I was never able to get my temp down to a tollerable level until I got a 5000 btu A/C for $99 at HDepot. I even ran a 350 vortex before for air exchange thru my air cool hood - still not enough. Now the room stays about 75deg lights on/ 63deg off and the more controlled environment has made for better more predictable growth. The fan on the A/C keeps the air circulated (plus a 10 inch desk fan) I replaced my vortex with a 170 that pulled air from outside the room into the reflector then out of the room. The A/C air stays in the room. WHen I open it up for gardening I get a new exchange of air in the room so it never gets stale. The difference in growth and bud quality was radically different at mid 70's. Before the A/C my highs were 95 deg.
The unit is extreamly energy efficiant and will take a load off your central air. My apt is usually around 80 -82 deg. I can imagine having to sit around in temps lower. When I bought it I was pissed to spend the $99 I did'nt really have - now I think it was the best calls of my grows.

ok im considering buying a 100 dollar ac unit my bedroom is about 20' x 20 ' and has hallway/bathroom about 3.5' by 20' will 5,000 btu be able to lower my temps enough without being run on full all the time
my centrAL ac in my apartment is set to 75 but my room is far away form it so it is like 80 in here

Run a duct to your window with that flex stuff for dryer attachments during the winter and have one vortex fan sucking in cool air and the other blowing the hotter air into the room. That way you could cool your grow area and at the same time heat your bedroom some.

you need more BTU than that, but you could just directly duct the cool air into the grow which should be more than enough.

Heres what you need to look at to figure how much BTU of AC power you need........................http://www.consumerenergycenter.org/...window_ac.html

Also don't forget to take into account that you don't really need to cool it that much, you already have central air so this is just supplemental, a 5000 btu one may just do the trick.

BUT for some of us we have to divert the whole central AC to the grow room to keep temps low, as it turns off when it gets cool in the rest of the house (and the grow room is already much warmer) what happens when it kicks off?

I use my central AC unit and I have to divert it all to my grow room it freezes the rest of the house, and here is winter.

Portable/window units are the way to go when you cant cool it any other way.
Later this winter I will b using a dry duct to drag in cool air, BUT what about right now?

My central air doesnt turn off very much at all during my lights on cycle to keep my grow room at 75-77

Honestly, don't you think that spending money on an A/C unit instead of your cooltube negates the point of having one? I have a 68" dual cooltube with 2x 1000w HPS bulbs in it and no A/C, yet I manage to keep my room at ~75°F. Your is a 400w. I would focus on getting what you already have to work instead of just adding.

Im no expert i but i think the cooler the air passing the bulb the cooler the air coming out on the other side will be
so if i'm cooling my light with 80 degree air say its coming out 85 thats heating my room even more making for less efficient cooling
the cooler the ambient air temp the cooler the light the cooler inside the tent itself

If you have any magical solutions to my problem let me know adrenaline

got the ac temps are topping out at 82 in the tent and the cool tube is within 20 inches of top of plants im going to try and get it a little closer but for now its straight
