    An Air conditioner cools by dehumidifying the air. Not exactly what I want. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img]
    Better would be a swamp cooler which cools the air by running it through water but there aren't any small models as far as I know...

    Best bet is an AC unit. You put some duct between the AC unit and the terrarium and hook the output of an ultrasonic humidifier into the duct before it enters the tank. Have them wired so the ultrasonic humidifier turns on when the AC is operating. This will rehumidify the air before it enters the grow chamber.

    During the cold outdoor months you can modify the system to just pull cold outside air through the duct and bypass the AC unit.

    Swords at www.jurassic-gardens.com uses this type of system. He might have some info on how to set it all up.

    What do you think about this one?
    It's a small swamp cooler + fan + mister in one.

    http://www.everythinghome.com/sumibox....+SF1510

    A shame it's just 5 cm too big in height and length to fit inside my terrarium. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_h_32.gif[/img]
    So if I were to buy it I have to redirect the air inside the terrarium.

    However I have no idea how much a swamp cooler actually cools in 'one time'. Because the cooler isn't in a closed enviroment... :
    The air only goes through the water once and enters the terrarium, which has to push out some other air into my own room again...
    Think it will work?

    I like your idea Tony. It sounds good in theory but have people actually tried it? AC air without the humidifier will probably harm the plants. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_r_32.gif[/img]
    Oh and do you happen to know a good online site to buy cheap/compact AC units? [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img]

    That fan thing is just a fancy ultrasonic humidifier. It will not cool down the air very much. A true evaporative cooler draws air through a wet pad/filter and some heat is transfered from the air to the water as the air evaporates the water off the pad and rises in humdity a little. Evaporative coolers generally give about a 10-15f drop in temperature depending on the pad
    thickness, airspeed through the pad and the relative humidity of the incoming air. This would be more like what you would want for an evaporative system. portable evaporative cooler

    Your correct about AC air being too dry to pump directly into a grow chamber. You definately would want to rehumidify it before it enters the grow chamber. The best way would be an ultrasonic humidifier between the grow chamber and the AC/cold window. A humidistat located within the duct can control the humidifier or it could be wired to operate when the ac/fan is functioning.

    The AC system is a bit more complicated and costs more in parts and energy use but would allow for a larger chamber and more cooling. I am interested in how well those portable evaportive systems work though ;>

    Here in the US small 5000 btu window AC units are all over the place in big discount stores like walmart etc.. usually around $100usd

    Tony if i had the room to build a grow chamber just for a bunch of highlands i would give it a try for you.........course if you wanted to donate a number of highlands i may be persuaded to get the EC unit and find room for a chamber [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_n_32.gif[/img]

    Thanks for your help Tony.

    The fan I listed does have some sort of ‘stuff’ which absorbs water so the air goes through it. (on the sides mostly I think)
    However I doubt it’s as effective as a real swamp cooler yeah.
    Just seemed like it was nice to have some things combined to save space & money.

    I have seen that one you listed before (or for that matter pretty much all related products on the site, I’ve been a busy bee these days trying to find the right products [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img] )

    It says: “Cools the direct air stream by up to 15 degrees” and “12 -15 degrees F of cooling power in air path”
    I guess it’s fair to assume that when I have it pump the air inside my terrarium (going in at the right side, air going out on the left side) the whole thing will cool with at least 10 degree Fahrenheit (5.5 Celsius)?

    Still it’s far from ideal I think.

    Do you know how much a compact (/cheap) AC unit can cool? (And I assume adding the sonic humidity won’t affect this much)

    hehe

    Just keep in mind the Evap cooler unit could not be placed entirely in the room as the high humidity inside would diminish it's effectiveness substantially. You would need to place the unit outside or find a way to get fresh dry air to the unit inside the room.
