Christine Circe	Subject: [Webinar Recording] Truly Passive Greenhouses by Paul Wheaton The problem: All greenhouses in a cold climate need heat.  So they consume energy and require human discipline.  At the same time, it is possible that on a sunny day, a greenhouse can get hot enough to kill everything inside.   The solution: Create a greenhouse that requires no heat, and will never overheat.  Mostly, we will use the heat from the summer to heat the structure through the winter.  And if we have a moment of excess heat we will passively store it and save it for later - with no harm to the plants, all with no need for human discipline. In this webinar, Paul discusses how this type of greenhouse is not only environmentally friendly, since it uses natural resources, but is also a cost-effective way to grow plants, because it eliminates the need for expensive heating and cooling systems.
