A question for passive storage afficionados
So we had zero degrees this morning. today it is sunny and 42 degrees. Sunday it will be 66 degrees and sunny. If it were any warmer today, for the health of my plants I would have to ventilate...on Sunday I'll have lots of windows open. Why would I want to hold heat inside the gh hoping that my solar devices will soak it up while leaving it a decent temp for my crops...spinach doesn't like 85 or 90 degrees. For me the crop comes first and I have to keep good temps both high and low?
