DIY Geothermal Greenhouse Part 4: Earth Battery INSTALLATION

#113 After starting to build our DIY EMT electrical metal conduit (“) greenhouse two years ago, we are finally completing the project. We readily admit we are not experts at this (we are not engineers, greenhouse experts, or thermodynamic scientists), but a family doing our best to do it all ourselves and install based on all that we have read or watched on YouTube (Don’t believe everything you see on the internet) to date and in line with our limited budget. Based on comments, we already know some things should be done differently. Hopefully, it still works well enough, even if not optimally. We plan to share the results regardless. In this video we are INSTALLING the passive solar geothermal earth battery system (or climate battery/thermal banking/ground to air heat transfer) after excavating 3,200 cubic feet of dirt from underneath the greenhouse with a Mahindra 3016 tractor. The idea is to use two high efficiency inline fans to pull hot air from the top of the greenhouse during
