Yield question

yeah i would recomend vegging till about a foot an a half or a 2 ft. becuase then they double in size durring flowering. and then you will have a nice size plant and probablly get maybe 2 ounces then.

IMHO you never really need 5 gallon buckets indoors, unless you have 5 foot bushy as hell monsters, which in that case you will need some serious side lighting. And in order for a plant to be that big you've spent at least 3 months vegging. Which is a waste of time. Root bound is a bit of a myth. Just water more often.
