Questions about metric tent sizes and the needed carbon filter

[Tomonaut]

What carbon filter and accompanying inline fan and duct should I take with a 100cmx100cmx180cm grow tent. Haven't found any CFM calculators that accounts sizes like this one.

If anyone has a set-up like this or has seen one like it could you help me out by linking it?


Thanks in advance. (Extra info: I plan to run a 600W viparspectra LED light)

Your fan needs to be able to vent your tent every min. Your filter needs to match or have a slightly better cfm raiting than the fan 100cm is just over 3 ft. Better the fan is to big than to small. So for easy math say 3.5x3.5x6
This mean you need an inline fan rated at 75cfm or better and a filter equil to or gerater than your fan but not more than double what the fan cfm is. Example say you chose a 100cfm fan the filter can be anywhare between 100cfm to 200cfm
Hope that helps

calculations are for nerds. You need way more than 100 cfm/ Anything from a 6 inch centrifugal canfan or vortex up to 8 inch on top of a 12-24 inch tall carbon filter will be adequate. Its better to go bigger and use a speed control to dial things in depending on the season. Dont use calculations as an excuse to go small. The filter is the most important part of a successful harvest. I would use a 6 inch centrifugal, on top of a high quality 24 inch tall 6 inch inlet carbon filter.

Good advice kinda lol i run a vortex sline myself... In a 5x5x7 vortex sline 6 in is 375cfm his tent is under 75cf. Thats changing the air 5 times a min. That is very hard on fan and tent unless you are running an intake fan also. The walls will be pulling very hard on the poles. Also since air is being restricted.. Laws of nature air cant leave the tent faster than it is comming in the tent which will stress the fan motor. Most 4 in fans run around 150 to 200 cfm. If the area is 75 cf and you need to cycle the air at least once a min. 200Cfm is overkill

I think I got it. I found a 187m3/h extractor fan of 10cm with a carbon filter of 175m3/h of course also 10cm. Is this good?

Fan matching the filter more cfm than the area. Yep it will work
