If I'm gonna die I wanna be high .
Good Morning @Mossy A.F'N. Stoners .
Tricky question sir it all has to do with the Par + footprint of your COBs . Most here start a 24 " above the canopy . As far as the in between part best suggestion I have received is to try holding one of the ground and see what the footprint looks like . There may be more suggestions to follow .I'm new in the Chip on Board LED game and still looking for that sweet spot.
What is safe yet efficient distance between the cobs and the canopy.
Also spacing between the cobs.
