Bridging Yield Gaps in Cannabis Cultivation

In agriculture, a yield gap refers to the difference between a crop’s maximum yield potential and the yield the farmer actually achieves.[1] For cannabis, the yield gap is the difference between the highest possible flower yields and those currently achieved by commercial growers under optimal conditions. Data from 2018 collected from commercial cannabis growers in Canada found projected yields ranged from as low as 3.36 grams of dry flower per square meter to as high as 3,590 grams.[2] While there is …

Understanding Phytohormones

Plant hormones, called phytohormones, are chemical compounds that circulate through the plant, signaling and regulating its life cycle from seedling to maturity. In animals, hormones are “chemical messengers” produced by the endocrine glands. While plants do not have hormone-producing glands, phytohormones influence similar physiological processes as mammalian hormones, including growth, reproduction and even senescence.[1] In this blog post, we’ll discuss the importance of phytohormones, the specific types of phytohormones and the benefits of their exogenous application from natural sources. Why phytohormones matter Phytohormones are …

Secondary Metabolites of Cannabis

Secondary metabolites are chemical compounds that plants produce to fight against threats, adapt to environmental pressures and facilitate ecological relationships. In cannabis, these compounds go beyond basic growth and survival functions. They’re responsible for the plant’s recreational and medicinal benefits, as well as the distinct flavors and aromas that differentiate strains. The secondary metabolites of cannabis are unique in that they can be tailored to address specific medicinal or recreational needs, influencing the plant’s market value. In this blog post, we’ll explain …

Monitoring Runoff in Recirculating Hydroponic Systems

When cultivating cannabis hydroponically, growers can choose between drain-to-waste and recirculating systems. In drain-to-waste systems, the nutrient solution is discarded after use; in recirculating systems, the nutrient solution is reused. When using a recirculating system, it is important to collect and test the runoff—the excess nutrient solution that passes through the root zone—because it gives an idea of whether it is suitable for reuse or adjustments need to be made. Neglecting to monitor runoff can lead to salt buildup, resulting in …
