👋 Heya, cfm is (cubic feet per minute) so it will be 2ftx2ftx6ft the height is included too.
24 cubic feet of space in your tent
Fan is rated to exhaust 110 cubic per minute.
What you want to do is create a negative pressure within the tent and set it to cycle on every so many minutes. The idea is to exhaust the entire tent in 1 minute or under and repeat this every 10-30 min depending on needs.
Your space is tiny so you would only need the tent on for 20 seconds before tent is completely exhausted.
Good luck.
