The rule, from the DCC
Ohio has no medical-specific home grow. Growing at home is an adult-use right, available to anyone 21 or older, patient or not. The Division of Cannabis Control's FAQ, citing ORC 3796.04 as renumbered by SB 56, sets these limits:
- up to 6 plants per adult;
- up to 12 plants per household with two or more adults;
- plants kept in a secured, enclosed area that people under 21 cannot access;
- the grow not visible from a public space;
- no hydrocarbon extraction at home;
- no selling what you grow.
We could not read the statute text directly, so these limits come from the DCC FAQ. Check it again before you buy equipment, since the law changed on March 20, 2026.
What this means for a Parma household
A patient aged 21 or older in a single-family house can grow within the adult-use limits like any other adult. A patient under 21 cannot grow at all, because the adult-use rules start at 21. A household of a patient and a spouse, both over 21, tops out at 12 plants, not 12 plus extra for the card.
The "not visible from a public space" rule matters on a street of close-set houses. A backyard plant that neighbors or passers-by can see from the sidewalk is a problem. A locked grow tent in the basement is the safer setup, and it handles the under-21 access rule too if there are teenagers at home.
Renters, note this: under ORC 3796.24 a landlord can ban home cultivation in the lease.
Need the recommendation part done?
In Ohio the physician starts your Registry file, so the visit comes first. Online evaluations are available for Ohio residents, and code DRWDY85872 takes 5% off. Registration itself is free.

Growing does not replace everything a card does. Patients skip the 10% adult-use excise on dispensary purchases, can buy four days' worth at once, and may possess up to a 90-day supply. Patients under 21 have no legal access without one. Our medical vs. adult-use comparison sets the two side by side.
One thing does not change: medical marijuana may not be smoked. Vaping is allowed on private residential property, which includes your house. The full method rules are on our Ohio patient rules page.
Getting registered from Parma
Parma is in Cuyahoga County, just south of Cleveland. The card process is statewide: a physician with a Certificate to Recommend enters your recommendation, and you activate it in the Registry for $0. The visit can be by telehealth.
The DCC's official dispensary map lists licensed stores. Dispensaries can sell seeds, clones and live plants, and the DCC FAQ lists a daily purchase limit of 6 of those.

Before you plant anything
Count the adults in your household, pick a spot that is enclosed, locked and out of public view, and if you rent, read the lease for a cultivation ban.
Questions people ask
Does my medical card let me grow more plants?
No. Ohio has no medical-specific home grow. Patients 21 and over may grow under the adult-use limits: 6 plants per person, up to 12 per household, according to the DCC FAQ.
Can my landlord stop me from growing?
Yes. ORC 3796.24 lets a landlord ban home cultivation in the lease.
