Rusty... Very good points...I mean 660nm LED's are not cheap.. HID is a very proven lighting setup.

Most strains I've tried uv-b on has increased trich's but it's too hazardous for me and my uncle.. Then we seen clear inc's do a better job.. Finding out that clear inc's are mostly 660/730 explains our findings.. Until I smoked PAD med's I thought just like you HID was doing just fine... But after comparing PAD med's to a standard 12/12 HID med's, I can say there is quite a difference.. BUT yes is it worth the extra money/setup... I think for some it will be and for some it won't be.. For LED growers it will be a must..:thumbsup:
