idk guys... that one kinda sucks but i was looking at a solar tube that was "bright as the sun" designed for commercial buildings. i have no idea where i saw it for sale but i think it was in a little hippie store that caters to off the grid people. when i asked them how bright it was they pointed to a bunch of light fixtures in the ceiling and said "those are not powered.. it uses fiberoptics and a large solar collector... i will go ask around next time im in town...i also think it was like a couple grand!! not worth it for a huge grow but if you had the $$ and a small application it may work.. i will find it later..
lights coming on and i am working on transplanting
