Growing marijuana plants at home is illegal anywhere in Knoxville under Tennessee state law. Home cultivation of industrial hemp requires a state license and is generally limited to commercial agricultural operations.
Tennessee Code 39-17-417 makes manufacture of marijuana, including cultivation, a Class E felony for one-half ounce or more, with lower amounts treated as misdemeanors. There is no home-grow exception, even for personal use or registered medical conditions. The narrow CBD oil program does not authorize cultivation. Industrial hemp growing requires a license from the Tennessee Department of Agriculture under TCA 43-26-101, with background checks, GPS coordinates, and inspections; it is rarely practical for residential properties. Knoxville zoning would also restrict commercial agriculture in most residential districts. No personal cultivation limit exists because all cultivation is barred.
Home marijuana cultivation can result in felony charges, asset forfeiture, and federal exposure. Unlicensed hemp growing can trigger crop destruction and civil penalties from state agriculture inspectors.
