Home cannabis cultivation in Honolulu is governed exclusively by Hawaii state law HRS 329-122, allowing 329-card patients to grow up to ten tagged plants at a single registered residence; recreational home grows remain illegal citywide.
Cannabis home cultivation in Honolulu is controlled entirely by state law, with no separate ROH provisions. HRS 329-122 allows qualifying patients with a Hawaii 329 medical card, and specified caregivers (since January 1, 2024 limited to minors and incapacitated adults), to cultivate up to ten cannabis plants at a single registered grow site. That site must be the patient's residence, caregiver's residence, or a site under their control. Plants must be tagged with the 329 card number and expiration date. Transport between islands is prohibited, and recreational cultivation remains illegal throughout Honolulu and the rest of Hawaii.
Exceeding ten plants, growing without a 329 card, inter-island transport, or misuse of tagged plants can result in loss of medical privileges and state criminal drug charges under HRS Chapter 329.
