Rusty Trichome Reviewed by Rusty Trichome on . WTF is THIS?!? so i finally did a few things.. looked at a bunch of rootbound rootballs found the soil bone dry and transplanted.. now for the question.. what is this and how bad is it? the rest of the rootballs looked like the last pic so i have to assume it was because it was in a clear milk jug?? thanks for helping Rating: 5
