Agreed HPS (High Pressure Sodium) for flowering. MH (Medal Halide) has a blue spectrum that is good for vegetative growth.
MH or HPS can be used for for both vegetative growth and flowering growth.

Local growers in my area say vegetative growth under the HPS makes some kannibis plants vegetative growth stay shorter and bushier then if a MH is used during the vegetative growth.

Good Growing!
