cfls for flowering??+rep

hey was up im not flowering my plant yet but i want to know if i can use 2 42 6500k and 2 30w 2700k???+rep thanks in advance

You can but the buds will be loose and crapy. Bare min you want a 250hps to get anything nice.

nah man im doing a pc grow??so should i get all 2700?

one plant? that should be fine.. as flowering progresses I move to a 3:1 27k to 65k ratio for more red/orange spectrum light, but yours will work just fine.

oh I don't care then.

so two 42w 6500 and 2 30w 2700 will work fine??

thts a total of 144 watts which is good enough for about 1 average sized plants. but the spectrum isnt. for every 6500k light there should be 2 2700k lights. infact i would buy 3 more of the 30 watt 2700k lights because there is 84 5600k watts and only 60 2700k watts. there should be a 2 to 1 ration on red light so if you got 3 more of the 2700k lights then youd have 150 watts of the right color temp and 80 watts of the opposing color temp. even though a 2 to 1 ratio would suggest 160 2700k watts, 150 will do. this will be more than adequate for 2 good sized plants. also, you should consider LSTing your plants to maximize yield because your using cfl's instead of hid's.

so i should get all 2700k for flowering can you answer like in simple words lol

yes, check the red link in my sig to see how cfls can work...
you want a mixed spectrum of light, even for flowering. During the first 2-3 weeks of 12/12, your plant will explode with growth and still needs some 65k light. After that I tend to go heavy on the 27k but still a few 65ks here and there... If you manage your canopy correctly and place your lights strategically, CFLs will do a great job. =)

alright man thanks +rep
