Cannabis sativa, commonly known as hemp, is a botanical class of Cannabis sativa cultivars grown for industrial or medicinal use. It is one of the fastest growing plants on Earth and was one of the first plants to be converted into usable fiber 50,000 years ago. Hemp can be refined into a variety of commercial items, such as paper, ropes, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food and animal feed. It is also known as industrial hemp and has limited intoxicating potential compared to its subspecies Indica.Marijuana, hemp, and cannabis are all common names for plants in the genus Cannabis.
Hemp is used for cannabis plants that are grown so as not to use drugs. It can be used to manufacture a wide range of products and is seven times lighter than common concrete. Hemp was a cash crop commonly used to make ropes and webs in the past and is still used in building construction today. Different stitches are used to create hemp jewelry, with half knot and full knot stitches being the most common.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 1997, Ireland, parts of the Commonwealth and other countries began to legally cultivate industrial hemp again.
