Just want some experience’s from those that run hlg 600’s and 650’s.
this is my second grow, last one being 2.5 yrs ago.
I got my HLG at start of flower on my first grow, replacing a 1500 and 2, 600 w burples, Mag problems almost imediately. This grow same problems , I moved the light around and also the wattage, for now im settled at 40” and 300watts, hlg reccomeneds 24-30 inches at 350 watts. I know these lights push the plants hard, so i am adjusting.
What heights and wattage are other people running?
