the key is to feed heavy early on and foilar feed. once youve gotten to the point of "catch-up", its too late for higher yields. they will need water more frequently than in a larger pot. cant ever let em wilt either. ive seen it and done it and 10# is possible with certain strains.
no pics for you, doubting Thomas. lol
How early do you start vegging?
If I had total control over my situation (and soon will) I would start seed mid December indoors under HID's for a 2-3 month's veg, then move to the smarties ....
