Umm,with that kind of lighting you're going to need sir conditioning.
I will only use the air conditioner during the plants night cycle. The Exhaust fan will be turned off during this time, and the AC will keep the room at 65-70 during the heat of the day, when all the plants are sleeping.
Running the air conditioner while the exhaust fan is running would be very inefficient, as the room is constantly dumping the air outside.
According to the first page of this thread,
"[FONT=Arial, Helvetica, sans-serif]
CFM = 3.16*Watts/deltaT
where deltaT = 10 *F
Intake Area = 2 x Exhaust Area"
If this is true: CFM = 3.16*4000/10 = 1264.
However, since my fan is 1050 cfm, it would be slightly more than a 10 degree increase. This still sounds very practical,seems like it would keep it from 65 to 75/77/78. With 5000w, I would need a 1500 cfm fan.
Am I out of my mind for thinking this?
