How Many Plants Can You Grow at Home Legally? US Limits
Most legal states allow 4 to 6 cannabis plants per adult, capped at 12 per household. See how state, medical, and local rules set your real limit.
How many cannabis plants you can legally grow depends on your state, not on a federal rule. There is no nationwide number because federal law still bans cannabis cultivation under the Controlled Substances Act. State recreational limits commonly range from 2 to 12 plants per household, and medical cannabis patients often may grow more than recreational users in the same state.

Recreational home grow caps for adults 21 and older vary widely. These are common limits, and lawmakers change them often, so confirm your current state statute before you plant.
What States Allow Home Growing of Marijuana
Several states allow no recreational home grow at all, including Washington and New Jersey. Washington permits medical patients to grow up to 6 plants, and up to 15 with a health care practitioner authorization. Florida allows medical use but not home cultivation.
Often yes, and the gap can be large. Illinois medical patients may grow up to 5 plants, Hawaii patients up to 10, and some states with no recreational grow still allow registered patients a small number of plants. A valid state-issued medical card is what makes the higher count lawful, and growing without that card falls back to the recreational limit, which may be zero.
How Many Plants Can I Grow with a Medical Card
Both limits can apply at the same time. A state might allow 6 plants per adult but cap the home at 12 total, so three adults in one house still cannot exceed the household ceiling. Some states also count only residents 21 and older, which means plants grown for a minor in the home can be unlawful even under a medical program.
Not always. Vermont allows 6 plants per adult but only 2 may be mature and flowering, and Connecticut and Rhode Island set similar mature-plant caps. Seedlings and clones sometimes count toward the total anyway, so keeping extra starts in a tray can push you over the legal number.
A state-legal plant count does not override a private lease or a local zoning code. Renters can be evicted for cultivation even when the plant count is lawful under state law.
No. Home grow limits cover personal use only, and sharing or selling surplus flower is a separate offense in every legal state. Exceeding a plant cap by a wide margin is often treated as evidence of intent to distribute rather than simple possession.
Penalties scale with the number of plants and your state's rules. Common outcomes include fines, misdemeanor charges, plant seizure and destruction, and felony exposure for large counts. Federal charges remain possible in theory, since cultivation is still illegal under federal law.
Check your state cannabis regulatory agency website and the county or city code for your address. If home grow is not permitted where you live, licensed retailers are the only legal source of cannabis products. Buying from a permitted store keeps you inside the law when a home grow is not an option.
