What kind of yields do you see int the 2x4 and the Rain forest?
Those auto pots can't work like that. The water is triggered to come into the pot when the soil or coco is dry threw a special vowlb that they have pattened and if you don't have a growing medium such as soil or coco/promix/sunshine then the water would just continually try to fill the pot until full and then your plants would just sit in a pool of water which is not O2 saturated.
