I was wondering if you can flowers succesfully with CFL, if so would it take longer than HPS, Thanks,
i started out with two dual bulb 4' shop lights. added one more of the same and then when flowering started i added 3 100w cfl's (one for each plant), things are starting to look nice and sticky!
Hell yeah! You won't get as much bud as with a HPS, but get some big watts and position em right, and you won't be disappointed. Flowering needs red light, color temp 2700k-ish, or regular soft white. I threw in a daylight bulb too, for a little balance in the spectrum.
You can bud just as good with clf / flourescents as with HPS, as long as you have enough light. many has already proven on this forum you dont get Whipsy buds with flourescents when done the right way.
