A friend-of-a-friend has an aero tube setup using 6? diameter pvc tubes with 3? netcups in them. At a certain point, the roots were no longer hanging from the netpots being sprayed anymore --- they??re laying in the bottom of the tube (in approx 1? of flowing water). It seems to defeat the idea of aero if the roots are submerged; now it??s basically just a NFT system. Plants are about 1 foot tall, roots about 1 foot long, flowing in the direction of the drain.
I want to trim all the roots to just 2 ½ inches below the netpot (an inch or so above the draining water). Since they??re being sprayed with water constantly, why do they need more than the minimum roots? And I expect that by cutting them the plant will grow more roots out of the netpot, ending up with more, shorter roots. Which would be ideal. Has anyone ever done this? Is it safe hydro practice or will it reduce the plants ability to uptake nutrients or water?
thanks in advance
