I want to exhaust two tents, one 5x5x8 and 4x4x7. I’m thinking about using this fan, the 4 inch is 205 cfm and the 6 inch is 351 cfm. The lights will be 5, qb 120s in each tent and an additional 335 act. watt led in flower tent. So I’d mainly be moving moisture and CO2 not so much for cooling. These fans are supposedly very quiet and have a 12 foot temp/moisture probe that controls fan speed. What do you recommend? Also, suggestions on a carbon filter? View attachment 2701242
8 inch fan you can always get a speed controller . 8 inch centrifugal inline duct fan 127W 2500 RPM it will do both tents so 2 hoses in each tent 1 fan in a y tube if you will . i wold use 6 inch hose in each tent connected to this 8 inch fan .
I have 2 rooms with 2 fans and 2 controllers,I put a third fan connected to both rooms that kicks on for 10 min, twice an hour during lights off to keep air fresh, I tried doing 2 rooms on 1 fan,I couldn't get it to work,but I'd try Bryan O'Conner's idea,she looks great
