Solar Greenhouse Basics: Orientation

Solar greenhouse design begins with choosing the correct orientation for your greenhouse. For those in the Northern hemisphere, this means maximizing Southern exposure of your greenhouse. The length of the greenhouse (longer dimension) should face South as this is where the majority of light comes from in the Northern hemisphere. The North side of the…

Solar Greenhouse Basics: Insulating your foundation

Insulating the soil underneath your greenhouse is an essential (and easy) step for energy-efficient year-round growing. Here's the basics. Often when building an energy-efficient greenhouse, people think about solar greenhouse design with the right orientation and enough thermal mass. But they don’t realize that there is a whole lot going on underneath our feet. The…

Greenhouse Foundations

So, you want a year-round greenhouse?  Time to dig deep (literally). At Ceres Greenhouse, we design and build super energy-efficient, year-round greenhouses that are built to last.  We talk a lot about growing bananas, citrus, figs, tomatoes and other fresh fruits and vegetables, but we rarely “dig deep” to discuss the first steps of building…

3 Ways to Heat Your Greenhouse for Free this Winter

Learn how to harness and store solar energy to keep your greenhouse growing through the winter for free (or next to nothing) Greenhouses can be interesting environments to grow in. This is because standard greenhouse materials like glass and plastic (“glazing”) are extremely good at letting in light and heat in, and extremely good at…

Earth Sheltered Greenhouses

An interview with Mike Oehler, author of “The Earth Sheltered Solar Greenhouse Book” We’ve talked about walipini’s: underground pit-style greenhouses that don’t have a foundation wall or frame. Going a step beyond a walipini is a framed greenhouse built underground. A common design for these is often called an Earth-Sheltered Greenhouse, a term popularized by…

The Walipini Greenhouse Low-Down

I never thought I would be calling The Church of Latter Day Saints to ask about greenhouses in Bolivia. But, as with a lot of things when you start to dig beneath the surface (yes, pun intended; there will be more), you can find yourself in some surprising situations. The impetus for this article is…
