colored florescent sleeves ???

does anyone know if theres any sleeves out there to turn normal florescent bulbs(4ft or 8 ft) into the proper color spectrum to promote growth or flowering ? ---maybe a cheap way to pick up fixtures people aren't wanting anymore and using crap bulds & yet still have the proper growth colors --then swap plastic tubes for the flowering stages :)

Light is a pretty complex issue. You can do an awful lot of research on light, and not know a fraction of what there is to know.

I would suggest reading up on Photosynthetically active radiation aka PAR, Light temperature. and luminous flux.

COB LED lights are what's happening now. And not terribly expensive. Last 50,000 hours.
