Ventilation Details!

[space81]

Hello,

I am setting up a tent with dimensions (4x4x6.5 ft) or (48x48x78 inches).
Light 600 W HID.

Question:
I am planning to install a 200 cfm rated carbon filter which should be enough for the room space, what is the suitable exhaust fan cfm rate? shall is higher or lower than the filter cfm rate?

thx,

Yeah I grow in the same size space and while is may be slightly overkill I run a vortex s line (great if stealth is an issue) rated at 347 cfm. I'd say you defiantly want to have a higher rated rate for your exhaust fan. I also use a variable speed controller so I can turn ventilation down when they are not in flowering. Well worth it Imo.

So what is the recommended Filter CFM & Fan CFM compared to the room size?

Isn't it big compared to the room size?

you can get as much cfm as you want but too much puts stress on the tent if yo don't have a proper sized intake.
