HPS is predominantly yellow-green spectrum. The least useful in the PAR(plant/photosynthetic usable radiation) spectrum. Though green *seems* brighter than red or blue(to us humans). See attachment.
Green leaves reflect(~75%) green light... That is elementary.

DUDE YOU WANT RED NOT GREEN OR BLUE SPECTRUM. now yes you can flower with a MH if you want. thats what the old timers used bac in the day, but never a green spectrum. if that was true then why put a green bulb in the room so you can enter when the lights are off, thats because that light spectrum has no or verry little efect on a flowering plant.

I agree. HPS bulbs put out predominantly green/yellow spectrum. According to you... HPS is unwanted.
Interesting. lol
Blue is still desired, as it's the most photosynthetic active region of the spectrum. Plus UV(below blue) is proven to increase THC production. Light from HPS bulbs emit almost an negligible amount of BLUE.

Use both 2700-3000k CFLs with 5500-6500k CFLs.

Perhaps you should measure the spectrum output of your HPS bulbs. HPS bulbs are around 2100K.
They spike around 560-580nm. This is the 'dead-zone' as far as PAR is concerned. To human vision, this is VERY, VERY BRIGHT.
