In August of 2018, Hawaii joined the ranks of the hemp industry after they granted three farmers licenses to grow hemp. This was the first of many steps for Hawaii to join the hemp industry.
Plant Hardiness Zone(s)
Owing to its diverse terrain, Hawaii has 11 hardiness zones. Depending on where one It’s not at all unusual for a person’s property to encompass more than one hardiness zone.
Temperatures and humidity are less extreme than other tropical regions due to the trade winds that come in from the east. While summer highs are typically around 88 degrees Fahrenheit they dip down to around 83 degrees Fahrenheit at night. Lower elevations rarely dip below 65 degrees Fahrenheit at night. While snow isn’t typically seen in the tropics, at the 13,800-foot level it’s not unheard of in some of the colder winter months.
Length of Growing Season
Due to its unique geographical location and warm climate, Hawaii has a yearlong, 365 days, growing season. This is divided into two distinct seasons, one covering the warmer summer months – May through to October – and the other covering the cooler winter months – November to April. Since hemp takes an average of 120 days to grow from seedling to mature plants ready for harvest, local farmers can reap two harvests each year.
Average Annual Sunlight
Most parts of Hawaii receive an average of about 3000 hours of sunlight each year; this translates to over 9 hours of sunshine each day. During the months of April to September, each day receives more than 12 hours of sunshine. Farmers who intend to grow hemp during the months of November to March may need to use an artificial source of light, in an indoor growing environment, to meet the sunlight requirements of the plants during the vegetative stage.
Average Annual Precipitation
Thanks to a tropical climate, Hawaii has the second-highest annual rainfall rate on earth of about 460 inches annually. There are essentially two seasons in the State of Hawaii; the we season and the dry. The wet season encompasses October to April with the dry season encompassing May to October.
Interestingly, although Hawaii is comprised of islands, the highest point of the state is 13,796 feet and the lowest point is at the level of the Pacific Ocean. Hawaii enjoys an average of 271 sunny days annually and a very tropical climate.
Soil pH will vary greatly from one field to the next and, in the case of large fields planted on the steeper slopes of Hawaii’s mountains, soil types — and consequently soil pH — could vary across the same if the field.
Soil composition will vary greatly depending on the elevation and volcanic region in which the field lies. Pests include the typical fare of ants, various beetles, twig borers, mealy bugs, spider mites, and aphids.

Obtaining A Hemp Grower’s License In Hawaii
Under federal law, it is illegal to grow hemp anywhere in the United States without first obtaining a grower’s license from the appropriate regulatory body for the state in which the interested party intends to plant the crop.
