Heating for silkworms?

[IndigoBlue]

I'm planning on raising silkworms and well, for the first stage of their lives, I will have an incubator to keep them warm. What I'm not sure of is what is a good way of providing heat for them when they've grown bigger and are no longer living in the incubator? I'm just thinking it would be better to provide SOME heat, since I read that it's optimal to keep the temperature at 78-88 F for them. My house is only 70 F at most at this time of year. However I don't want to also dry out the food quickly from the heat source. Anyone have any experience with this?

I raised silks from eggs with no heating, not even an incubator since it was summer when I hatched off. 70 is a little cold, however anything around 75 should be fine. 78-80 degrees c. is just for optimal growth rate. I haven't read of any who use heating after the incubation period.

I thought 70 would be a bit cold. That is why I'd like to provide a little bit of heat. What would be a nice and easy way of doing that? Or would they be able to survive just fine without any, even for breeding; just that it would affect growth rates without being detrimental in any way?
