Heating multiple enclosures

[J.mena]

So I have been thinking of ways to keep all my individual mantids warm. I thinking of getting a portable green house with those plastic covers. So I can heat all my deli cups and tanks or whatnot. Just can't decide on how to warm them.

What do you guys use to keep all your mantids toasty through the winter. I was thinking of running heater cables throughout the shelving of the greenhouse. Are there easier ways to do that?

You could find an old refrigerator/freezer, strip out all the unnecessary parts and convert it into an incubator. It won't give you a nice view of the mantids but it will work. If you wanted to get fancy and have the money you could make a glass door to go on the front.

So I decided on getting the green house and running heating cables through the shelves. Hopefully it works out. Couldn't really find any other options.
