray nozzles: about $3 from the local Hydro store
8 3" Mesh Net Pots: about $4 from the local Hydro store
TOTAL PRICE: about $52
The 250 GPH pump is more than enough for these 4 sprayers. I could probably even get 6 sprayers on there, but this is all I needed for my application. I could also probably get away with a smaller pump, but I would have only saved a couple dollars so there's little point in exchanging it. Anyway, enough words, time for some pictures!
This is the pump, a relatively cheap 250 GPH pump that is very capable of feeding 4 spray nozzles.
As you can see, I'll be cutting 8 holes in the lid. I placed the spayer asembly (black tube with 4 holes drilled in, sprayers screwed into the holes and the T fitting tieing it all together) over the lid so you can see how it will be positioned in the bin.
Here are the sprayers in action. It's hard to make out, but they have quite a range. Once placed in the bin, I'll position the sprays so that water is hitting all of the pots.
I plan to prop up the hose so it is almost at the same height as the net pots. I'll be rooting in rockwool cubes and transplanting them to the pots, filling in the rest of the pots with clay pellets. I probably could have fit more than 8 pots in the system and/or used larger pots, but air circulation is always a concern and I'm not looking for insane yeilds so this will be just fine. In the video, they grew 300 plants in 1" pots with the Aquamist system, so 3" pots shouldn't be a problem and the roots end up growing down into the water anyway. My plan is a SoG setup producing yeilds every 2 weeks or so.
Hope this is informative enough to help people build their own setups and maybe give people some answers they needed. Post specific questions if you got em, but I'm learning on the fly so my feedback may be limited. I'll post some more pics and info when it's all up and running. Until then, cheers!
