4 season greenhouse 2 weeks at -24 to -31 Celsius, gas and electricity consumption

In the video I say 13 days but it is actually 14... ooops. Anyway. 6.3 gigajouls of natural gas consumed in 2 weeks during albertas cold snap of -24 to -31 degrees Celsius. Electricity was about 950 kilowatt hrs. I think this is very reasonable. Mostly, I’m happy the greenhouse didn’t only hold up to the frigid cold but the gardens did very well over that time.
