I like Metal Halide for flowering. I quit using HPS several years ago.

Dual 400 CMH (ceramic metal halide bulbs) 4000k.
Metal Halide bulbs are available in Kelvin temps going from 3000k to over 7000K
I like 6000k-7000K for vegging - 4000k for flowering.
HPS kelvin temps are pretty much just 2100k to 2700k

(I'm in HPS rehab:jointsmile
