Changed from reflector series to this one, I always had great results in terms of quality and quantity but what can I say about this one, the buds fattened like hps light. I always thought, according to my results, that mars hydro was one of the best leds, but this one has done an extraordinary job to the buds. I have never seen such fat, tight buds with the reflectors. I cant wait to test and other strains with this one. The previous pineapple express I grew with the reflector series was 720,00 grams, bit taller and as easy to grow as this one. With this lamp I reached 985,00 grams with densier monstrous and full of thc buds. But as I mentioned above best lights are combined with best nutrients
