I looked at the procyone and the only reason I turned away was because of the price. The cree xlamps are very nice, but much more expensive than 5mm LED's. Especially now that they have the right wavelengths. The heat generated is also a big issue, but the grow light u have takes care of that. The other problem with the procyon is there are only 2 wavelengths, the other two (660 and 425) give many additional benefits that the plant could use. Ive also read you can trigger flowering by shifting the color of the lights from a majority blue to a majority red. have any of you heard of this?
