thanks; isn't that mainly made for drip? would i modify it then? i read an article about an easy DWC diy setup and it seems easy and would be great. dwc seems like a lovely method. the one thin i'm concerned about is that the grow will be in a garage that is seperated from the main house, and there is no water in there. so i'd have to fill up a big rez. with water and bring it out, i'd also have issues with dispossing of old water regularly; a DWC system needs new water every couple weeks? i'm only growing a few plants so it wouldn't be that much to change, but still
