Extractor fan power to run 2 tents 4x2

Hi guys does any one know if a 400 cfm inline extractor fan split between 2 , 4x2 tents both with filter in tent would be a nuff power

Depends what your climates like.
How much wattage your running in each tent.

I use less than that split between a 2x4 and 3x3 but I have a moderate climate and fairly cool grow room.

Give me a clue as to what temps your incoming air is and what temp your aiming for and I might be able to give you a better answer.

Hi thanks for reply my temp are pretty high at min with light migro 200 on between 83-90 on I live in Canary Islands so it hot here at moment , the room I have tent in was 87 today and inside tent was 90 that highest it ever been I supplement with a co2 boost everything seem ok tho as there growing well but obviously would like to lower if u have any ideas to lower that would be great , but back to my first question lol the 2 tent would be same size tent and same light side by side venting thru a wall about 6metres away , hope that make sense thanks

It's going to be tough to get decent airflow if the exhaust outlet is 6 meters from the tent. Maybe add a booster fan along the way but you really want much shorter runs to the exit point. If your source air is 87 you may be OK with co2 but I'm not an expert so see what others say about that.
