Timeing for fans ??

So, right now Im running my fans 24hrs a day. I have 4 fans total: 2 circulation, 1 intake and 1 exhaust. Am I just wasteing energy Can someone tell me what timeing they should be on

i would have the 2 circulation on while the lights r on, and with intake n exhaust u dont want them on together, u want ur intake to bring air in, let that air stay in the room for about 30min, then have the intake go off and ur exhaust go on for like 5 min make the air exit, then have ur intake on again. and repeat.

You can run them 24hrs if you want but they don't really need all that circulation wen the lights are off mabe you could run only one for circulation wen their sleeping

yes he can run them for 24 hrs, but he wants to save as much electricity as possible, so i would have them go off as much as possible, and yea u don't really need any of the fans on at night,its just overkill and ur plants don't really need the airflow at night, except for maybe the exhaust fan for like a couple hours to get all the old air out, and when the lights turn on have the intake bring in new air and start ur cycle

Thanks alot!! I think I'm getting the hang of this shit, so much to learn, so little time !!
