...it's what I'm mainly running here, mesef. Just make sure your grow chamber doesn't get too much over 83f, and you should be ok (try fr 78 if you can)

My livingroom grow is a nice CFL based thingy, and needs way less ventilation (though it do need some)...

Just remember: 600w is basically the same as a good gaming PC, or entertainment unit, or a hairdryer at 1/3 power.

You should be fine.
