I think I overdid myself with a 1000w in a 6" in Cooltube in a 2.5x6x8 closet..

First time grow, thought I had everything right after reading for months, made one big mistake. Too big of a bulb (1k Eye Horti Blue), too small of a Cooltube, too small of a closet. I am wondering if I can get this done with my current bulb, or if my setup is just screwed and I have to replace either the cool tube or the bulb to a 600 (or if both are viable options). I don't believe my fan is the problem, I have a Can Max 6" connected to the tube blowing cool air through. My ballast is Lumatek dial-a-watt so I won't have a problem changing my bulb size, but would prefer to keep the 1k(unless this is completely going to overheat the whole closet) and just get a better tube. Thanks!

You CAN NOT put a 600 bulb in 1000 watt Ballast. just turn your Ballast down to low. Do you have ducting on the end of the cool tube venting out your space ? A digital/dimmable 1000 watt ballast will turn down to 600-400.

My ballast specifically says and has a Dial for changing the wattage, its one of the newer Lumatek. And no I havent bothered ducting the other side of the tube since I didnt think it would change anything (could be wrong). This is my ballast: http://www.amazon.com/gp/product/B007F3KSIY/ref=oh_details_o06_s00_i00?ie=UTF8&psc=1
