ok this question might be dumb but how i see cfls with 42 and up with 2700 but what are the ones with 6500
metal halide for vegetative growth and high pressure sodium for flowering.I just bought a 400 watt mh/hps digital ballast package today for 300 bucks tax in.whats better metal halide or sodium?
If i was going to go the whole growth with a hid system i would use a high pressure sodium bulb because it will produce way more bud then a mh bulb during the flowering stage.Let me ask this then scene there Autos do i have to change the lights or will the metal halide do for the hole growth.
