I'm thinking of building a 16X25 high tunnel. A small stove in the middle would really help out on the cold Tennessee nights and days.

I have a 30 gallon steel barrel to start with and access to a really big scrap yard. Must be on the extra cheap.

You might consider making yourself a thermal mass rocket stove. Those are pretty cool.

My first thought was what is your greenhouse going to be made of?

This is awesome! I think we need to make one for our greenhouse. I'm going to research this right away! Thanks!

D of d I'm going to put a 10'X10' section of metal roof with the stove pipe in the middle.
