A/C and venting air out, is it counter productive and how to find a balance

Title says it all guys, I have enough fans which are capable of moving the air in the room one a minute, obviously to exhaust heat and air for odor and temps. I have hps and leds so heat isnt a major factor but temps are really hot and dry now; I want to pump my a/c but wont I just be venting all that expensive a/c air? how do I find a balance? my exhausts are on the ceiling and the a/c is closer to ground level and there are many fans moving are around, a friend told me to exhaust at full capacity and run a/c on blast when its really hot. What are your thoughts? Thanks

bump? i need to know how to vent

How often do you exhaust? I've got mine running the entire time the lights are on, but my intake runs 24/7. If you don't want to run the AC all day, you can just hook up the AC to a reverse thermostat so that it only comes on when the temp reaches a set level, and leave the exhaust running all day to vent heat.

The cooler the air coming in, the cooler the tent will be inside even with exhaust running 24-7. I prefer to keep a stable temp outside my tent (ie the intake). But my tent is in my office so I need it a decent temp regardless.

I have an ac set on econo mode and a 4 in that draws thru a filter and both tents and vented outside. Keeps the temps in the tents nicely stabilized. Worth it in my book
