Lucky, 9 plants here can get you almost 5 years under our new American style judicial system "Harper" has flung on us, and god forbid the count is 16
who knows what will happen
I do 4 plants under 600W, about 4 - 5 weeks veg, and 8 - 10 weeks flower and produce just about 1500g or ~3.5 lbs; Using Leonardos' formula for my last grow:
4.5 weeks (33 days) + 9 weeks (63 days) =
96 days
1500g / 96 days =
15.625 gpd
And my space is a 5' x 5' x 8' area. That's
200 ft[SUP]3[/SUP]
15.625 gpd / 200 ft[SUP]3[/SUP] =
.078g ft[SUP]3[/SUP]/day
