It is an interesting problem. I have questions after thinking about it more.
What are you using for your media? Soilless media would be sterile, until you open the bag of course. Raybo's 3-2-1? Something else?
Aq Heaters - the more expensive ones are either thick borosilicate or titanium. Some come with sensors that shut off when dry. That would seem to be a required feature for an earthtainer application.
Plans for auto watering system?
If you go the heater route, how many earthtainers are you willing to commit the 1st year?
I would think that a temp setting of around 60 at night would probably do the trick. You only need to keep the 'tainers above 35 at night.
What varieties are you planning on growing?
All in all I think it would work.
