my hydro guy told me these pots suck. Try them out and let me know what you think, My buddy showed them to me and they look like something you could make for around seven dollars for materials. But i haven't used em so i cant knock on emDUDE! where did you order those pots from? I seen those on a video the other day but have not seen them in any stores yet, Those airholes look like they can do some amazing things, how long have you been using them? do you notice a difference using them?
