Hello everyone. Long time reader, first time grower. (All legal of course). I'm in the process of setting up my flowering room. I am growing in a GL80 tent. I have a 400 HPS I'm planning on using for the space. I've already set up a carbon scrubber to keep down the scents as well as vent the room. For that, I am using a nice heavy duty fan (around 200 cfm). I got a great deal on a light system that is not setup for air cooling. I realized, after I set everything up - that my 400 hps was putting off a bunch more heat than I thought it would. I've gone back to the drawing board - and am spending the extra cash to get a 4'' sun system air-cooled setup. In regards to my light setup - I have a question about the kind of fan I should use. Should I go ahead and spend the extra 80-100 bucks on another powerful fan for the light cooling - or should I just go with an inline duct fan. I'm not exactly sure how much 'punch' I'll need to keep the light cool. In other words - what kind of fan would you use in my situation? Any advise would be appreciated. Thanks!
Just a bump. Still looking for any advise from wise growers out there. for a 3' 3' 6' (almost) growing space with 1 400 HPS - what would the best fan be for the light cooling?
I've been thinking about it - and I suppose the better fan I get, the more cooling power there will be for the new reflector w/ lens. Should I just get another powerful 4'' fan?
Really?!? any 4" inline fan will be just fine to cool the light, you can throw it on a controller too and you can control your temps a bit too if you wanted.
Thanks for the answer soapman - that's what I was getting after. I know they make inline fans of different strengths and I wanted to make sure I didn't need to get the 200 cfm fan in order to keep the light cool. I'll probally just go ahead and get a 30 dollar inline fan. That should do the trick. I'd be pushing the air through no more than 10 feet of ducting all together.
