Hawaii’s Huge Industrial Hemp Potential

A study by University of Hawai‘i College of Tropical Agriculture and Human Resources suggests more than 70 tons of industrial hemp could be produced per acre each year in the state. 

Evidence from a feasibility study indicates 3 hemp crops could be grown a year in Hawai’i. These crops would yield between between 27 – 38 tons dry weight of stalks per acre annually and between 31 and 35 tons dry weight of stems and leaves.

The stalks could be used to produce items such as hempcrete; a building material with good insulation qualities and just a fraction of the weight of concrete.

Dried stems and leaves can be used for animal forage. Apparently, the meat produced by livestock feeding on industrial hemp is more nutritious than corn fed beef.

The subtropical seed hemp cultivar trialed during the study would be able to produce 2 crops a year, with a yield of around 2.5 tons of seed per acre per year.  Hemp seed is used for human food and in the production of personal care products.

While the subtropical fiber hemp grew at a very rapid rate –  mean of 1.9 m in 15 weeks – it was a real water-miser; requiring only 10 mm of water per week.

Temperate zone hemp was also trialed, but only grew to a height of about 2 feet before flowering and then dying.

The University’s research project has certainly been successful, but the report lamented some of the hoops the team had to jump through to perform the feasibility study.

“It is unclear why industrial hemp is classified as a drug. It took 11 months between starting the process to import hemp seeds for growth trials until the seeds arrived,” said Maria Gallo, author of the report and Dean of the College of Tropical Agriculture and Human Resources.

The study concludes positively.

“There is significant potential for a successful hemp agricultural industry in Hawai‘i based on the preliminary findings of the 2015 Industrial Hemp Research Project,” states Dean Gallo.
