i would def vent the light. my plants can touch the glass of my hood and i dont have to worry about burning cause mine are vented. if you do the same u should be fine. 40 inches is pretty damn small tho. think a foot for the light at least and a foot for the pots, and then another 6+ inches for the tips to be away from the lights that only leaves u with 10 inches to grow.
