Thank you CookieJar for everything, and I'm paying the generosity forward (and back, once he has his new tank up). Grows very well under: 1. 250w 14k MH w/actinics. 2. grows in both low flow and high flow, doesn't matter. 3. about 2'+ away from lights. DBTC rules: 1. frag 2x for dbtc before selling. (this can happen within a few months, grows quickly) 2. fragging for swaps is OK, but make sure you have a frag for yourself. 3. if my tank takes a crap, i'm first in line for a frag.
