Hey Everyone; I apologize for my newbiness, but I had a couple of questions. I know that for vegetating, a Metal Halide on 16/8 light schedule is optimal. I know that for flowering, a High Pressure Sodium bulb on 12/12 light schedule is optimal. My questions are: 1.) Can I vegetate with a High Pressure Sodium bulb on a 16/8 light schedule? 2.) Can I flower with a Metal Halide bulb on a 12/12 light schedule? I need to know whether or not I have to buy a 600W Metal Halide bulb to vegetate my clones for a week before putting them into 12/12 flowering. Thanks in advance!
