First time growing cannabis and I have entered the flowering stage. I already have a 1500W light full spectrum (bloom+veg). I thinking of purchasing another one to maximize the yield. I am thinking of purchasing 1000W light full spectrum (bloom+veg). The question I have should I place the second light at the bottom so that lower leaves get light as well or just place it on top? And do I keep the second one on the full spectrum (the first light is on full-spectrum) or just bloom for red light? Any help would be much appreciated.
