Home Growing Is Legal — With a Card

Missouri allows adults 21 and older to cultivate cannabis at home for personal use. However, unlike most legal states, Missouri requires a state-issued cultivation card before you can grow. This is not optional — growing without a card is a violation that can result in fines or felony charges depending on the number of plants.

The cultivation card system was established by Amendment 3 and is administered by the Division of Cannabis Regulation (DCR). The card costs $56.27 and must be obtained before planting your first seed.

Qualifying patients, primary caregivers, and adults may apply to the department for a personal-use cultivation facility license to cultivate marijuana for personal use.

Missouri Constitution, Article XIV, Section 2

Plant Limits

Missouri's cultivation limits are among the more generous in the nation, distinguishing between three categories of plants:

The Cultivation Card

How to Get One

• Apply through the DCR's online portal
• Provide proof of Missouri residency and valid ID (21+)
• Pay the $56.27 fee
• Receive your cultivation card — you may begin growing once the card is issued

Key Card Rules

• The card is specific to your address — you cannot grow at a location other than your registered residence
• You must keep the card current and valid at all times while plants are growing
• If you move, you must update your address with the DCR

The Enclosed Locked Facility Requirement

All home-grown cannabis must be cultivated in an enclosed, locked facility. This is one of Missouri's most important cultivation rules:

• The grow space must be fully enclosed — a room, closet, garage, shed, or greenhouse with walls, a ceiling, and a door
• The space must have a functioning lock that prevents unauthorized access
• Plants must not be visible from a public place without the aid of binoculars or other optical devices
• The space must be secure from minors

A backyard garden with no enclosure does not qualify. A locked bedroom, a garage with a lock, or a locked greenhouse all meet the requirement.

Two Growers Per Residence

Amendment 3 allows up to 2 authorized cultivation cardholders per residence. This means a household with two adults who both hold cultivation cards can grow up to 36 plants total (18 each). However:

• Each grower must have their own cultivation card
• Plants should be reasonably attributable to each cardholder
• A third adult in the household cannot get a cultivation card for that same address

Personal Use Only

Home-grown cannabis is strictly for personal use. You may not:

• Sell any home-grown cannabis (this is illegal regardless of amount)
• Distribute to dispensaries or other licensed businesses
• Process for commercial purposes

You may gift home-grown cannabis to other adults 21+, following the same gifting rules that apply to purchased cannabis.

What You Can Make at Home

Missouri allows limited home processing of your own harvest for personal use:

• Edibles and infusions: You can make your own edibles, tinctures, and butter/oil using your home-grown cannabis
• Concentrates: The rules around home extraction are still developing. Solvent-based extraction (butane, propane) is generally considered dangerous and may violate local fire codes

Growing Without a Card: Penalties

Growing without a cultivation card carries serious consequences:

The $56.27 cultivation card is a small price compared to the penalties for growing without one. Get the card first.

Practical Tips for Home Growers

• Start with the card. Apply and wait for approval before purchasing seeds or clones.
• Invest in a proper lock. A padlock on a closet or room door satisfies the enclosed locked facility requirement.
• Control odor. While legal, strong odors can attract attention and create neighbor disputes. Carbon filters are an effective solution.
• Track your plant count. Know exactly how many flowering, vegetative, and clone plants you have at all times. Exceeding limits can be a felony.
• Keep your card accessible. If law enforcement ever asks, you should be able to produce your cultivation card promptly.
