if you are in norcal, ditch the single plant idea man. We don't have plant restrictions
you'll get whole extra harvests in each yr by a shorter vege time.
and if you aren't doing veganics as a "religion" then I wouldn't bother with it, it's not any "cleaner" than a proper organic grow.
i'd make a normal recipe, and stuff four to six plants under each light.
and not to be mister negative, but a lb INSIDE is a lofty goal off one plant.
Off four or six plants topped to four colas?
hell yea you could, and you'd get more harvests per yr too.
plus the extra vege time (the added 6 hrs or more per day) are gonna add up, and then having a plant in a container for that long can lead to issues..
just be SURE you want to go this route..
Cuz i'd do it differently, but we are all different.
