woah, this is impressive! @heatherrose, i am going to be spending so much time reading your previous posts today (LOL)

@jonpetrich, what do you think about this?

I am so excited watching the progress of this structure! I can only imagine how you feel!

I would love to have one of these some day!

It was an amazing process. We actually added a 2nd bigger one this year!

Oh now I am SUPER jealous... do you guys sell at farmer's markets? Or commercially?

We sell from the farm and at a farmers market.

This looks amazing! So much hard work, but it'll be amazing to plant in!

We will be starting the first of next year's seeds in only 2 weeks!

In only 2 weeks!? Yes! Can't wait to see pics of the sprouts!

What would you say your average low temp is there in KY? With the greenhouse sunk in the ground, I’m curious about how cold it gets in there?

This week has been 20° and lower at night (supposed to get down to 0° this weekend).

During the day, it can be 20° outside and 80° plus inside. Being sunken helps retain the heat we add via a propane heater at night.

We also use black barrels filled with water to absorp heath throughout the day and bleed it off at night.

Thanks, that's helpful. Our temps are similar. I've been looking into greenhouses and high tunnels and I'm trying to get info from people who have experience with them in climates, especially winter temps, similar to ours before I dive in!

Earth sheltered is the way to go. It made a huge difference in the amount of propane we used last year vs. the year before. So much that we built a 2nd bigger one this year (30 ft x 48 ft).
