Looks good man! Keep it up. What is your PAR on the plants with those lights ? I would try and inch them as close as possible without causing tacoing. I recommend every grower get a PAR meter and a thermal heat gun to read your plant top temps and really push your lights to their maximum potential. If you have the time check out my diary and give my profile a follow!
@LegacyMarketFarm, The light is still prototype, but currently working with 75% dim + sunrise and sunset, total consumption 400w , Average par 950 - 1250 in 120*120 area, under the light source, the temperature plus is 4+6 degrees on average , this is an advantage for me, it brings my leaf temperature and moisture balance to the ideal vpd point.
