A high tunnel is a unheated greenhouse that will allow us to get an early start on heirloom tomatoes and extend our season into the winter. We went with a 30′ X 96′ gable style structure. The process has been slow in putting it up because this is the first time I have built one. Our construction began after a bit of head scratching and double checking measurements to make sure the ground posts (basically the foundation) were square.  We had to borrow scaffolding from a friend to be able to raise the hoops and decided to place it on a hay wagon so it could be moved easily. This system worked until we had a beautiful day and our portable scaffolding got stuck in the mud! We are about half way done and look forward to growing in it this season.
