The standard advice is MH is cooler/bluer and is better for vegetative growth
and
HPS is warmer/redder and is better for flowering and bud production.

You can gradually reduce the light but the flowering mechanism won't trigger until it gets at least 12 hours of uninterrupted darkness. I am unaware of any major benefits to gradually reducing the amount of light.

So I recommend HPS for flowering and just switch to 12/12 when you are ready to begin.

i wouldn't worry too much about the bulb. replace it within 18 months from now though. they only last for about a year before they lose a lot of lumens.

though they still look bright they don't have the same output.
