Ya man your running 2,000 watts its gona get warm in there and humid too so your gona need fresh air intake and outake.
I had an 84 sq ft room a closet not a room and put in a 6 bulb 4 foot t5 and the first thing that happened was the humidity shot to 99% and the plants all got heat stress. So i had to go get an inline fan and cut some ventilation in there.
