HPS are very good. The only problem is the heat they emit. If you have the airflow i would defiantly suggest these, better, denser buds. And the kelvins is just the spectrum, so 6500k for veg and 2700k for flower is ideal. It seams like you're a beginner so i think you may just want to go with some screw in cfl's from GE. just put about 8 on the six plants and get 27 watts for veg and 42 watt for flower.
hello guys... Thanks for comments ! I switch 18 h light period for 3 left plants .... 3 plants was males!...so i got few pix of them now...
