DWC (bubbler) has been the simplest and easiest form of hydro I have attempted to date. I veg for 2 weeks from clone (till they are around 10") and end up with a 3ft+ monsters.

Only big issue is changing out the res, which can be a serious pain in the ass.

As with all forms of hydro, your #1 factor to worry about is water temp. 68 degrees solid all the time and as long as you keep everything else within somewhat of a spec...youll blow up strong. Water temps over 72 and your in for a battle with algae and bacteria.
