Hemp stats on legal definition and classification

Hemp is legally classified based on its THC content, distinguishing it from marijuana. Regulations for this vary by country. This is the legal requirement hemp has to fulfill. 

1. Industrial hemp is legally defined as Cannabis sativa with THC levels at or below 0.3% of the dry weight of the flowering portion of the plant. THC is the primary psychoactive chemical found in marijuana. With levels as low as 0.3%, there will be no intoxicating effects. 
2. In European countries, the THC levels may not be above 0.2% for it to classify as hemp.

Hemp stats on its growth and cultivation

Hemp is a fast-growing crop that thrives in various climates. Different varieties are suited for temperate and tropical regions. Here are some amazing hemp statistics about the plant. 

Growth Characteristics

3. Hemp can grow to a height of 1.5m to 4m. That is about the length of a standard hatchback car. 

4. Hemp reaches up to 12 feet in height within three to four months. It is a very fast-growing crop and thus is often used as a rotation crop or grown twice in a year. 

5. Hemp can yield three to eight tons of dry stalk per acre, depending on climate and variety.

6. Hemp breeders aim to produce hemp with the size of flax or a little longer, which is around 30 cm.

7. Hemp covers approximately 10,000 ha/year in France. 

Yield & Biomass Production

8. 1 ha of hemp can produce nearly 12 t of dry matter (DM)/year with a humidity level of 15%. This dry matter is what gets processed into hemp’s other uses. 12 tons of dry hemp matter can produce about 4,000 – 5,000 hempcrete bricks. This is enough to insulate a small house. 

This amount of dry matter can also be used to produce 24,000 sheets of paper or up to 10,000 meters of hemp fabric. 

9. Exported straw from 1 ha of hemp is about 8 t (or 6.8 t of DM).

10. Hemp stalks produce 4–12 t of dried straw per hectare with 15% humidity.

11. One tonne of hemp straw yields:

        a. 0.55–0.65 t of hurds

        b. 0.2–0.3 t of fiber

        c. 0.15 t of powder

Soil Benefits & Nutrient Return

12. Hemp can return 60% of nutrients back to the soil when dried and ploughed back into the soil.

13. Hemp can return as much as two-thirds of the organic matter to the soil if it is field-retted.

Hemp stats on its carbon sequestration capabilities & environmental impact

Hemp is famously known as a carbon skin because it absorbs CO₂ rapidly. Carbon sinks are anything that absorbs more carbon dioxide than they produce. Because hemp grows faster than trees, it is hailed as an efficient carbon absorber. Here are some stats on hemp’s ability to absorb carbon.

Carbon Absorption

14. Hemp’s carbon uptake can be up to 22 tonnes per hectare, which is higher than agroforestry. 22 tonnes of CO₂ is equivalent to the emissions of 2.9 homes in one year. It can also be equated to about average gasoline-powered cars driven for a year.

15. One hectare of industrial hemp can absorb 15 tonnes of CO₂ per hectare.

16. Hemp contains approximately 45% of the atmospheric carbon taken up during photosynthesis.

17. Hemp’s rapid growth makes it one of the fastest CO₂-to-biomass conversion tools. 

18. As it is possible to grow two hemp crops per year, we can offset up to 30 tons of CO₂ per hectare in a year. 

Hemp stats on its fiber and textile applications

Hemp is a high-yield fiber crop, with fiber-to-Hurd ratios varying by variety. Temperate hemp produces more fiber than tropical strains, making it ideal for textiles. Here are some hemp statistics on the strength and durability of hemp fibers. 

19. Hemp fiber bundles can be up to 15 feet long.

20. Bast fibers of hemp range from 1.2m to 2.1m in length.

21. Bast fiber constitutes 0.2-0.3 t of fiber per 1 t of straw.

22. Hemp fiber and cellulose have lengths varying between 5 and 60 mm.

23. Hemp fiber is used to create blend yarns with 20-30% cottonized hemp content.

24. Hemp textiles provide protection against UV radiation. Hemp fabric can reportedly block 99.9% of UVA and UVB rays earning it a UPF rating of 50+. This makes it an ideal choice for outdoor wear.
