In the LED tent I have two Apollo Horticulture 300W panels, one a bit older with 3w leds and three fans and a newer model with 5w leds and one bigger fan. The second came to replace the first when two rows of lights went out but I just never returned it and kept both up and running, another row of leds has since gone out in the older model so 3 rows total are out currently but new one has no issues. I believe the actual wattage draw on each is in the 130-140 range. I will also sometimes supplment with two 30 watt apollo screw in LEDs when it gets dense in the tent. People have suggested swapping LEDs out for a 250watt hps which I never considered before but I recently set up a carbon filter w/ exhaust fan anyway. I'll probably order a new round of strains to try running w/ my LEDs, ones that have stated better yields than Nirvava's Jock Horror and White Widow. Again, I'm leaning towards BlackJack, Chrystal, Rashberry cough, and maybe even Wonder Woman??? I still have an Ice seed to sprout and other Jock Horror's. Of the two Jock's I sprouted, one pheno was much better than the other, better looks, better smell, better smoke and better yields.
