Seven Leaf

I've been growing 30 years, but I did not see anywhere that those were 3 watt diodes, my bad. Had I seen that I would not have made the statement, however the principal of led was to remove heat from the equation, look at the height of sog setups, far less that 30" inches with no ill affects at all how can you explain how all those seedlings survive? Think before you speak.Eraserhead has it right respect!!!! seven leaf you really shouldn't be giving advice if you don't know what you are talking about
sorry just saying it as I know it If they were 1 watt diodes then maybe the distance would be ok
with 3 watt diodes seedligs wont preform well with the light closer than 30" and will suffer as a result
How much heat is generated? What are the lense angles ? The actual NM of the lights being used and photo intensity and wattage. those will ultimately determine height.
