In 2025, most states that let adults grow cannabis at home cap households at six to twelve plants, usually with a tighter sub-limit on mature, flowering plants. A few states set higher or lower counts, and several states with legal cannabis still prohibit home cultivation entirely.

How plant limits are counted
Before comparing numbers, it helps to know what the numbers mean. Two states can both say "six plants" and still allow very different gardens.
home grow cannabis plant count limit
- Per adult vs per household: Some states write the limit per person 21 and older, then add a household ceiling. Others apply a flat cap to the residence no matter how many adults live there.
- Mature vs immature: Many laws split the count into flowering (mature) plants and vegetative plants or seedlings. A plant that starts flowering can suddenly count against a different number.
- Harvested flower: Plant counts are separate from possession limits. You can be under the plant cap and still over the legal amount of dried cannabis.
- Medical vs adult use: Registered patients often get a different count than recreational growers in the same state.
Adult-use states with home cultivation
These are the general statewide limits for adults 21 and older. Local ordinances can be stricter, so check your city or county rules as well.

Medical-only states with plant limits
Where adult-use sales are not yet running, home cultivation is usually tied to a patient registry.
- Hawaii: Registered patients may grow a limited number of plants, commonly 10, under the state medical program.
- Illinois: Qualifying medical patients may cultivate up to 5 plants.
- Oklahoma: Licensed patients may grow 6 mature plants plus 6 seedlings.
- Washington: Recreational home grow is not allowed, but some registered medical patients may cultivate a limited number of plants with authorization.
Legal states that still ban home grow
Legalization did not automatically include a right to cultivate. Delaware, Illinois, New Jersey, and Washington do not permit recreational home growing, and several medical-only states, including Florida, Pennsylvania, and West Virginia, bar patient cultivation as well. Always confirm the current rule with the state regulator, since programs are amended often.
What to check before you plant
- City and county rules: Many municipalities ban outdoor plants or lower the statewide count.
- Security and visibility: Most states require locked, enclosed, or screened growing areas that are not visible from public view.
- Landlord and HOA terms: A lease can prohibit cultivation even where state law allows it.
- Plant stage tracking: Label plants and note when they flip to flower, so you stay under the mature-plant cap.
- Gifting and sharing: Giving harvested cannabis away is usually capped and never a workaround for exceeding plant counts.
Common questions
Is 12 plants the maximum in most states?
Twelve per household is the most common ceiling among adult-use states that allow cultivation, but it is not universal. Maryland caps households at 2 plants, Montana at 8 mature plants, and Oregon at 4 for recreational growers.
Do medical patients get higher limits?
Often yes. States such as Colorado, Maine, and Oregon let registered patients or caregivers cultivate beyond the recreational count, sometimes with a physician certification or state registration.
Can two adults in one home each grow six plants?
Only if the state counts per person and the household cap allows it. In a 12-plant household state, two adults can typically reach that ceiling together, not 12 each.
Plant limits can change with each legislative session, and the rules that apply to your address may come from city hall rather than the state capitol. Confirm the current count with your state cannabis licensing agency before starting a garden.
