Budhownd, you do know you could run a 600w in the space you have. If you got 2 fans running, one facing towards your plants and light and another facing an open window , and another one outside of your closet circulating cool-fresh air. This is only if you can keep your closet door open. If not, buy 2 portable fans and ductape them to the topleft and topright corners of your closet and run them when ever your light is on your plants.
