150watt hps in a 30/46/8ft closet 3 plants to much???

I'm new to this indoor grow want to do it right.I have a 30/45/8ft closet thinking autoflower any suggestion on strains dat my do well and would I be asking to much to use a 250hps in such a small area considessring my aflow will only be a couple fans.Please all input is welcome.

I'm on my first indoor as well and I can tell you humidity is a MF. I think 3 is too many for the light. You are going to need to move the air around, no matter what you do. I recommend painting the walls in there with 1. a good primer (Killz), and 2. A flat white for reflectivity. Consider what you will be doing for the base/watering. I think a 125w hps is good for one plant and a your first closet grow. Good Luck!!
