Watts per sq ft. How many watts in your grow space

[Dabber]

My big space is 9 x 9 81 sq ft with 13 autocobs from @BigSm0 totaling 780 watts so I'm running 9.6 watts per sq ft

I'm running 1020 Real LED watts in a 5x5.

1 Platinum LED P300 = 180 watts
1 Platinum LED P300 = 180 watts
1 Platinum LED COB 1000 = 420 watts - unreleased light
1 Samsung kit = 240 watts - to add white light
Total = 1020 Real watts.

My diy setup was a bit over 500 watts from the wall, with 9 square feet, so a bit more than 55 watts/square foot - too much as it turned out... With the screw in bulbs I was using, I figure that max for the plants I grew was somewhere in the neighborhood of 35-40 watts/sq ft, and then only with some distance between bulbs and plants. The plants would likely have been very happy at less than 30 watts/sq.ft.

9.6 wow. That's a nice cheap bill considering the space! I run roughly 235-250 actual watts from qb in a 2x4x5. I dont see myself changing anything for a while. I like where I'm at.

@Dabber you plan on increasing from 9.6? them cobs do work.
