2200 Kelvin ? Is that the question? If so, use for flower. To Veg you want 6500-6700 Kelvin. Veggin under HPS will make ya plants stretch. I swear by T-5's for veg. Can damn near put on top of plants and dont need to worry about frying them. HID lighting for Veg is a waste of electricity in my book. But, you grow yer way, I grow mine.
