Red light spectrum

When growing with CFL's (they can produce good yields) even with 2400K the bulbs "lack" in the red light spectrum which help plant develop buds - Question: is there a bulb on can purchase that emits just "red" light spectrum?

Yes. Red LEDs. Get some all-red LED panels.

Red led are real touchy and need adequate chilling otherwise the red light output well go way down and your just generating heat these are the facts

it has to do with the cooling capability of the light ambient temps are important too but the fixture that houses the reds should stay as close to ambient to make it work while. Rather then finding a reliable fixture look into slapping a cob unit together like a 3000k Vero with some cheap pieces off eBay you'd bee very pleased i think

thanks for all information. Will start looking maybe be" 1,000 bulbs.com" might have them
