Last two days I have experimented with the west vent. When the sun is going down it is staying open to long for the winter time. So I have disabled it before it before it lets out to much warm air.
The green house has stayed 3 degrees warmer the last two nights. It has not going below 56 F.
Here are the plants.
I thought this looked cool Google caught my greenhouse being built. I am sure the tax man will use this against me someday.
In front of the green house is where I was painting the 2 x 6 rafters you and see the painted and ready to go up. Right by that is my chop saw table.
