what is it that makes the sun capable of growing flowers right down to the bottom branches of 20 feet tall trees? (apart from its arc through the sky)
I agree for a carpet like canopy, low and closer would be the appropriate adjustment for efficiency.
Then like with my current grow I have one table with a bunch of phenos, some short and squat others pushing 6 feet.
I'm still getting adequate light down to the lower tops with the dual strips driven hard.
Diffuse light certainly has its benefits, would you say bringing lights closer makes them more diffuse or more point source like?
