Thanks all! Yes I re-visited the control bucket idea and did indeed go to a larger container, approx 10gal, which makes me overall around12-13 gal. I think that a larger controll res' should provide a more stable mix and make the ph and nute' mix easier to control. Ph is now running around 6.1-2... and I'm changing from Pure-blend to Fox Farm Grow Big...just to experiment. Overall i'm satisfied and just waiting untill they get to around 12" before going 12 12..What do ya think??
WeedCollegeGrad Reviewed by WeedCollegeGrad 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
