Preparing Stock Solution
When feeding cannabis crops in hydroponic systems, growers must first prepare a stock tank solution—either using a complete fertilizer line from a reputable manufacturer or by mixing and matching fertilizers themselves. With a complete fertilizer line, creating a stock solution is straightforward: simply follow the manufacturer’s instructions. But for those who prefer to mix their own fertilizers, the process is more complex. Growers must understand the nutrient concentrations in each fertilizer, how much they want to feed and the dilution …

Flushing in Cannabis Cultivation
Flushing is the practice of halting fertilization before harvest and irrigating plants with plain water instead. The goal is to remove excess salts from the growing medium and the plant.[1] Growers typically flush for two reasons: First, nutrient deprivation is believed to trigger secondary metabolite production as a stress response, indirectly increasing the quality (i.e., color, fragrance, flavor and potency) of the end product. Second, reducing the plant’s nutrient content may degrade chlorophyll, which some believe contributes to the harshness or …

Canopy Lighting in Cannabis Cultivation
One of the biggest challenges for indoor cannabis growers is replicating the sun’s ability to penetrate the plant canopy, particularly the lower portions. Outdoors, photons[1] from natural sunlight strike leaf surfaces at multiple angles throughout the day, ensuring light distribution throughout the plant. By contrast, traditional overhead lighting in indoor cultivation struggles to reach the lower canopy, limiting photosynthesis and yields. To remedy this problem, canopy lighting has emerged as an effective method for ensuring all parts of the plant receive adequate …

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 …
