Need advice on my setup.

First time grow. I'm about to start a 400w HID grow and because of some issues I've run into lately, the biggest space I have access to is 3.5x1.5x 4.5 to 7. It has a sloped ceiling, except at the top where I can hang the light from. My question is, how much is my grow going to be limited because of the small space, and what can I do to reduce the handicaps. I don't think i'll have a problem with autoflowers in the closet, but for full size plants, your advice would be greatly appreciated.

prolly run mostly indica,s, learn to lst, , low stress training, on you tube....peace

LST is the way to go
