I thought about lighting, I plan on running LEDs, so not a lot of heat. Plus I am trying to avoid a huge temperature change at night.

I do plan on keeping the lid shut tight for most of the day, to minimize the evaporative losses. Opening the lid for an hour a day for gas exchange.

I was thinking I can kill two birds with one stone, by placing the mason jar on a heated turntable. Now will that create enough circulation? Allow for enough gas exchange? etc.

This will be an interesting experiment here in Alberta during the winter.
