Yes I just harvested. I have been amazed once again at how much goes away when the water inside the plant tissue goes away.

I too have always bought this light becuase it is said to be the best. I think you usually get what you pay for. I would be interested in documentation however, showing side by side comparisons with less expensive brands. Is the extra cost really made up for in the yield? Probably so, but who knows...?

I buy mine at the hydro store and I get ripped off. I think I pay $115 for a 600 watt, but they always have them.
