I got my 4x4 grow tent set up inside a dedicated room.
My 552m3/h extract fan pulls air from the reflector and out into the room where I got my heater, AC, humidifier and a dehumidifier set up. Right now my source of fresh air is two open windows but that wont work in the winter when temperatures drop below 0c, im looking to buy a air handling unit with heat recovery unit but I dont know how big it should be.
is there any rule of tumb for how much fresh air is needed pr square fot/m2 of growspace?
