How much bud could i get

Typically off a 6ft plant how much bud would i yield?

can't answer that, too many variables

anywhere from half an ounce to 2 pounds... somewhere in there... as stated above... there are to many variables to give you a answer...

Hard to say without knowing all about the lighting and the grow room in genaral,but i would say a min of 4 ounce.that if the grow room is not up to much if the growroom is a 1 then you are talking some seriouse weight .but i we need to know how many plants what lights what feed.impossible to say dude.

they will be outside with about 9 square feet of land

no one can give an accurate answer, regardless of the info you give
