What is Hemp and How Does it Differ from the Marijuana Plant
Hemp and marijuana are both plants within the Cannabis genus, but they are distinct in their genetic makeup, physical appearance, and chemical composition.
Hemp is a strain of the Cannabis plant that is grown for its industrial uses, such as fiber, oil, and seeds. Hemp has a lower concentration of THC (tetrahydrocannabinol), the psychoactive compound responsible for the “high” associated with marijuana. In the United States, hemp is legally defined as any Cannabis plant that contains less than 0.3% THC by dry weight. This means that hemp does not have the same psychoactive effects as marijuana, and it is commonly used for industrial and commercial purposes.
Marijuana, on the other hand, is a strain of the Cannabis plant that is grown for its high THC content and psychoactive effects. Marijuana plants typically have a higher THC concentration than hemp, with some strains containing upwards of 30% THC. Due to its psychoactive effects, marijuana is used primarily for recreational or medicinal purposes.
In terms of physical appearance, hemp plants are typically taller and thinner than marijuana plants, with thinner leaves and branches. Marijuana plants are shorter and bushier, with broader leaves and dense buds.
Exploring Different Varieties of Hemp Plants
There are three different species of hemp cannabis plants: Cannabis sativa, Cannabis indica, and Cannabis ruderalis. These species have different physical and chemical characteristics, and are often used for different purposes.
Cannabis sativa is a tall, thin plant with narrow leaves and a long flowering period. It is typically grown for its fiber, which can be used to make a wide range of products, including clothing, paper, and building materials. Sativa strains of hemp can also be used for oil extraction and CBD production, as they often have higher concentrations of these compounds.
Typically, hemp farmers will choose to grow only female hemp crops when harvesting Cannabis sativa plants for CBD production. This is because female hemp plants produce flowers with a high concentration of cannabinoids, like CBD, when compared to male hemp flowers. Additionally, in order for hemp derived products to comply with federal law in the United States they must contain less than 0.3% delta-9 THC by dry weight. Since female plants typically contain higher CBD content and lower THC content than male plants, they are ideal for hemp farmers looking to ensure maximum CBD production in their crop.
Cannabis indica is a shorter, bushier plant with wider leaves and a shorter flowering period than Cannabis sativa. It is often grown for its psychoactive properties, as it has higher concentrations of THC than sativa strains. However, indica strains of hemp can also be used for CBD and CBG production, as well as for fiber and seed production.
Cannabis ruderalis is a smaller, less common species of hemp that is often used for breeding purposes. It has a shorter growing period than sativa and indica strains, and is often used to create auto-flowering hemp varieties that do not require careful control of light cycles. Ruderalis strains of hemp typically have lower concentrations of THC and other cannabinoids than sativa and indica strains, but they may still be used for CBD and CBG production.
Exploring the Potential Benefits of Various Hemp Varieties

Using Hemp for a Variety of Applications: Clothing, Rope, Paper & More
Hemp plants have a long history of use in various industries due to their versatile nature and numerous beneficial properties. Here are some examples of different varieties of hemp:
Textiles
Hemp has been used for textiles for thousands of years, thanks to its strong, durable, and versatile fibers. Hemp plants are typically harvested when the fibers in the stalks are at their strongest. The stalks are cut and then left to dry in the field. The dried hemp stalks are then subjected to a process called retting, which involves soaking the stalks in water to break down the natural pectin that binds the fibers together. This can be done in a variety of ways, such as in a pond or stream, or using specialized machinery.
Once the stalks have been retted, they are put through a machine called a breaker, which separates the outer bark from the inner fibers. This produces long, strong fibers that can be used for textiles. The fibers are then subjected to a process called scutching, which involves beating the fibers to remove any remaining bark or impurities. The fibers are then combed and aligned using a process called hackling, which produces long, fine strands of hemp fiber that are ready for spinning into yarn.
The hemp fibers are spun into yarn using spinning machines, which can produce a range of different yarn thicknesses and qualities depending on the intended use. The hemp yarn is then woven or knitted into fabrics using specialized looms or knitting machines. Hemp fabrics can be used for a wide range of applications, such as clothing, upholstery, and home textiles.
Hemp fiber is incredibly strong and durable, making it an ideal material for producing textiles such as clothing, rope, and paper. Hemp textiles are also environmentally friendly, as they require fewer pesticides and fertilizers than other crops, making them a popular choice for eco-conscious consumers.
