Hey guys, built a maze green house a few years ago, did the usual bubble wrap lining etc. And have been using an electric Amazon heater during winter with a controller so it stays between 10-15 degrees c
It's been doing the job keeping wifes tropical plants alive (only just with those temps) but I'm not enjoying getting $800 electricity bills during the winter months (I also have a large solar system so it would be even bigger with out)
What are some other more economical ways I can heat my green house over night?
Diesel heater a better option?
Some thing else ?
Any help would be appreciated.
