The Truth About Walipini and Geodesic Dome Greenhouses

There are many different shapes and building styles of passive solar greenhouses. The most successful building styles (commonly referred to as “geometries”) integrate four basic principles: orientation, glazing, insulation, and ventilation into an energy-efficient grow solution that can perform year-round. Two common solar geometries, besides Ceres’ standard greenhouse design, are the walipini and geodesic dome…

Quality versus Quantity – Which is More Important for Greenhouse Lighting Optimization?

Developing a greenhouse lighting strategy for your grow operation might seem overwhelming. How much do I need to use greenhouse supplemental lighting? Does light intensity matter? What about the light spectrum? In this blog we will break down some of these complex questions. Specifically we will address: Defining quantity of light Photosynthetic Photon Flux Density…

6 Common Greenhouse Pests and How to Manage Them

Pest and disease outbreaks in a greenhouse are a serious pain and can get out of hand if they aren’t addressed properly. Because this is such a prevalent issue within the greenhouse community, we’ve created this article on how to identify and manage 6 of the most common greenhouse pests. But before we get into…

Choosing the Right Angle for Your Greenhouse Roof

Finding the best angle for your greenhouse roof is not as clear cut as some solar greenhouse designers make it sound. Solar greenhouse designers often cite this rule of thumb: To find the “best” angle (or pitch) for a greenhouse roof take your latitude and add 20 degrees. While the logic behind this rule is…

What Is An All-Weather Greenhouse?

As much as cultivators wish they could predict what their outdoor growing season will be like, they are always at the mercy of Mother Nature. Whether it’s an early freeze, smoke pollution, drought or hailstorm, extreme and volatile weather patterns are becoming more frequent and are an increasing threat to our crop yield and food…

How Do I Control Humidity in My Greenhouse?

Managing and balancing temperature and humidity in the greenhouse can be a source of frustration, further compounded by location, climate, greenhouse environmental control systems, and crop choice. Before considering options like venting, humidifiers, and evaporative cooling walls, it is important to understand relative humidity and its relation to temperature. Once this is understood we can…
