check out my pics on my profile. LED's are where its at. I used to use hps but not anymore. I am on my 2nd LED grow. There are alot of haters on here that will never admit that LED's work. My 1st grow was 4 indica plants with 2 glowpanel 45's. My partner was growing the same strain, (i got the clonees from him) 2 1000w hps for 16 plants. it stareted out as a test. my plants turned out better, denser heavier more crystalized budz. weight per plant was on par with his as well, he got maybe 2-3 grams more per plant, but mine where more dense and frosty and overall better quality, even by my partners admission.
