I had a white film on the rez water also, but only in the veg stage because now that it's the 12/12 cycle, this did not appear again. Anyway, it's no major problem

fhydro Reviewed by fhydro on . White water!! Hey all! I built a 8 pot DWC system and it has about 6 gallon total capacity. I'm using a 1/2 oz. per gallon mix of Botonicare Pure-blend nutes'. and the babes are about 8" tall. I'm noticing that in the controll res' a whitish frothy film is turning up...has anyone seen this before? I think ists just waste by-product from the roots...any guesses? Rating: 5
