Ms. Fox: this is straight out of my growers bible.
Labrat: i hear ya man, i plan on doing pretty much exactly what you are, thanks for the idea of the bigger tub for flowering. do you use distilled water?
ok, but heres what i dont get, in my bible it shows that cutaway of a DWC ^ no feed tube right. but in the description it says to have a drip tube. my guess is for when its to small to reach the water, but it doesnt say. and in the cutaway of the top feed, has the pump and feed tube, along with the airstone, so it basically contradicts itself. but idk, i plan on doing it with no feed tubes, and having a veg and a flower set up, with a spare tub for both probably.
