Heating a terrarium...and not the room.

Here's my situation.
I'm living in an apartment and the temperature is going to get down to around 0C to -10C. And I'm not going to heat it because I'm pretty damn cheap.
I plan to grow a nice little patch of 'legal' mushrooms for personal consumption. Nice little patch meaning an OZ+ so that I have enough to screw up making cubensis chocolates a few times.
I've only got one closet, so I'm going to devote a space 13in wide x 16in long x 23in high. Directly below it is a space of the identical size, as well. This can also be used if necessary (humidifier, heater, whatever).
My alternative space is too hard to measure, but it's inside the headboard of my bed. About 4ft long, 4 inches wide and 1.5ft high.
I'm not even sure where to start with this. I need something that won't light my bed or closet on fire, but it needs to keep my closet or headboard at a consistent heat all the time.
Anyone have any suggestions for me?

The big problem will be that if the outside air is colder than inside the tub, you will get lots of condensation which will fall on your substrate and that is not good.

Its not just that if there is condensation it will also lower the humidity of your FC.

I recommend a tub in tub incubator, look up one of the teks and invest in a submersible water heater--I have a 50 w but suggest a 100 w. Then you can either put the lid on at night and leave it off during the day or off the whole time...my roomies are cheap too and so this method has been working pretty well for me.

I would heat the whole closet / space so you have the same temp inside and out of the terrarium.

You can't grow in 10C temperatures, and the space you have is not large enough to provide air circulation, let alone heat safely. You'll either need to heat the entire room and spread your grow out, or wait until next summer. Good luck. RR

I realize that I can't grow at 10C, or -10C, but that wasn't my plan.
I also realize the problems with condensation and I understand why this would lower my humidity. On top of that, I understand why I can't use a dual tub method due to the fact that I still have problems with the top.
As for air exchange, that is something I can deal with. I've already devised a few strategies to get rid of that problem.
I'm thinking that heating the closet may be a good idea, or heating a large tub and having smaller tubs in it, then heat the large tub. I figure that would hold heat better and allow me to determine where the air goes in and out.
I will be casing and to minimize the amount of power used I'll probably be using perlite rather than a cool mist.
Heating the room is not an option because I've got three flat-mates (a guy and a couple) and the power bill is divided equally. If they decide to heat the place though, all this goes to scrap and I'll be growing like I've never grown before.

Yes I read the post and putting your FC in a TIT works quite well, I've had great success with it; its not super professional or awesome but it works! And worried about condensation? Try putting your FC at a slant, its so simple.

most people on here are against it but i got a modified warm mist humidifier connected to my terrarium. and it keeps it nice and toasty in there with little to none condensation.
