I had already bought net pots for my set up: I'm making a Passive Drip system. This is how I plan to run it. I have a shelf above my grow area (two chambers for perpetual one flower and one veg). I have a cooler on the top shelf, that the empty valve on the cooler connects to a 1/2" tubing down to a emitter splitter, to each plant. I've gotten 5" net pots to grow into. I'm using gravity to bring the water down, and I was going to use a 5" pvc tube that I bought, but I've changed to more like a plastic storage bin with a drain, to attach a 1/2" tube to go down into my "dumping reservoir" to well be dumped after the runoff. And I'll be watering them as needed for however long I need the water to run the coolers are about 10g, so they should be enough for full growth. (Running 10 emitters at .05gph it would drip for almost 22 hours straight, I'm doubting they'd need to use 10g of water though for a while) My problem is that I don't really want the roots to grow together. if I get the rockwool cubes with that plastic around them and give them holes to drain would that prevent the roots from going crazy and getting weaved together, what about in the net pots with this system. I'm just not too sure on that.
