Missouri Residential Weed Growing

Missouri law requires that your cultivation space be enclosed and locked at all times. Whether you’re using a closet, spare room, greenhouse, or outdoor shed, it must have a lock that prevents unauthorized access. Only you (and your licensed caregiver, if applicable) can have access, and the space must be clearly designated for cultivation use only.

Every flowering plant must be tagged with your full name and the patient cultivation ID number. These labels help prove that your plants are legal if ever inspected. Keep your cultivation authorization posted inside the grow area too - this small step ensures full compliance and protects you in case of questions.

You’re allowed to grow 6 flowering plants, 6 non-flowering plants (over 14”), and 6 clones (under 14”) at one time. If you share a space with another licensed patient or caregiver, limits increase accordingly - but must always be tracked. Exceeding these numbers can lead to fines or revoked privileges, so it’s best to document and stick to your limits.

Your plants must never be visible from a public space, including streets, sidewalks, or neighboring properties. This applies even if you’re growing outdoors in a fenced yard or behind a greenhouse window. Use curtains, opaque barriers, or solid fencing to maintain privacy and avoid legal issues.

As a medical patient, your homegrown cannabis is for personal medical use only. Missouri strictly prohibits the sale, distribution, or gifting of homegrown weed, even to other medical patients. To stay compliant, keep all harvested product stored securely and only consume what you grow within your legal possession limits.

Both your medical marijuana card and cultivation license must remain valid. Missouri sends reminders before expiration, but it’s your responsibility to renew on time. Lapses can interrupt your legal protection and may require reapplication from scratch - set calendar alerts and renew at least 30 days in advance.
