Pith-off or monocloromine by Flairform is the best I have used (and I was growin' trees in rockwool... ) and it's cheap.... (I always source commercial grade nutrients and treatments)

Flower Child Reviewed by Flower Child on . brown roots : i'm sure Zandor knows Hello, i'm growing DWC with air stones and GH flora series. I know now that flora bio clogs the air stones. OK. But what causes that brown mud that sticks to the roots. I don't understand. Not in each bucket. I think it asphixiates the plant at last. Do you change air pump, air hoses on a regular base to avoid mold ? Thanks for answering. Fhydro Rating: 5
