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?
yeah you're gonna need thousands of those based on what ive seen grown from 5mm LEDs. granted you have alot of extras (CO2....) but its really a matter of photons generated getting to the plant. yes the xlamps are more expensive but with the time and labor put into mounting 1000's of 5mm, the heat they'll generate that you'll have to pay to control it seems like a wash.

Not sure about the color shift trigger as our plants are under a 5:2 ratio of red:blue 18 hour days and vegging like crazy

Please do make you're own lights:thumbsup: Wish I had the expertise to do that. Good luck cant wait to see your threadimp:
