I've been having a hard time maintaining an adequate level of humidity. I live in the Canadian praries and this time of year the air gets really cold and dry, so, in order to keep it warm for her, i have an under tank heating pad and a red heat lamp.... i've insulated the entire encloser with that black on black core foam board ( as well ive used the foam board to section of my tank as it is way too big for her now) i sealed it with black electrical tape and duct tape. i also did the whole 3 layer of tinfoil over the lid. i dont have the heat lamp completely over the encloser as it gets too hot and sucks every bit of humidity out, i leave the lamp about 1/4 to 1/2 way directed into the tank the rest is over the tinfoil..... at the moment the humidity is 37, when i mist it shoots up to 80, then after 5 minutes or so, its back down to 45-ish and keeps on dropping..... i dont want to mist all the time to keep it up, as ive read all the bad stuff that could cause.... i was in the proccess of making her a little humid hide for when she goes into shed, when i thought of something.

You know that floral foam stuff you use to keep flower arrangements in place, and it REALLY holds moisture... well, what if i placed that in a plastice dish with moist or kinda damp paper towls on top? would this be a good idea, or foolish? i dont think there's anything harmfull about it, but im not sure...

As i've pretty much learned all that i have from this site, and trust that many here are very informative and honest....i figured id better get the go-ahead from people who know what they're talking about.

Any help here would be greatly appreciated!
