Cannabis Pests and Pathogens
Pests and pathogens threaten cannabis crops. Pests—larger organisms[1] like insects and mites—physically damage plants, whereas pathogens are microorganisms that infect and cause diseases within plants. A useful rule of thumb might be that while pests can typically be removed physically, pathogens cannot.Both pests and pathogens pose distinct threats to plant health, reducing cannabis yield and quality. This blog post explores some of the most common pests and pathogens that cannabis growers may encounter, the specific plant sites they target, and …

Types of Growing Media
Choosing the right growing medium for indoor cannabis cultivation is no simple matter. Growers need a substrate that has high porosity and proper consistency, retains a moderate amount of water between irrigations, drains and dries rapidly, is free from pests and pathogens, and strikes a good balance between physical and chemical properties. Growing media may consist of organic components derived from natural matter—such as peat, coir, wood, bark, compost or biochar—or inorganic materials like perlite, expanded clay, pumice, rockwool or vermiculate. And …

Why the Growing Medium Matters
In soilless cultivation like hydroponics or container gardening, growers typically use a growing medium, also called the substrate, made from coconut fiber, rockwool, perlite or another porous material in which their plants can take root.[1] Providing an “artificial” environment for the roots offers several benefits over soil: The growing medium is often infertile, so growers have complete control over nutrient levels. The risk of soilborne pests and pathogens is lower. And it can improve water and resource efficiency. However, not all growing …
