Cultivation Lives Inside the Possession Statute
Many states draft cultivation as a stand-alone offense with its own threshold tiers. Indiana does not. IC 35-48-4-11 rolls three behaviors into a single criminal section:
- Knowingly or intentionally possessing marijuana, hashish, hash oil, or salvia (subsection (a)(1)).
- Knowingly or intentionally cultivating marijuana (subsection (a)(2)).
- Knowingly failing to destroy marijuana plants growing on premises the defendant owns or controls (subsection (a)(3)).
All three are punished identically. There is no “personal-use grow” tier, no plant-count exception, no medical exception, and no allowance for outdoor “volunteer” plants from prior seed. The Republican-supermajority legislature has not opened any of these doors.
A person who knowingly or intentionally cultivates marijuana commits possession of marijuana, hash oil, hashish, or salvia, a Class B misdemeanor.
Indiana Code § 35-48-4-11(a)(2)
The One-Plant Class B Misdemeanor
A single living cannabis plant on a Hoosier windowsill is, on its face, a Class B misdemeanor — up to 180 days in jail and a $1,000 fine, plus mandatory court costs and a one-year driver’s license suspension under IC 9-30-4-6. With a prior drug conviction (any controlled substance, any state), the same plant becomes a Class A misdemeanor (365 days, $5,000). With a prior plus 30 grams of harvested marijuana sitting on the same premises, it becomes a Level 6 felony (6 months to 2.5 years prison, $10,000).
| Scenario | Class | Maximum Sentence |
|---|---|---|
| 1 living plant, 1st offense | Class B misdemeanor | 180 days, $1,000 |
| 1 living plant, prior drug conviction | Class A misdemeanor | 365 days, $5,000 |
| Plants + 30g harvested, prior conviction | Level 6 felony | 6 mo – 2.5 yrs prison, $10,000 |
| Larger grow operation (typical charging) | Level 6 / Level 5 felony (dealing) | up to 6 yrs prison, $10,000 |
Larger grows are almost always charged as dealing-by-manufacture under IC 35-48-4-10.
“Failure to Destroy” — The Outdoor Plant Trap
Subsection (a)(3) is a quiet but consequential clause. Knowingly failing to destroy marijuana plants growing on premises a person owns or controls is itself a chargeable offense at the same Class B misdemeanor baseline. In practical terms, an owner who discovers a wild or volunteer cannabis plant on their property and does not remove it can be prosecuted — though in practice charges almost always require an additional indicator of cultivation intent (irrigation, lighting, fencing). The provision functions as a backstop that prevents “they were just growing wild” defenses.
Larger Grows Become Dealing-by-Manufacture
IC 35-48-4-10 defines “manufacture” to include cultivation undertaken for distribution. Once a grow operation crosses into dealing territory — multiple plants, harvested product packaged for sale, lighting and ventilation infrastructure suggesting commercial production — prosecutors charge under the dealing statute, where the 10-pound (or 300-gram concentrate) threshold triggers Level 5 felony exposure (1–6 years prison, advisory 3 years).
The Level 5 enhancements that apply to retail dealing also apply to manufacturing: school-zone, park-zone, substance-abuse-facility-zone, firearm presence, and hemp-mimicry packaging. A grow inside a 500-foot school radius elevates a Level 6 felony to Level 5, regardless of whether children were ever present.
Why “Just Three Plants” Is Not a Defense
Several legalization states allow personal-use cultivation up to a defined plant count (Michigan: 12; Colorado: 6; Illinois: 5 only for medical patients). None of those exceptions apply in Indiana. Carrying a Michigan medical-cardholder ID or a Michigan adult-use receipt provides no protection at all on the Indiana side of the line. The Indiana statute reaches any plant of any size at any maturity stage, and federal Schedule I status overlays the state offense.
Hemp Cultivation Is a Separate Regime
Industrial hemp under 0.3% delta-9 THC is governed not by IC 35-48-4 but by IC 15-15-13, with regulatory authority at the Office of Indiana State Chemist. Licensed hemp producers may grow the plant for fiber, grain, and cannabinoid extraction. THC test failures during cultivation must be destroyed under USDA rules; deliberate cultivation of high-THC plants under a hemp license can fall back into IC 35-48-4 criminal exposure.
Forfeiture Risk for Property
Indiana’s civil-forfeiture chapter, IC 34-24-1, lets prosecutors seek to seize real property used to facilitate a controlled-substances offense. Cultivation cases are the prototypical real-property forfeiture vehicle: a grow operation in an owned home, garage, barn, or rural outbuilding can support a forfeiture action against the structure itself. Timbs v. Indiana (2019) provides Eighth Amendment proportionality review, but the doctrine is enforced case-by-case rather than categorically.
