I can see where you guys are coming from but this guy is not really promoting anyone apart from some gay trimming tool; he's just explaining in detail the products and methods he is using, if you think he done that setup just to fool you into switching to LED you are plain ignorant, Don't knock em till you try it!
Obviously if you don't have to worry about electricity bills, or flying pigs looking for your massive thermal prints then no worries; get massive yields from a guaranteed source of power, but LED's are the future weather you like it or not. I do find it hard to believe how he pulled that weight from only 60 Watts, but the facts are there; he obviously knows what he's doing as i haven't seen many of these type of home made LED setups that work as well as that but it looks like it works a treat.
I'm not here to start an argument, just think some of you are stuck in your ways not willing to accept there are more safe and efficient methods coming out that are coming close to yielding what HPS bulbs do. There we are... Flame me hahaha
