how much does a plant yield?
UHHH?
i don't get it? Whats the question?

16 plants in 1 gallon (soil) containers, under a 1000 watt HPS should yield at least a LB....
if all goes well... or shall I say, if nothing goes wrong!

2lbs+ is also doable... 2+ ounces per plant... and should be your goal

does that help?

: ) SEEEEEEEEEEEEMORE
