In hemp cultivation, “topping” refers to the process of selectively cutting off the upper portion of the plant during its vegetative (growth) phase. This practice holds a central and essential role in plant training, as it encourages horizontal growth and optimizes light utilization, resulting in increased yields. When a plant is topped, the two auxiliary buds located just below the cut site develop into full-fledged branches, often taking on a Y-shaped structure. These secondary branches can also be subjected to…

In the early stages of growth, hemp plants tend to exhibit a pattern of stacked leaves, both horizontally and vertically. This growth pattern is characterized by leaves arranged in pairs at regular intervals along the stem, and as the plant grows, these pairs of leaves may be found at different vertical levels on the stem. This phenomenon is a typical part of the plant’s vegetative growth phase, where it is actively developing its leaves and stems. As the plant matures,…

Powdery mildew in hemp is a common fungal disease that can affect the health and yield of hemp plants. It’s caused by various species of fungi, with Podosphaera xanthii and Golovinomyces cichoracearum being common culprits. Powdery mildew typically appears as white or grayish, powdery spots or patches on the leaves, stems, and even flowers of hemp plants. Infected leaves may curl, become distorted, or die prematurely. As the disease progresses, the powdery spots can merge, covering larger areas of the…

In hemp plants (Cannabis sativa), the highest concentrations of THC (Tetrahydrocannabinol) and CBD (Cannabidiol) are typically found in the female flowers, especially in the resinous trichomes that cover the flowers and leaves. These trichomes produce the cannabinoids, including THC and CBD, as well as other compounds such as terpenes, which contribute to the plant’s aroma and flavor. Hemp plants are typically grown for their industrial uses, including the production of fiber, seeds, and oil. In many hemp cultivars, the THC…

Beet curly top virus (BCTV) is a destructive plant virus that primarily affects plants such as sugar beets, tomatoes. It is primarily transmitted by the beet leafhopper (Circulifer tenellus), which feeds on plant sap and can carry the virus from infected plants to healthy ones. Symptoms of Beet Curly Top Virus on leaves and plants typically include leaf curling. Leaves of infected plants often exhibit severe curling, puckering, and distortion. This is one of the most characteristic symptoms and gives…

Hemp (or industrial hemp) is Cannabis sativa which is a member of the Cannabaceae family. Actually, Cannabis sativa and Cannabis indica are two of the primary subspecies or varieties of the Cannabis plant, each with its own set of characteristics. It’s important to note that while hemp is a variety of Cannabis sativa, not all cannabis is hemp. The name “cannabis” refers to a genus of flowering plants in the family Cannabaceae, which includes both hemp and marijuana. While both…
