Marijuana (Marihuana) Cultivation

Colorado Laws Regarding Marijuana Cultivation: How Much is Too Many?

While recreational and medical marijuana users (over 21 years of age) were previously permitted to grow 6 plants per person, Colorado law used to give allowances to people under certain circumstances to grow additional plants. This created a problem of large-scale cultivation on residential properties, creating both health and safety risks. It also made it easier for crime organizations to exploit the laws regarding Marijuana cultivation, resulting in an influx of crime and illegal distribution of the drug.


In order to combat this, House Bill 17-1220 took affect on January 1, 2018, which restricts the number of marijuana plants that both recreational an medical marijuana growers and caregivers can grow, imposing fines based upon the amount of plants found:

C.R.S. 18-18-406
(3) (a)(I) It is unlawful for a person to knowingly cultivate, grow, or produce a marijuana plant or knowingly allow a marijuana plant to be cultivated, grown, or produced on land that the person owns, occupies, or controls.
(II) (A) Regardless of whether the plants are for medical or recreational use, it is unlawful for a person to knowingly cultivate, grow, or produce more than twelve marijuana plants on or in a residential property; or to knowingly allow more than twelve marijuana plants to be cultivated, grown, or produced on or in a residential property.
(B) Except as provided in section 25-1.5-106 (8.5)(a.5)(I) or section 25-1.5-106 (8.6)(a)(I.5) for a medical marijuana patient or a primary caregiver with a twenty-four-marijuana-plant-count exception to subsection (3)(a)(II)(A) of this section, it is not a violation of subsection (3)(a)(II)(A) of this section if a county, municipality, or city and county law expressly permits the cultivation, growth, or production of more than twelve marijuana plants on or in a residential property and the person is cultivating, growing, or producing the plants in an enclosed and locked space and within the limit set by the county, municipality, or city and county where the plants are located.
