By Hervé Maumus-Hue Managing a perfect growing environment is challenging and is the topic of much research. We know that the environment dictates the efficiency of these chemical and physical processes/reactions. As shown below, the environment can be divided into 9 main parameters called the nine cardinal parameters: CO2, temperature, humidity, light, wind, oxygen in…
What is QbD? Quality by Design (QbD) is a design approach with a focus on building quality into the original product. A product can be defined as a good, service, information, or an internal process. The QbD process is organized into five major steps: defining the objectives and goals, the discovery of appropriate data, design,…
At Ceres, we help our clients become smarter growers by staying at the forefront of greenhouse technology. We conduct our own research on greenhouse systems and collaborate with research institutions so we can continue to optimize our structures. The following is an overview of Red and Far Red light radiation and its effects on plants.…
Are you spending too much on energy costs? Now that we’ve covered how greenhouse design can save you on lighting costs, and the pros and cons of HPS and LED lights, we’ll discuss how you can increase lighting efficiencies in your commercial cannabis greenhouse with a smart lighting strategy. Let’s review some lighting terms…
For the second installation of our greenhouse lighting series, we will be discussing the difference between the two most commonly used artificial lights in commercial greenhouse operations - HPS (high-pressure sodium) and LED (light-emitting diode). Read Part 1 here. A Brief Introduction HPS bulbs create light by sending electricity back and forth through an “arc…
The benefit of growing in a greenhouse, rather than growing indoors, is the ability to utilize free energy from the sun. The sun’s energy is more powerful and effective than any artificial light available. The downside is it’s not consistent. Sunlight intensity will fluctuate depending on a multitude of factors, so commercial greenhouse growers depend…
Major water quality considerations and ways to treat your water for optimal greenhouse production. When it comes to irrigation, cannabis cultivators get their water from a variety of sources. Whether it’s well, surface, or municipal water, it’s important to have a water treatment system in place to ensure optimal plant growth. If you’re reading…
Strong odors from cannabis farms can annoy and result in complaints from nearby residents. Many growers struggling with this issue control the smell by spending lots of money on odor mitigation systems such as masking agents or filters. While this is one way to keep happy neighbors, we believe a better solution starts with the…
At Ceres we are challenging the idea that “high tech” means “expensive” when it comes to greenhouse design. Between our patented passive solar structural design and our Ground to Air Heat Transfer (GAHT™) System, innovation is at our core and we aim to provide growers with the most energy-efficient growing solutions. We help our growers…
