Does anybody know what this stuff is growing on the roots?

there's nothing in the solution as far as slime or anything like that. the reservoir is clean. it's just on the roots.
i heard it's bad to use h202 with certain types of nutes. is that true?
i'm using voodoo juice right now (awesome product by the way). and i'm waiting for the pirahnna that i ordered. i heard alot of good things about it. also that it kills mold. but it's taking forever to arrive. i'll add a couple airstones for now.

I love voodoo juice too!!! As far as h202 you cannot use it with organic nutes/additives...such as voodoo juice. h202 kills all microbes beneficial as well as harmful bacteria.

If you are using chemical nutes, however: You can use h202.

Buy some hygrozyme! I know you don't mind spending the $$$, because I know what Voodoo Juice costs. You will like the hygrozyme Too!:smokin:

Hope this helps.
