You’re looking for some deep cuts into the world of hemp, huh? Here are 10 rarely known facts that might surprise you:
Hemp Can Hyperaccumulate Toxins: Like some other plants, hemp has the ability to absorb heavy metals and other toxins from the soil. This process, called phytoremediation, can be useful for cleaning up contaminated land, but it also means that hemp grown in such environments wouldn’t be suitable for consumption or textiles without proper processing and testing.
Hemp Was Once Used in Photography: In the early days of photography, hemp oil was sometimes used in the production of photographic emulsions.
Hemp Seeds Were a Common Birdseed: Before the widespread cultivation of other grains for birdseed, hemp seeds were a popular and nutritious option for feeding birds. Their small size and high oil content made them appealing.
Hemp Has a Long History in Bookbinding: Due to its strength and durability, hemp fiber has been used in papermaking and bookbinding for centuries, contributing to the longevity of historical texts.
Hemp Can Be Used to Make Musical Instruments: While not mainstream, some luthiers and instrument makers have experimented with using hemp composites in the construction of guitars and other musical instruments, citing unique tonal qualities.
Hemp Oil Was Used in Paints and Varnishes: Before the dominance of petroleum-based products, hemp seed oil was a common ingredient in paints, varnishes, and even lamp oil due to its drying properties.
Hemp’s Role in Early Plastics: While not the plastics we know today, cellulose derived from hemp was used in early forms of plastics and cellophane.
Hemp Can Produce More Biomass Than Forests: Per unit of land, hemp can produce more biomass at a faster rate than most forests, making it a potentially valuable source for biofuels and bioplastics.
Hemp’s Complex Genetics: The Cannabis sativa species has a remarkably complex genome, with significant variation between different varieties (including hemp and marijuana) that scientists are still fully understanding. This genetic diversity contributes to the plant’s wide range of applications.
Hemp Played a Role in Aviation History: Early airplane wings were sometimes covered with fabric made from strong hemp fibers due to their lightweight and durable nature.
