    Possible cooling/circulating thing for terrarium?

    Im looking into cooling my terrarium for neps and helis. im currently not getting the nice drop that im looking for, so ive been browsing and came across this fan.

    would this fan work if i ran it for a certain time period at night untill its cooled ? i know that this would mess up the humidity, so if i ran a humidifier along with this fan you think id be okay?

    More than likely the fans will lower humidity, if you supplement that as well then you will get some evaporational cooling

    Here is mine, but I run mine only when the lights are on. But as you can see my plants are very close to the lights (6 bulb T5)
    Without it I would have an oven.



    just my 2 cents based on my experiences, ymmv

    how do you achieve that flow of mist. you have a single fan, and then a humidifier feeding in ?

    yes, In my experience... keeping the humidifier external prevents a lot of problems and increases humidifier life (algae, bacteria growth... etc)

    Plus I'm constantly bringing in fresh air, then cooling and humidifying it.
    If you was to recirculate then the benefits are reduced as the return air's humidity increases. I have found it to be much more effective this way.

    The humidifier i use has a variable output, and its easy enough to find that "sweet spot" regardless of ambient conditions

    Not Mylar but foil covered foam insulation panels (home construction... cheap, easy to work with and efficient)

    I took parts of two of those racks and locked them together with zip ties to get one 2 shelf, 4' long setup... that way I could use standard 4' lighting

    I know it might be heresy but I've not really found the need to have a dramatic night time drop with helis. But then I dont have 85f day temps either
