Back in 2000, the State of Hawaii legalized marijuana for medical use but it took almost 20 years for cannabis to be decriminalized throughout the state. In 2020, recreational use of marijuana was decriminalized (under three grams) and the change is thought to be a precursor for full legalization in coming years, with the Hawaii Senate approving bills for cannabis legalization earlier this year.

Hawaii is unique when it comes to growing seasons – even outdoor grows can take place all year round – the longest day in Hawaii has only 2.5 more hours of sunlight than it’s shortest. Outdoor growers on the islands can enjoy two growing seasons every year – the long season (spring to fall) and the short season (harvest in winter, spring, and early summer).

Whilst the extra grow season makes for a happy grower – outdoor growing in Hawaii isn’t without problems, for example mold and mildew, low nitrogen and calcium soil and invasive species, so some experience is recommended.
