Running your AC from your house, being sucked into your uninsulated garage, will not be cheap! e-l-e-c-tricity. I vote you run the scrubbed air back into your house via a floor register, that way, the house thermostat can get a feel for the garage and it's not just WASTING all that A/C. It's going to cost u like $250/mo in the summer if it gets to >85F if you leave it how you have it.

On a totally different note, I REALLY hope you UNPLUGGED that garage door opener lol....so you never accidentally open it...

o yea actually the garage door opener is on its own 15 amp breaker which im using for that sentinel controller. I think im gonna just get an ac unit. it will only cost me like 400$ and seems like the right way to solve the issues i'm having.
Last summer i shut all the floor registers in my house so that most the ac went into the garage. house wouldn't cool too quick like it usually does when they are open.

Scubbed air is going straight into the attic which has little holes on the siding and vents in the roof, i dont think there would be a way to get it to return into the house.

Does anybody know how much electricity a 12,000 btu ac unit pulls in watts??

I would disconnect the direct line to the A/C and use passive intake from a cool room in your house. Seeing as you can get to the ductwork this should be easy. You could as a suggestion connect your passive intake to a register in a room the is getting adequate cooling already. This way you set a temp controller on you exhaust fan which in turn will pull cool air from the house when need to cool the grow room. There are some other suggestions I have but this is by far the cheapest...

This opened my mind a little. I think its a good idea to have the passive air incoming from my cool house. however i dont think that connecting a duct from the room to a small register will be enough, also what would i do with the duct that is already connected to the register? I was thinking maybe I could just just cut a big hole in the door that leads to the garage, then maybe throw a air filter over it to block the light a little. then maybe hang a shower curtain in the doorway inside the garage to block the light a little more. What do you think about that?

cheap idea is to get a wireless thermostat and put it in the grow room if you already ran a duct there...assuming your a/c unit is decent you should be fine

also no need to run wires and you can run more then one thermostat

yea i cant really find a cheap wireless thermostat. Im thinking the new door with a hole cut in it to get the intake air from the house would work best. Just not just if ill run into pressure issue by taking air out of my house and not returning into the house

look on ebay...as long as the return for you a/c isn't in your room your fine

What do you mean by that? I would think that if the return IS in the garage then im fine. since im taking cold air from inside the house and returning it back into the house. But there isn't a way to return it into the house. Ill be using my 12" vent fan to pull cold air from inside my house and then blow it outside. I would imaging there being negative pressure in my house from me pulling the air out and not returning it. But with the negative pressure, would it mess up my central a/c?

Using my garage. I have disconnected a central a/c duct from one of the registers in my house, and ran it into my garage to add cool air. Next to where the central a/c duct comes into the grow room, I cut a larger hole that leads to under the house for a passive air intake. placed a 10 x 20 inch filter over that hole to filter incoming air from outside. I also have the exhaust vent fan hooked up to a carbon filter which blows through the ceiling into the attic.

Here are the issues i'm having, the central ac duct blows a/c in whenever the thermostat (which is inside the house) kicks it on. When this happens and the exhaust fan isn't on, it creates positive pressure in the room thus leaking the smell outside my garage.

On the flip side when the exhaust kicks on to cool the room, usually the ac is on also, and the cold air coming through the central gets sucked rite out through the exhaust.

Does anybody have an idea as to how to use my houses central ac and a exhaust fan together?

run the line off of the exhaust (carbon filtered) back into the house and leave it always running
