Hi everyone! So I have my PDC but haven't been able to personally use it for myself until now. We are on our land at 9300' elevation and about to put in a greenhouse. We hope to use the earthened shelter concept from Mike Oahler (if I spelled his last name right), and also use the heat tubes for some geothermal warmth. We hope to have both annual and perennial vegetation along with a few trees. Please share your thoughts and ideas for this newbie. I would love to hear any of your suggestions as we are about to start the build in the next few weeks.
