crossing over to the dark side

Hey RIU I have been compelled to begin my first real indoor set up(not just veg). I am an outdoor guy, but the elements, animals, temp, and prying eyes are beginning to give me headaches.
So... I found a nice 600 watt HPS cooltube, but I have ZERO experience with cooling, ductwork, etc... as I have always grown nature's way. Say that I am using a large cabinet instead of a room. How strong of a fan will I need to cool a cab with a 600watter. I'd like a constant 75 degrees F. Any one know how to help a bro out?

There are several things that will effect the temps inside that box. The first are the temps in the room that the box is in and is it climate controlled. I assume that you are going to use room air to cool that tube, not box air. How many cubic feet is the box going to be? I think that there are folks here willing to assist but, just need a little more information.

yeah,that^^

Making sure you have good air circulation is key to keeping temps low if you have no AC. Must haves are intake from bottom of cab, and exhaust at top. Humidity may be a issue during flowering so keep in mind you may need to leave room for a small dehumidifier. a 600 gets warm but my 400w MH gets hotter and my closet stays at 75-85.
Heres a good intake,,,http://www.google.com/products/catalog?q=dayton+blower&oe=utf-8&client=firefox-a&cid=3374130641325172329&ei=rgRPTOaENYzswQWXxbHcDA&sa=title&ved=0CA4Q8wIwATgA#p

I am thinking of using something that is 6 feet tall, 3 feet wide, and 2.5 feet deep. I may use something else tho if you guys think that will be a friggin oven with a 600

not sure if this threads still active but check out my cooltube thread, my temps are in control now.
