New ventilation for room and filter setup

[Jimboss83]

Hi gang just a bit confused researching this - was hoping to find a pinned post of a previous one but no luck

 

I’m looking at a new carbon filter and canfan fan setup for my grow room as I’ve decided to remove my tent cause I was sick to death of smacking my head on lights and snapping branches trying to get around them in late flower cycle as I had to have it in a corner restricting access....

So it’s approx 15m3 (3.8Lx1.8wx2.4 high) which calculates to 530cubic feet .... then I read you divide that number by 3 to replace air every 3 mins ? So u look for a fan which is 176cfm.... plus 20 percent for carbon filter so a fan around 200cfm ..

See I’ve already confused myself and I know those numbers aren’t correct haha

thank you

Max fan pro 150, blauberg 150 or any 6 inch would probably work but I'd go a bigger fan in that area and just run it less rpm.

Decent 6 inch mixed flow do 300cfm easy

 

I like max fan, the pro 150 is a great fan, tried a blauberg recently and just as good,maybe quieter.

 

Will have to check numbers, seems low for that area.

If was me i would go a 250mm fan and filter, you are better off with over kill rather then be under powered, the more air flow the better.

 

There is a saying a poor man spends twice and a rich man spends once, in other words go bigger rather smaller and have to spend again to get the bigger because the smaller dident cut it...

Agreed, plus if you have a 2 stage or fan controller on a big fan and if you get a big temp spike, wacking that sucker to max to bring down temp will serve you well

250 fan and filter it is ! Thanks for the replies ... would I allow the vacuum to draw air in out of the existing 125 intake or also put an inline fan and upgrade that vent to a 250 like the exhaust vent ?

So in a 8ft x 4ft x 8ft tent (256 cubic feet) a 200mm (8 inch) exhaust fan and filter should put me in good stead ? What do ya wreckon ?

Check the cfm measurement of the fan. And remember that some manufacturers tell fishing stories... always go much more than what you need. Its easier to let fresh air in than get hot stale air out.
