air con?

[greenmonster]

hi all,
i was wondering if anyone knew of any reasons for not putting an aircon or air-cooling unit in a growroom?
summer temps are a right pain: hard to keep it below 30C if it is 30C outside...
its annoying me with the doors wide open and i was thinking of getting perhaps a mini cooler or two to go in there, if i can find any! does anyone know of any places that sell them?
thanks 4 ur time.

MY ROOM IS 4' x 6' x 5'. I JUST PUT IN A 5000btu UNIT BOUGHT FROM LOWES FOR $85.00. WORKS WONDERFUL. JUST BIG ENOUGH TO KEEP THE TEMPS WHERE I WANT EM. I TURN IT ON AT LIGHTS ON AND OFF AT LITES OFF.

GOOD LUCK

Why wouldn't you be able to add an ac? I don't understand?

[greenmonster]

well Jdog: i had no idea thats why i was asking. Perhaps they make the air too dry/perhaps they remove co2 from the air/ etc etc, i was just being careful and seeeing if anyone had any bad experiences or knew of any reasons why i shouldnt use one. is that ok?

The small Ac's don't remove humidity, just keep it cool. I had to go get a dehumidifier the keep that down too. Our average humidity is about 60 to 70%. You need high for veg and low for flowering.

I believe AC's don't add anything, but actually removes the heat from the air..some people believe it actually puts "coldness" into the air. hehe i dont think coldness is a word but oh well

The cooler the air the more humidity there is.Cold air and hot air meet,you get what is called condensation.Water! Higher humidity!So you cool the light with a passive system using the AC In your home.Central heat and air.A four inch line blown across the bulb evrytime your unit comes on,would be a great way to accomplish 2 things,
1) Heat build-up
2)climate controlled due to the heat of the bulb,thus lowering humidity!

Oh I see.
Yes the humidity is the only negitive to using an AC.
But it's nt that bad.
My room goes to about 60 % so thats perfect.

The cooler the air the more humidity there is.
That's a little misleading- those are 2 separate variables. Given a certain level of water vapor in the air, lowering the temperature will cause it to condense.
This is the way that a still works.
Cool air can hold less vaporized liquid than warm air.

To demonstrate. Think of a day that is very hot and muggy. A cold front moves through, you get a thunderstorm, it passes. The air is drier. Most of the water vapor in the air has fallen out as rain.


I would advise someone using an a/c just to monitor the temperature fluctuations and try to keep the day/night temperatures within 15'F of each other. You can buy a thermostat-controlled plug that will switch the a/c on at whatever temperature you specify.

Yo Stinky! Your right on the money with the post! I was saying if you use an AC in the room,vent the light and room together as to run the air across the bulb to decrease humidity! You just don't know how many there are out there that don't know this! It is the same principles as above in your post! Only thing is the vapor that you would see after that rain,would be exausted by the fan!jdog sounds like you got a grip on it with the 60%!

Oh.. I was having a hard time following.
So you mean set it up so the bulb warms the air and excess mointure is then carried away... kind of like a hair dryer.
Gotcha.

[GaGrown]

That's The principle!Your on the right track,thinking that ! Good luck!
