i tried going to the website and its under construction. have another link?
and for me i would only use LED lights for supplemental lighting. there are quite a few growers on this forum that only use LED's and there results are not bad.
if you do go led i would at least throw a few cfl's in the blue and red spectrum just to get a nicer light spectrum
i am happy with my hps but very curious about LED's as well.
plasma lighting is the new thing they are working on now. that will take a while so much $$$$$$$$ now.
anyway have another link?
