letsburn06 is right. One thing to consider.....most folks say when flowering, to use a three to one ratio of flowering spectrum bulbs to veg spectrum bulbs for best results.
ProGroWannabe Reviewed by ProGroWannabe on . Mixing Spectrum's Will mixing two different spectrum bulbs do anything wierd like cancel one of the wavelenghts out? I have added 3 42w CFL's at 2700k to my grow for flower. I am leaving 3 24w CFL's at 6500k in there till I can afford 3 more bulbs. Will the two spectrums interfere and should I remove the lower 6500k's or can they be fine togater and give my plants the benifit of more lumens? Rating: 5
