New room set up for indoor

Hey yall!
Ive been working hard to create this room, before it was just some lonley corner with insulation. I put down some floor boards and hooked up a home made ventilation system (hopfully it will work). I also have 48" Florescent cool-whites as my light source. I plan on adding another 48" as well as putting reflective insulation on the left (where the insultion is primarily exposed). Im also going to put in another fan for the wind simulation. Under one light i plan on having 4 autoflower plants, could i fit more under there? one problem is also the height of the room, it is only 40-30 inch high, which could come as an issue. Also, i need some way to block out the light, is there some sort of light absorbent felt or curtain i could put up??? Other than the fiber glass from insulation, the air quiality is fine, its at a lower normal humidity rate and the room is always on the warmer side.Tell me what you think and maybe some suggestions. Thanks!

Waiting on some replies :/

Box a smaller part of that space off, so you have no way of light entering, that way you can also use a reflective substance on the walls, fit a fan in there somewhere to keep temps to a suitable range, what autoflowers have you gone for? Did you review the strain first, that way you could see average heights etc, take a look at some grow rooms throughout here, plenty to get ideas from, best of luck fella.
