Hemp is a tall, gracious annual plant that can reach heights over twelve feet. Although hemp (cannabis sativa) and marijuana (cannabis sativa var. indica) come from a similar species of plant, they are very different and confusion has been caused by deliberate misinformation with far reaching effects on socioeconomics as well as on environmental matters.
Industrial hemp grows differently than THC-containing cannabis. Hemp is typically grown up, not out, because the focus is not on producing buds but on producing length of stalk. In this way, hemp is a very similar crop to bamboo. The stalk contains the fiber and hard, woody core material that can be used for a variety of purposes, even carpentry.
The two also differ in the areas that they can be effectively grown. THC-producing Marijuana must be grown in generally warm and humid environments in order to produce the desired quantity and quality of THC-containing buds. However, since industrial hemp does not contain these buds, and the hardy parts of the plant are the more desired, it can be grown in a wider range of areas. Generally, industrial hemp grows best on fields that provide high yields for corn crops, which includes most of the Southwest, Southeast, and Northeast United States. Furthermore, since industrial hemp can use male plants as well as female plants (since the object is not THC production), higher crop yields can result.
Hemp has the strongest natural fibres, which can be used not just to produce rough cloth, such as sails or canvass, but also durable work clothes, like the original jeans. When the plants are grown closer together the fibre becomes shorter and finer, which allows for finer textiles. Today, there are some fashion designers that are experimenting with a wide range of textiles made from hemp for their stylish, trendy hemp lines, shirts, suits, bags, jeans and more. Hemp fibres can be blended with water and limestone to create an extremely tough, light-weight, natural cement that has not only excellent insulating properties, but also shows more flexibility than conventional concrete, which makes it particularly useful as a building material in earthquake prone areas.
