that or some systems use the method of raising the flood level until the roots get longer. Also a nft mat is a good investment. I am looking at this ad I got from bg hydro today and they have 40 in by 6 in trays with elbow opening, holes, on each end. They are like 11 bucks. I want some fun. Maybe I could use a lid and so nft, put a valve on the end and slow down the exit water. Or rockwool again, or one gallon pots or blah blah blah. I was reading NFT is the best, I cant remember if this is better than aero. I think you can manage it easty. Hydro is easier than people think. Rokcwool has some probs tho, lol. Silk sounds nice or raise flood level. It wont take more than a few weeks at most, to get to the floor,
