palerider7777 Reviewed by palerider7777 on . Imortant question about roots Hello, I had just started my plants about 2 weeks ago and the roots are in the water of the hydro system, but there seems to be a problem. There is brownish yelloish stuff growing on the calk i used to old down my tubing and the brownish yellowish stuff is on the roots also?? does anyone know what is growing inside there (fungus or algae?) and how bad is it for the roots?
