So What's the Stand on a Portable AC For Your & My Grow Room?

Green your idea might work these new portable ac units are designed to use in one spot and vent in different room, now that being said I don't know if the crack under the door can handle the volume the unit will put out but here is a low cost solution get a different door with the same hinge set up change the door do what you need to to make it work then you still have the original door to reinstall when your done with the grow room . also keep this in mind the amount of cfms a 6 inch pipe can move is drastically reduced at every 90% turn so try and keep it as straight as possible
 
Now that is a legendary idea!! It'd take a bit of DIYing, but it's definitely a superb solution.
I'm gonna consider that as a last minute solution. Thanks for sharing the genius bro. <3

Also, you rock for sharing that tip about 90 degree turns and cfms. I did not know that at all. Thanks man. :)
 
So my first try was kind of a success and a failure at the same time.
I hooked up the AC inside the grow room and linked up the duct with a bin bag underneath the door.
There was a clear struggle in terms of amount of air trying to make it out underneath the door. Looks like the space underneath the door might be just a tad too small of a crack.
Well, either way, the room temp started going down pretty quickly. I was happy.
I came back ten minutes later and for some reason the AC was just blowing warm air, and not cold air. As if it were on fan mode. Although I left it on AC.
Well needless to say, the room temp had climbed back up.

Not sure why that happened. Any ideas what might be the cause? =/
It was only a half hour try in total, so tomorrow i'm gonna try for a bit longer and see the results.

Most portable AC units have a temp sensor so the condenser shuts off to save energy once that temp is reached, the sensor is in the actual unit sitting outside the tent. Try setting your temp lower to keep the condenser on and cool air will constantly blow into your grow space. Peace!

FYI you might need to just cut a hole in your door!
 
BTW, just for the sake of ending this thread..
I know i'm a bit late, as i've been super lazy due to smoking..lol

But yeah, I ended up returning the unit and speeding up my harvest instead of combating the heat issues head on. The portable AC was a failure. Unless the hot air coming out of it is ducted outside of a window directly, it will do nothing in terms of cooling down the grow room.
So i'm gonna skip growing during the summer months, cause the heat would be too much to battle against.

Cheers.
 
I just ordered a refurbished single hose air conditioner/dehumidifier for $199 it will be here next week. Since I cannot vent outside the tent I have ran a 6" vent for it that discharges at my charcoal filter if needed I will add a small inline can fan as it's about a 14-15' run.
 
Hate to say this, but from what I read about the warming trend, it's only going to get worse. I really wonder what will happen to outdoor cannabis growing. And it will become much more expensive to grow inside. GreenArmadillo Why don't you just install an AC window unit in your grow room?
 
Yeah Alltatup before to long there won't be that many good places left to grow in outdoors, with all these changes taking place, in the future I bet autos, are gonna be even more popular. High as hell, just rambling
 
Getting a chuckle from each comment,I kept thinking about the closet door I just replaced.$19.00 at Menards $7.00 for hinges. Getting the chain saw started was the hardest part of the project.
 
I have the Della it works great but won't help the rh. Maybe a touch but the math theory is theory . Also have a dehumidifier and a sump pump to drain the water. The vent is hot hot. I run the hot air of the dehumidifier into the back of the ac then vent the ac out the ceiling. Works great but it does take a bit of cash. Temp 72 and rh 50 and I live in a swamp it's 100 percent rh outside and 90 degrees. Also the use plenty of energy so the electric bill will go up. Lights off during day for sure but make sure you can keep it dark for 12 hours for flower, no Leaks! I dont have a chiller though so that saves some money😀 good luck and happy growing
 
That's a fair point to be made about the whole issue of heat rising in general.

And btw the reasons I can't install an AC:

1) I'm renting this apartment, and have been told not to change a single thing within
2) My grow room is in a pretty small spare bathroom
 
Yeah man. If growing in a tent, then everything is A-OK, even with a portable AC. You'd just direct the cold air inside the tent, and get rid of the hot air in any way you choose.
I would have done this, but because i'm growing in a bathroom with a sink and toilet in it, I can't quite fit in a grow tent, haha. Too many odd bits and pieces sticking out here and there.

All the power to you bro. (Y)
 
Where the hell do you live where the humidity hits 90?? That's nuts mate!.
We get about a month of humidity here every year around August. Last week it felt like we hit 85% i'd say. Add 42 degrees celsius to the mix and it ain't no joke.
It's why I completely skipped growing this summer.
 
Now that my son is in college I would love to live in San Diego (weather is only better in like the Phillipines).
 
It's never less than 75 rh usually 90. It's 70rh in the house w the ac cranked . So my room was a big trial and error. That little ac does its job though.
