Hi there. I'm flowering under a bunch of fluoros and, a 250 watt Metal Halide fixture, and a LED UFO.
Which buds are growing the best? The ones under the LED UFO. By far, they're doing better -noticeably- than the other buds in the closet.
That said, I got mine off Ebay from an importer for way cheaper than the name brand. Make sure that you get the right wavelengths though. Some cheap knockoffs won't have optimal wavelengths.... I believe it's 460 and 660. Oh, and it's only 90 watts, doesn't overheat like the MH, and has the combo of both red and blue.
