thanx for the help

That tent isn't big enough to make good use of a 600W light. You're better off with a 400W. You could easily fit 5 or 6 plants in there. Tents don't control odor unless you have an active exhaust with a carbon scrubber. You'll need it for more than a few plants.

well ive already got the 600w lamp now, will it stiil be good enough and will the plant grow well with it?

You can but I have a feeling your tent is going to have significant heat issues. A 600W bulb gets pretty hot. The other drawback for using your light is that you're using 50% more electricity than you need(a 400W light). Again, you can still grow some fat fucking nugs with your setup, just know what you're getting yourself into. You're really going to need a decent duct fan and an air-cooled reflector to keep temperatures under control, in my opinion.

well ive got a cool tube for it and a digital ballast, also im going to get a decent extractor fan. also how much electricity are we talking about with a 600w lamp, i live in student accomodation so i dont have to pay bills but they might get a bit suspicious if im using hell of alot of power

Can't really say for sure. I might pay more per hour than you do(or vice-versa), but I figure my bill is around $50 higher as a result of my grow op. Cost really goes up when I have to use AC in the summer time.
