The previous post on the geodesic dome greenhouse outlined the logic in choosing a dome for this site and how it was by far the better option for fitting in all the things I wanted to have in this greenhouse. These include an aquaponics system and a bathroom as well as growing space for tropical and frost-tender fruits and vegetables, seed growing areas, a rocket-stove water heater and a worm farm – a fair bit to cram into an area measuring just 7x5m at the outset.

I also wanted to build in a subterranean heating & cooling system (SHCS) to make even better use of all the thermal mass present in the solid bedrock floor and back wall. This is a proven low-tech solution for maintaining comfortable temperatures and humidity levels in the greenhouse year round. It can minimise or even eliminate the need for supplementary heating or cooling.
