I built a few "growbuckets". They're just buckets full of water, nutrient and air stones in the bottom. The plants were started in a "fogponics" bucket which is working perfectly with perfect white roots, but when I place them in the "deep water culture" bucket the roots rot and the plants die. I think the water doesn't have enough oxygen, so I'm thinking... is it possible to use an air pump to create some kind of water spray in the water buckets? Kinda like an aerosol can. That's one of the options I'm considering. The other one is using my fogponics controller to make a pump fill the buckets every two minutes and let the water drain out into a bigger reservoir, that way the roots will have time to breath and never dry out.
