I've heard that Humboldt line more than a few times on these boards. That's wonderful if you live in Humboldt. In that case just stick to the method that works for you. Those of us with more significant limitations are looking for other solutions. I don't live in Humboldt so the pound growing in the forest isn't an option. I don't like the idea of a HID burning in my basement with my family asleep above or me away from the house. No thanks. I also have venting limitations that would present real problems running an HID. I'm not growing pounds for whatever use you put that to. I just need a few ounces per grow for personal use. If yield is off by a few grams do I care? No. If it takes a week or two longer do I care? No. Does it provide for me needs - that I care about.

Seems that many here tear down LEDs as though it is a challenge to their manhood. Get a life. If it's not for you so what? Walk away. Nothing to see here.
