How To Heat A Greenhouse For FREE | Part 3

After burning my greenhouse furnace a few times and learning the best way to fuel it, I use my Seek Thermal Camera to measure the temps. Amazon Link: http://amzn.to/2HDUcX5

I waited for a cold morning to test the temperature ranges on the rocket furnace and earth air tube. I was happy to see the walipini trench and earth air tube both performing to raise the temperature in the greenhouse. The rocket mass heater did raise the temperature of the clay mass, but likely needs more burn time to have a significant impact.
