I am currently using aquashield, is that something like hygrozyme? if not i will get some, I do have all buckets on 2x4 and the control unit on floor. I did check the other plants roots and they r nice and healthy?? Tiny I was reading one of your earlier posts about putting the buckets higher than the control unit, so thats what i did when i started this last gro. The only thing I can think is that those roots clogged the line and the wet roots just gooped up real nice with no fresh water supply , as I said the other buckets r nice and healthy??
