Drug-type cannabis species (containing higher levels of psychoactive THC). Hemp, or industrial hemp, is a botanical class of Cannabis sativa cultivars grown specifically for industrial or medicinal use. It can be used to manufacture a wide range of products. Along with bamboo, hemp is one of the fastest growing plants on Earth.
It was also one of the first plants to be converted into usable fiber 50,000 years ago. It can be refined into a variety of commercial items, such as paper, ropes, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food and animal feed. Hemp (Cannabis sativa), also called industrial hemp, a plant in the Cannabaceae family that is cultivated for its bast fiber or its edible seeds. Hemp is sometimes confused with cannabis plants that serve as sources of the drug marijuana and the hashish prepared for the drug.
Although all three products (hemp, marijuana and hashish) contain tetrahydrocannabinol (THC), a compound that produces psychoactive effects on humans, the cannabis strain cultivated for hemp contains only small amounts of THC compared to that grown for the production of marijuana or hashish. The main difference between hemp plants and other cannabis plants is due to their cultivation, use and, most importantly, the levels of the delta-9 compound tetrahydrocannabinol (THC). Some specially processed hemp has an off-white color and an attractive sheen and are used to make linen-like fabrics for clothing. Hemp may be one of the oldest known plants that humans cultivated for medicinal and nutritional purposes.
Cannabis is a complex plant, with important compounds such as delta-9-tetrahydrocannabinol and cannabidiol, which have opposite effects. Hemp fiber is used to make bioplastics that are recyclable and biodegradable, depending on the formulation. This was traditionally followed by frizz, either by water (stained hemp floats in water) or by dew (hemp stays in the soil and is affected by the humidity of the dew and by the action of mold and bacteria). Hemp is more commonly used as concrete in building construction because of its lightness (approximately seven times lighter than common concrete).
Although chemotype I cannabis and hemp (types II, III, IV, V) are Cannabis sativa and contain the psychoactive component tetrahydrocannabinol (THC), they represent different groups of cultivars, usually with unique phytochemical compositions and uses. The most common use of hemp lime in construction is to mold the hemp-lime mixture while moistening it around a wooden frame with temporary formwork and tamping the mixture to form a firm mass. In addition to the CO2 absorbed during its growth period, hemp is repeated during the creation of concrete. Hemp differs from other forms of cannabis in several ways, including its cultivation, use and THC levels.
Hemp fiber is known to have great strength and durability, and is known to be a good protector against vermin. Hemp plants can be vulnerable to several pathogens, such as bacteria, fungi, nematodes, viruses, and other diverse pathogens. Hemp is grown in temperate areas as an annual plant grown from seed and can reach a height of up to 5 meters (16 feet).
