Thats not your Dads paisley tie. Its large frost crystals on the interior greenhouse plastic. Some crystals were 2 feet long.

Well it’s official… We now know what sub-zero temperatures will do to this bioshelter.

The morning’s outside temperature was -2 degrees

Inside the greenhouse
it got to 30 degrees

The soil temperature was 43 degrees

Wow, how amazing it is to witness the power of this greenhouse. With a thirty degree buffer from winter’s deadly embrace, all the plants should now be able to survive until spring. Even the hardy avocado and calamondin orange!

It will be exciting to see which plants will thrive over the next few days and weeks.
