Full Version: Extraction
Hi all !!! Quick question,, would a 150mm ruck cool my lamp, and extract a chamber 3'x6'x6' chamber?
what lamp are you using
Hmm - it sounds a bit pokey to deal with that sized growspace, TBH; especially if it's on it's own and you're having to rely on passive intakes, as well. (passive vents should be 5-7x the area of the active one(s) for optimal performance)
My advice would be to try and make do with it if you already have the fan, but if you're going to buy one, I'd get a quite a bit larger one, or even better - get two - than your GR will have active intake and extraction which is ideal because you tweak it so as to maintain negative pressure, you know like when you open a door and it seems to resist your pull like the door's being sucked into the room.
When it comes to buying fans, it always pays to get the largest (sane) one that you can fit in the space - you can always turn fans down if they're too much, but if you end up purchasing a fan that's too small, it becomes a really expensive excersise as you'll end up wishing you'd gotten the bigger one which you'll end up buying as well.

I was trying to avoid that, but it looks like thats what im gnna have to do, so what sizes do u think would be best ? Im trying to build it rite the first time. I am planning on using a 600w cooltube.
