    i got mine from petsmart. the clerk said they didn't sell it, but after a brief search, i found it in the reptiles section [img]http://www.**********.com/iB_html312/non-cgi/emoticons/laugh.gif[/img] . i believe you have to turn it off once in a while (like every few minutes) to avoide overheating of the tank.

    Jmenprkr,

    Buy an aquarium at Petsmart or a garage sale. Buy the fogger from Ebay. Buy a little computer fan at Radio Shack. You can buy a cheap timer from Home Depot or Target. Get the PVC pipe at Home Depot too.

    You can get any of that from a lot of places, not just the ones I mentioned.

    UPDATE

    Now that several days have passed, i checked my readings after a 1 hour ventilation cycle. I am suprised that my humidity levels have risen quite a bit!

    After 1 hour at night:
    humidity in the upper terrarium was 97% instead of the mid-80 range.
    humidity in the lower terrarium was 94%: much higher than the 70% range.

    The temperatures in both tanks were 2 F less than ambient room temp. (room temp = 73 F)

    So what happened? The water level in the 5.5 tank has been decreasing over the past several days ( I have yet to refill the tank ), and now the fogger is working more efficiently with the lower water level.

    My point You can adjust your water level in the small tank to bring about desired humidity levels in your terrarium(s).

    I could be all wrong, but I think I'm onto something here [img]http://www.**********.com/iB_html312/non-cgi/emoticons/biggrin.gif[/img]

    Homer,
    You are very correct in assuming that less water means the fogger works more efficiently. I find that best fog from an Exoterra fogger like yours is at about 2 inches(+/- a little). I would love to see a picture of the system at startup, and then maybe an interval or two, then after the full hour... This is very interesting indeed!! THANKS FOR SHARING!!

    As it turns out my fan runs on AC current. I guess I got lucky when I picked it up from a demolition construction site I worked at last August. My fan is old-school. Made in West Germany, but it works like a champ. Good German engineering is the key it seems.

    I do have 12v DC fans at my disposal as well. I'm working on creating a peltier system and am trying figure out how to plug them in myself. So far, I'm planning on hooking them into an old PSU (computer power supply). The trick is to get the PSU to think its connected to a computer, until then it (psu) won't turn on. Casper knows exactly how to do this...

    So, goldtrap2690, get yourself a ATX PSU if you don't have one already, and hope someone tells us how to get it to "fire up" w/o a computer present.

    Could someone please post a reply and let us know how to do this? [img]http://www.**********.com/iB_html312/non-cgi/emoticons/rock.gif[/img]

    Hi Homer,
    I just finished work on a peltier system of my own, you should check out the thread: Electrical questions for several posts by casper. I am using an old (AT) architecture PSU, and it works like a champ! GOOD LUCK!!

    I replied to Homer in an E-mail, but for anyone else wondering how to fool an ATX psu to turn on without being hooked to a computer here it is.

    On the ATX connector (the longest one that connects to your motherboard) you need to jump the green wire with a black one (green = PSU on , Black = ground) there is only 1 green and multiple black.

    You can either use a paperclip and jam it in the holes, or you can simply cut the wires and splice them if you don't plan on using the psu for anything else.
