Indoors I've averaged 1 to 1.5 ounces per plant. I can fit 8 plants in an appoximately 2' x 4' area I'm using pretty inexpensive lighting fixtures and the power is about 400 Watts.

Outdoors is all over the board! An outdoor plant may stunt to less than one ounce or shoot out over 6 feet tall and produce one or two pounds of beautiful dry bud.

I hope my performance report doesn't bum you out! <g>
