Low Grade Geothermal Heating and Cooling for Greenhouses If you’ve watched our most recent video, we interview JD Sawyer from Colorado Aquaponics at the Grow Haus in Denver, Colorado. We were down there interviewing JD about the work they were doing in the Denver community using aquaponics. In any case, we asked JD about the geothermal (Earth Battery) that had been installed in the Grow Haus. I’d seen it a year or two earlier when the building was still under construction, so I was curious about how it was performing for them. I was also curious because we have a small Low Grade Geothermal (LGG) System installed in our greenhouse. JD mentioned that it seemed to be working well for them, and when it had been running, I’d been impressed with the low-energy cooling capability of the system. What is Low Grade Geothermal (LGG)? For those of you who haven’t heard of LGG, it’s a method of using the thermal mass of the earth to both store energy (cooling; cycling hot air through to get cold ai Less
