Geothermal

The interesting thing about this is that it can save a lot of energy.  The theory behind it is that the ground is a constant temperature once you get down deep enough.  In this video, he talks about going down 8 feet.

Once upon a time, when the idea of going off-grid was new to me, I thought about burying a conex down underground.

Seems like I might have been on the right track as far as climate control is concerned.  A conex can be bought for a couple thousand dollars.  Just dig out a space deep enough, and plant that sucker.

But let's get real.  This is only about applying geothermal for regulating temps in a greenhouse.
