I am just about finished setting up my first grow room. I have 10 600w mh/hps lights with air cooled hoods. I have the lights in 2 rows of 5 with a carbon filter at the beginning of each row and exhausting the air outside. It is a 12x24 room with an 8ft cieling and I have a 3 ton A/C heating and cooling unit. I also have a 700cfm intake fan. My concern is that I live in a northern climate and when my lights are off the intake fan is going to be pulling alot of cold air (in winter months) into my room. Should I have the intake fan turn off when the lights go off? Won't this lack of fresh air hurt my plants? Also I am trying to find some kind of Hepa filter to put on my intake to keep out bugs, contaminants etc but can't seem to find one that would fit on a 6in intake ducting. Any suggestions? Thanks in advance for any input

you should use a air exchanger ...that give fresh air and keep the same temperature in the room area

You could also use a speed controller for the intake fan, so your oscillating fans would keep air from being stagnant. As far as hepa filtering for your intake, they make one for multiple size ducting. I use the carbon type for odor, but the hepa is Blue.

Yes get an air exchange. What I use as screens for my intake is your know the filters they use for heaters. It is really cheap and for a 6 inch intake hole I can cut four pieces out of it. i change out when it looks like it is needed.
