Making the most of a small kit greenhouse in Colorado

I have an ongoing YouTube channel that follows the creation of a 4 panel polycarbonate greenhouse in Colorado at 6200 ft. To save time and effort (plus make it look nicer than my old plastic tunnel greenhouses) I bought a kit from backyard discovery and documented the enhancements that got it to holding an average of 22 degrees above outside temperatures when below freezing this last winter/spring.  At only 12 x7, this seems to be a good achievement for such a small greenhouse. Check it out at [youtube]https://youtube.com/@threeminutegreenhouse?si=Cp2a0uC_QITi53Q-- and let me know what other improvements I can try.  A bigger greenhouse is on the list but need more unshaded area to work with. The episodes try to stay around 3 minutes so a quick watch. See the lemon/lime and orange trees producing fruit!

Welcome to permies Bill and thanks for sharing your greenhouse success with us.

Testing

Here is going back to the beginning with the unboxing and build of the kit.
