🌿 Hawaiʻi Medical Cannabis: Growing & Possession Rules (329 Card)
A Greener Healing Ways guide for registered patients and caregivers
🌿⚖️ 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 (flower, oils, and manufactured products).
“Usable cannabis” means dried leaves and flowers ready for use; it does not include seeds, stalks, or roots.
🏡🔒 Cultivation & Grow Site
Declare one grow site on your DOH application; the address on your 329 Card must match the physical grow location.
Grow in a secure, enclosed area that is not visible to the public.
Each plant must have a legible 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 on islands without licensed dispensaries, or those needing assistance due to age or disability, may still qualify.
Executive guidance (late 2024) allows compliant caregiver grows to continue while long-term regulations are finalized.
🛒📏 Purchasing Limits
Dispensaries may sell up to 4 ounces in any 15-day period and 8 ounces in 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.
