actually your right about both spectrums being best for flower but both spectrums in the same output valocity in other words using a mh and a hps would be optiomal using mh for flowering isnt unheard off as mand has said(hello temptress) BUT for flowering purposes hps's and cfls would make much more sense then mh and cfls..if its not to late maybe you should look into a switchable ballest which can be used in conjuction with either mh or hps bulbs...
BkSkillz Reviewed by BkSkillz on . MH & CFL for flowering? im going to have a few plants going into flowering soon and was wondering if it was okay to run MH while flowering? i will also be using CFL rated at 2700K for the red spectrum im thinking about running 400 watt MH light, and approximately 6-8 CFL putting out 130 watts each you think this set up will be okay for flowering? thanks Rating: 5
