I've run CMH's, still have them. They are in my basement pantry.

Hope this answers your question. Not a bad light, just no noticeable boost.

Reptile UV lighting I've READ works just a bit and they are cheap.
 
They are supposed too give off uvb rays that can burn so the buds create more trichlomes to protect itself.blue metal halide.dont know what a cmh is.
 
Thanks for your response.I think iwill just stay with hps and led combo all the way through.dont want to mess any thing up now.:weed:
