Hey I just read a cool article in Cannabis Culture about organic hydroponics.. check it out:

Organic Hydroponics

SgtPepper showed it to me.. anyways, my question is would there ever be a need to change the water in this set up? For those of you who don't want to read the article (you should though), the water in the res is just plain water... If it never needs to be replaced, then this would be a pretty sick system

:peace:
