Ok here is the deal, my grow room gets to hot, My lights are ventilated, and I also have a couple of fans to blowing in and out, but since it is summer my room gets just a little to hot, but there is no way to enough cool air in their from my central A/C...............so here is question, Is their any type of potable A/C that dosent need window access, I have seen the ones that arnt window units, but you still need to vent it outdoors through ducting, I don't have that option because my grow space is some good distance from the window, and my complex dosent let you have window units...do I have any A/C options

all ac's need to vent. you can vent a portable ac to your room and let your central ac cool the room. you can try a miniture swamp cooler but it will mess up your humidity.

how hot is that exhaust air could I just exhaust it into my place? I already got my central A/c kicking to cool the grow space but its not enough

I posted that before I saw oyur post, thats what I thinking because my light already puts off alot heat (400w,600w) and I have them vented into my bedroom via 3 200cfm can fans

Cut a hole into the attic and vent your lights up there. That will get rid of allot of your heat and probably solve the problem.

I have done this even in on the bottom floor of a two story complex.

first of all, nice setup with the lights and it looks like you are making awesome progress. as for the a/c i just purchased one that is vented via the window, but doesn't stick out of the window like a traditional unit.
the picture i have attached shows the only part of the unit that stickes in the window. a piece of ducting then fits into the hole and help vent the portable unit. extensions could be made to some type of ducting like this. it cost about 300 and got it from home depot.

or you could put your exhaust in the return lines of your a/c assuming you have some sort of carbon filter on them.

Bong surf how hot is the exhaust that is coming from your A/C, do you think I could just vent my exhaust from a potable A/C like yours into my bedroom and than cool the bedroom via the central A/C....because I already exhaust the hot air from the lights into the bedroom, and it stays relatively cool in the bedroom via the central AC

seems like you;ve asked this a couple of times without an answer. i;m going to do my best to help. the answer depends on your particular circumstances so all i can do is give you things to think about to help you.


i use a 12,000 btu portable ac and vent it to my garage. the vent seems to give off as much heat as it cools, which i believe is actually a law of thermodynamics but high school was a long time ago.

so your question is can the central ac handle this extra heat - and the answer depends on the capacity of your central a/c and the outdoor temps. if your central ac is working too hard to keep the room cool it won;t have the extra capacity to cool your exhaust air.

my best guess is your central ac will handle the load but your electric bill will go up by twice the amount of electricity used by your portable ac.

the exhaust is pretty hot actually.... what i did is cut a hole in the wall and hooked the exhaust right into the wall. You will have a little drywall to fix when u leave but it is pretty easy. I could add pics if u'd like....

you just exhoust the hot air into the wall, dosent that air have to go somewhere? where does it go? I live on the second floor apt, but i wouldn't have problem cutting a hole in the wall, I could just spackle later, as long as it works.......I'm just wondering where that hot air goes, i don't want a problem where my neighbors have hot air coming out of their light sockets and shit lol...that sinks ships you know...................the guy said earlier that you could vent it into the ceiling.......I thought about that too.........and I was thinking my bathroom vent goes into the ceiling to so that air has got to go somewhere, and i doubt if it is ventilated all the way outside since i live on the 2nd story of 3 story, so if the bathroom vent is just ventilated to ceiling and not directly to the outside, I should be able to do the same with an A/C in the wall like you said or in the ceiling......I think I'm going to take a look at my bathroom fan vent, take it apart and see what the ceiling looks like up there, see how much space inbetween floors ect.

i would think that the air would go up thru the wall into the attic area(or in between floors). The wall gets a little warm but not hot.

if this can work it would make my life so much easier because right now I have to have the door open with fan blowing straight in their plus all the ventilation, I have this bright ass light shooting out of my walk in closet, and a bunch noisey ass fans, subsquently i don't have anybody over to my place
