I'm not getting only a half O from my plant, hell no! I was just saying as an estimate as some growers only get that much.

I grow various strains and I always top them. I pull of about 20-30g's per plant every 2 months or so. Not bad with only a 100W of CFL's for veg. and a 150Whps for flowering in a small ass space.

Right now I have Afghan x Jack Herer in flowering for almost 2 weeks now, and I have only about half a foot left of head room. I let things get too big before swicting to 12/12, and now I'll have to start bending the branches.
