Tagging Medical Cannabis Plants
Learn the requirements for tagging medical cannabis plants in Hawaiʻi, including what information to include on tags and why proper tagging is crucial for 329 Cardholders.
Growing & Possession Rules Hawaiʻi Medical Cannabis : Growing & Possession Guidelines At Greener Healing Ways, our goal is to help patients stay informed and compliant with Hawaiʻi’s medical cannabis program. Below is an overview of the current rules for those who grow or possess medical cannabis under a valid 329 Card. Adequate Supply Limits A registered patient and their caregiver together may have up to 10 cannabis plants (mature or immature) and 4 ounces of usable cannabis at any time. The 4-ounce limit includes all usable forms of cannabis, including flower, oils, and manufactured products. “Usable cannabis” refers to dried leaves and flowers ready for use. It does not include seeds, stalks, or roots. Cultivation & Grow Site Patients who choose to grow must declare one grow site on their Department of Health application. The address on your 329 Card must match the physical grow location. Cultivation must take place in a secure, enclosed area that is not visible to the public. Each cannabis plant must have a legible identification tag showing the 329 registration number and card expiration date. Caregiver Cultivation Updates As of January 1, 2025, caregiver cultivation is limited in most cases. Patients who live on islands without licensed dispensaries or those who require caregiver assistance due to age or disability may still qualify for caregiver cultivation. Executive guidance issued in late 2024 allows caregivers who cultivate within lawful limits to continue doing so without penalty while the state finalizes long-term regulations. Purchasing Limits Dispensaries may sell up to 4 ounces within any 15-day period and 8 ounces within any 30-day period to a registered patient. Tagging Medical Cannabis Plants in Hawaiʻi The Importance of Proper Tagging At Greener Healing Ways , we want our patients to stay fully informed and compliant with Hawaiʻi’s medical cannabis laws. While our clinic does not participate in cultivation or tagging , we feel it’s important to understand the rules that apply to patients who choose to grow their own medicine. Proper tagging protects you by clearly identifying your plants as part of the Hawaiʻi Medical Cannabis Registry Program . Tags provide proof that your plants are legal and registered, help prevent misunderstandings with law enforcement, and demonstrate that you’re following Department of Health (DOH) regulations. What the State Requires According to the Hawaiʻi Department of Health , all registered patients and caregivers who grow medical cannabis must follow these guidelines: Every cannabis plant must have a legible identification tag attached directly to the plant. Each tag must clearly display the 329 registration number and the expiration date of your medical cannabis card. Tags must remain visible and easy to read at all times. Replace any tag that becomes damaged, faded, or illegible. The grow site address listed on your application must match the physical location of your plants. These requirements come directly from Hawaiʻi Administrative Rules HAR §11-160-31 . Why It Matters Tagging your plants helps ensure that you remain compliant with state law and protects your right to grow. It clearly shows that your cannabis is grown for personal medical use under a valid 329 registration. It helps prevent confusion or potential penalties if your grow site is ever inspected. It reflects your commitment to cultivating responsibly and within legal limits. Key Reminders You and your caregiver (if applicable) may grow up to 10 cannabis plants total, mature or immature. The total usable cannabis (flower, oils, etc.) must not exceed 4 ounces at any time. You may only grow at the address registered with the DOH . Inter-island transport of cannabis is not permitted.
