What is hemp
Hemp, also known as grass, is an annual herbaceous plant belonging to the Cannabaceae family. This plant comes from the Cannabis sativa species, which includes many varieties and strains.
Unlike marijuana, which is grown for its high THC content, industrial hemp is grown primarily for fiber and seeds, and has a very low THC content. Importantly, hemp and marijuana are difficult to distinguish in the field, although marijuana has a significantly higher THC content. In addition, hemp is also used in the manufacture of biocomposites, highlighting its versatility.
The hemp plant is known for:
- Its rapid growth
- Its resistance to insects and fungi
- It can reach a height of 2 to 5 meters
- It facilitates its annual harvest, since it has few branches
- It has a long history of use dating back to ancient times
- Its name comes from the Latin cannăbum, which in turn derives from the Greek κάννναβις.
The European Commission defines hemp as a species of the Cannabaceae family, related to cannăbis, with low THC, cultivated for industrial uses.
Hemp cultivation
Hemp cultivation is a sustainable practice that requires few pesticides and no herbicides, making it an attractive option for environmentally concerned farmers. Hemp is ideal for crop rotation because of its benefits to the soil.
Hemp’s deep roots suppress weeds and aerate the soil, improving its long-term quality. However, it is important to select suitable soils for its cultivation, avoiding those with high humidity or a lot of clay, and preferring well-drained soils with a pH between 6.0 and 7.0.
To maximize yields, it is advisable to plant hemp between May and June, avoiding soil compaction problems. Short-season varieties can mature before frost if planted until mid-June.
The optimum time to harvest hemp is when plants are between early flowering and seed production.
Hemp Varieties
There are several varieties of hemp, each cultivated for specific purposes. The main ones are industrial hemp and medicinal hemp. Industrial hemp is generally used in the production of textile fibers, paper and building materials, due to its low THC content. On the other hand, medicinal hemp is grown for its high CBD content and is used in therapeutic products. In addition, industrial hemp is also used in the production of biofuels, highlighting its versatility.
Hemp growers should carefully select the variety that best suits their needs and growing conditions. Industrial hemp varieties are designed to maximize fiber and seed production, while medicinal varieties are selected for their specific cannabinoid profile to treat various health conditions.
EU Regulations
In the European Union, hemp cultivation is subject to regulations that ensure its proper and safe use. Growers must use certified seeds with low THC content, and seed sellers must submit the necessary documentation for legal protection. These regulations also promote crop rotation to improve agricultural sustainability.
In Spain, Royal Decree 1729/1999 specifies the varieties of hemp authorized in the country.
In addition, to produce hemp seeds, it is a requirement to be registered as Seed and Nursery Plant Products and to comply with the Technical Regulations for the Control and Certification of Textile Plant Seeds. These regulations ensure that hemp grown in the EU meets the quality and safety standards necessary for industrial and medicinal use.
Uses of hemp
Hemp is an extraordinarily versatile plant, used for centuries for a variety of human needs. From the manufacture of ropes and candles in ancient times to its use in modern industry, hemp has proven to be an invaluable resource. It is also used in the manufacture of biocomposites and biofuels, highlighting its versatility.
Its low THC content makes it suitable for multiple applications, including the production of building materials, food and textiles.
Currently, hemp’s applications span diverse industries, such as textiles, automotive and construction.
Hemp-derived products include automotive components, building materials such as hemp concrete, and food and cosmetic products.
In addition, hemp is used as a substitute for plastic due to its light weight and durability.
Textile industry
Hemp fiber is recognized for being the longest, softest and strongest of the plant-based textile fibers. This characteristic makes it an ideal choice for the manufacture of clothing, bags and mats, among other textile products.
Hemp fabric is absorbent, durable, resistant and cool, which makes it highly demanded in the textile industry.
Interest in hemp fibers is on the rise due to its sustainability and lower environmental impact compared to other textile fibers such as cotton. Consumers and companies are increasingly interested in products that are not only high quality, but also environmentally friendly.
Food and feed – cannabis sativa seeds
Hemp seeds are an exceptional nutritional source, rich in protein, fiber, vitamins, omega-3 and minerals. Safe hemp-derived foods come exclusively from the kernels, such as oil, protein and flour. Hulled hemp seeds are highly nutritious and suitable for human consumption, while whole seeds are intended for animal feed.
CBD Alchemy, for example, offers a range of hemp-based foods selected for their quality and nutritional richness. In its online store, you can find everything from protein-rich breakfasts to Cannaline chocolates and a variety of hemp teas and infusions for relaxation.
Construction
In the construction industry, hemp is used in the manufacture of innovative materials such as hemp concrete, hemp wool and fiberboard insulation. These materials are not only sustainable, but also improve the energy efficiency of buildings. Hemp concrete, for example, continues to store carbon for the life of the building, contributing to the reduction of the carbon footprint. In addition, hemp is also used in the manufacture of biocomposites for construction, highlighting its versatility.
Hemp chipboard has twice the strength of wood and holds nails better, making it a robust and durable building material. These benefits have led to an increase in demand for hemp-based building products worldwide.
Properties of hemp
Hemp possesses unique properties that make it extremely versatile and useful in a variety of applications. Hemp fiber is more insulating, cooler, absorbent and durable compared to cotton. These characteristics make it ideal for the manufacture of clothing, industrial textiles and construction materials. In addition, hemp is also used in the manufacture of biocomposites, highlighting its versatility.
In addition, hemp is known for its strength and durability, making it an excellent choice for products that require high resistance to wear and tear. Its absorbency also makes it useful in the production of paper and cleaning products. These properties have been exploited for centuries and continue to be valued today.
Environmental benefits of hemp
Hemp is a plant that offers numerous environmental benefits, contributing significantly to the fight against climate change. It can absorb more carbon dioxide per hectare than other crops and many trees. In fact, hemp has a negative carbon balance, as it absorbs more carbon than it emits. In addition, hemp is ideal for crop rotation because of its benefits to the soil.
In addition to its ability to absorb CO2, growing hemp has other benefits:
- It helps revitalize the soil by absorbing heavy metals and facilitating its oxygenation.
