Home Grow Laws in Hawaii
Only registered medical cannabis patients may grow at home.
Plant Limits
Overview
Hawaii allows home cultivation of cannabis exclusively for registered medical cannabis patients. Under the state's medical cannabis program, qualifying patients may grow up to 10 cannabis plants at any given time, with no specific distinction between mature and immature plants in the statewide limit. Patients must register with the Hawaii Department of Health and designate a growing location. Hawaii's tropical climate provides an excellent year-round growing environment with abundant sunlight.
Recreational cannabis remains illegal in Hawaii, and home cultivation for non-medical purposes is prohibited. Despite several legislative attempts to legalize recreational use, none have passed as of now. Medical patients must adhere to strict rules about their grow site, including keeping plants in a locked and enclosed area. Caregivers may grow on behalf of patients, but must also be registered with the state. The islands' unique growing conditions, including high humidity and strong trade winds, create both advantages and challenges for cannabis cultivators.
