Under Missouri Constitution Article XIV §2, registered patients and adults 21+ may cultivate up to 6 flowering and 6 non-flowering marijuana plants per registered consumer in a locked, enclosed indoor area. St. Louis County has not added stricter local rules.
Home cultivation is permitted statewide. Plants must be in a locked, enclosed area not visible to the public; outdoor cultivation is prohibited. The 6-plant cap is per registered consumer — a household with two adults may have 12 flowering and 12 non-flowering plants. Cultivation by tenants requires landlord consent. Sales of home-grown marijuana are prohibited.
Misdemeanor under state law for exceeding plant counts or selling; up to $1,000 county nuisance fine if odor/visibility violates neighbors.
