I'd keep whatever I didn't end up killin'.... I've proven good at that. I'm harvesting tonight, so we should give pause in rememberence of the fine genetics I destroyed in my newbiedom.
What kind of lighting do you plan on using? I keep two mothers under a 400watter, and they grow way too fast for me! I'm thinking about scooping up a 250watter to handle the mother biz... Six strains sounds good, but do you have the room to handle all of 'em getting bushy?
