i would use what bilbo buddin suggested the smart/air pots they are pretty good for what your using or wilma system etc but on there own for soil coco etc you have to make sure you have tray on bottom to catch water trust me you'll have an abundace of roots as they air prune the root to force 2-3 more feeder roots of the one that has just been pruned
yeah he said the regular square pots are better too, but also said the netpots will work since I already have them. Just wanted to see if anyone has used both and could tell a difference. or if anyone has had any problems using netpots with no hydroton in the tray.
i believe it would greatly depend on the net pot size air pruning is ok but if its say a 3" little net pot thats a little to much pruning not enough room for roots to be very established.
i think it will work great with 6 inch net pots with no problem they will root into the hydroton nicely and the little stray roots will be air pruned when the canopy gets thicker anyway you wont have to worry as much for the lights will not cook them ither
