The Oklahoma Department of Agriculture, Food, and Forestry (ODAFF) regulates industrial hemp cultivation with strict guidelines, including a THC limit of 0.3% on a dry weight basis and a negligent violation threshold at 1% THC. Licensing deadlines require applications by July 1st for outdoor grows and December 1st for late harvests. Fees include a $500 non-refundable license application and inspection charges based on acreage or square footage. Exceeding THC limits can result in fines up to $10,000 per day and possible criminal prosecution under Oklahoma hemp laws.
