hello I was just wondering if anyone on here have tried or still us useing a rocket mass heater or wood stove for their greenhouse? Also how effective is it.. I'm planing to build one for a 20x100ft and 6ft high greenhouse with polythene sheets and also have propane heater as backup.
just watch out for rising Rh levels and that odd visit from the Pm angel..? running radiators of a wood burner would be a more even heat over such a large area good luck
