Is It Legal to Grow Cannabis at Home in Missouri? (2026 Rules)

Jurisdiction: Missouri  |  Last verified: September 4, 2026  |  Program: Consumer and medical personal cultivation

Quick answer: Yes, but registration is required. A Missouri adult age 21 or older may apply for a consumer personal cultivation identification card. After approval, the consumer may grow up to six flowering plants, six nonflowering plants at least 14 inches tall and six nonflowering plants under 14 inches tall in one enclosed, locked facility at a private residence.

Missouri consumer cultivation rules in plain language

• Minimum age: 21 for a consumer personal cultivation card.
• Flowering limit: six plants.
• Larger nonflowering limit: six plants that are 14 inches tall or more.
• Smaller nonflowering limit: six plants under 14 inches tall.
• Location: one enclosed, locked facility at a private residence.
• Labeling: flowering plants must be labeled with the consumer’s name.
• License term: the consumer cultivation card is valid for 12 months and must be renewed.
• No sales: a personal cultivator may not sell the plants or cannabis produced from them.

What happens when two licensed consumers share a residence?

Two people with valid consumer cultivation cards may share a cultivation space at one private residence if both identify the arrangement in their approved applications. The residence cap is 12 flowering plants, 12 nonflowering plants at least 14 inches tall and 12 nonflowering plants under 14 inches tall, regardless of how many consumers live there.

Medical patient and caregiver cultivation

Missouri also issues cultivation authorization for qualified patients and primary caregivers. A patient must have an active patient identification card before obtaining patient cultivation authorization. Only one person in a patient-caregiver relationship may cultivate for that patient, and the ordinary per-patient limit is the same six flowering, six larger nonflowering and six smaller nonflowering plants.

Patient and caregiver rules include additional labeling, shared-space and possession requirements. Use the medical section of the official state cultivation page instead of applying the consumer rules to a patient grow.

Before you start

1. Choose the correct application. Consumer, patient and caregiver cultivation authorizations are not interchangeable.
2. Wait for approval. Save the approved cultivation card before bringing plants into the grow area.
3. Prepare the enclosure. It must be stationary, fully enclosed, locked and restricted to authorized cultivators.
4. Report shared cultivation. Both approved consumers must identify a shared space in their applications.
5. Track plant stages. Missouri uses separate limits for flowering, nonflowering at least 14 inches and nonflowering under 14 inches.
6. Keep it noncommercial. Do not advertise or sell homegrown cannabis.
