Hi, I did some research on this subject but didn´t find info for small tents...

I'm setting up a DR60 (60x60x160cm) tent with a SS Led panel and the setup is almost done except for the carbon filter and fan.
The DR60 has 21 CF or 0,58 m3.
Considering that what would be a good CFM for an inline fan and whitch carbon filter size would be enough to control the odors??
I´ve seen lots of combos at ebay but most inline fans are at least 190CFM which I guess would overkill...
Would appreciate not only tips on the correct configuration but also where to find it in US stores. (I´ll be visiting you guys shortly!)
Please remember the fan+filter must fit the 60x60cm tent!

Thanks in advance and peace! :peace:
P.S. sorry for my bad English... trying to do my best as I´m from Brazil. Planning to do the first Brazilian journal to rollitup for this tent! :hump:

Thanks Insane! But is there any problem having a excessive exausting?

Stewart, fantastic DIY man! I will definitely consider this option! Anyway I´ll need a fan, and it´s hard to find anything below 100CFM. Would a 100CFM somehow be a problem ?? Cheers!

Not a lot of downsides to 'over exhaust'. You could produce excessive negative pressure & noise, at a higher cost. Most serious problems would arise when you have a significant mismatch.
I like a system that may be over designed that offer additional operating flexibility.
Please remember that your actual fan cfm will drop from its rated cfm due to the resistance from the carbon filter and duct work.
You can also use a variac controller to reduce the speed of your fan.

I have a 24 cf grow box, and I installed a can fan (rs4 @ 140 cfm) and filter (2600) with fan controller. This is a tight fit in a small space, but works for me.
This was designed to control odors AND exhaust heat from my a/c reflector. You have LED lights, so have much less of a heat concern than I.

You should try the computer fan/DIY filter for your setup, as long has you have the ability ($$$/time) to upgrade quickly in the future if needed.
