Nice chart......only it is rated for 25-30 watts per square foot though.

I would rather keep it up towards 50 watts psf.


Something to keep in mind!!!

Is it the same dispersion for HPS as well ?
Just curious.

I agree with tibs. 50 psf min for sure.

I've done grows from 40 to 100 wpsf. Personally I found the best to be at around 66wpsf. Basiclly a 1k over a 4x4. I did notice weight did increase some with the higher wpsf but controling the heat was a major bitch. So for now on I'll stick with 400's over 2 1/2 x 3 and 1k's over 4x4's.
