2 pounds from one plant jesus christ! i'm hoping for 2 oz(per plant) for 2 plants, and i have 8 freakin CFL's haha.
If 2 pounds seems like an impossible number, you should remember that if it's grown outside with a long enough season, a cannabis plant can easily get more than 12 feet tall.
This question is asked way too much by noobs. Because yeild can be from a whole lot to a whole little It all depends on a lot of things of course. So i would say just do it.see how good you are. and then you tell us how many plants it takes
