Geothermal Greenhouse in NW Missouri

A look inside a geothermal greenhouse

We know the owners of this geothermal greenhouse located in NW  Missouri and I get to go over and poke my head inside from time.  It seemed like a terrific idea and I was excited to even go watch it going up.

Yesterday we went by while we in the area to peek inside the geothermal greenhouse.  I was amazed with the progress of the plants inside.   These tomatoes, 5 different varieties if I remember correctly, were planted back in the first week of April.  They’re easily 3 times the size of my own tomatoes that are growing outdoors.

About this greenhouse

This greenhouse is a Mittleider design as seen in the Mittleider Gardening Course book.

Changes to the in garden greenhouse

Recently we made changes to the in garden greenhouse.  Arguable some of these changes are improvements.  They were all minor additions that didn’t add much cost to the project.  Ideally these changes would have been made and implemented during the build.  If you are considering building this I’d highly suggest altering your build plans to include these changes.

During our time with the Mittleider in garden greenhouse I’ve changed a few things about it and added my own personalized touches to it.  I’ve outlined these things in this little video we shot today.

We built the in garden greenhouse from the instructions provided in the Mittleider Gardening Course book.  We don’t provide a supplemental heat source to it, but are able to increase our growing season by about 6 to 8 weeks.   It allows us to start planting hardy plants 3-4 weeks before our average last frost of the year.

After the first frost of the year it also allows us to continue growing and protecting our vegetables by simply closing it up and protecting the plants from the cold.  On a sunny day we can easily see temperatures inside the  greenhouse rise 30 degrees above the outside temperatures.
