Hemp is made of marijuana plants. The part of the plant used to make flax is a stem, while the leaves are most often used for marijuana. Hemp itself will not work to get anyone "height."
Hemp has an incredible amount of use that reaches many industries. These include clothing, paper, automotive, fuel, food products, and more. Hop over here to buy CBD infused hemp tea.
Hemp grows well in the open without pesticides or herbicides. Cotton, however, needs a lot of agricultural chemicals to thrive and uses half of the pesticides sprayed in the world. Hemp's deep rooting system actually removes toxins and aerates the soil which benefits future crops.
As opposed to cotton, hemp fibers are longer, stronger, more insulative, and more absorbent. Effectively this means hemp will keep a person cooler in the summer and warmer in the winter than cotton will.
Hemp clothing is less likely to fade than cotton and can be made into a variety of fabrics, including linen. Hemp fabrics are soft, sturdy, and block ultraviolet light well.
Hemp is also frequently used in the auto industry as a substitute for fiberglass. With hemp being biodegradable and cheaper, it's a step in the environmentally conscious direction.
Also, hemp has the potential to become a biodegradable plastic, which would be a substantial improvement over existing technology.
