I have a 12' x 12' hoop-style greenhouse, and am interested in building a Rocket Stove Mass Heater for it (not to make it a hot house - just to try to keep things from freezing during cold spells). I've seen a number of videos of people building a RSMH for their greenhouse, but nothing about how the finished product works (or doesn't, as the case may be). I'd like to know if anyone has any first hand experience to share. Is this technology effective for this application?
