Sorry OP, was not intending on hijacking your thread.
Rob333, that grow was done by a respected member of our forums so far as I can tell. Thats also not the only side-by-side I can dig up. Its true HPS are cheaper, but LED has the advantage for stealth growers. Not to mention less power draw, and a *way* longer life.
You started talking about how LED cant hold up to HPS. I showed you different

change happens. Embrace it, it will be ok. Plus, LEDs will only get cheaper and better as time goes on.
Anyhow, sorry again OP. Just dont like it when people try to spread misinformation and then bail after they get proof put in their face. Carry on!
