Mike,
Beautiful website and I love your greenhouse!
Did you use the Ceres Greenhouse GAHT plans (
https://ceresgs.com/climate-co...) or did you just design yours from research on the internet?
How deep below grade did you bury your gaht?
Great idea having a sink with drainboard right in your greenhouse.
I'm surprised you didn't insulate the knee wall for some more heat retention. Any reason not?
What brand is your greenhouse and what is the size?
It's a beauty, and so are your plants!
Jim
