- Hemp research programs authorized through December 31, 2021: On December 21, 2020, Section 782 of the Consolidated Appropriations Act, 2021 extended the authority of states to operate hemp research programs through December 31, 2021.
- Hemp emergency rule effective October 29, 2020: Learn more about the new emergency rule that extends the current hemp program until December 31, 2021.
- Harvest notification form: You must notify DATCP 30 days before you harvest each lot of hemp so DATCP has time to schedule testing. Use the online process at MyDATCP to submit your 30-day harvest notifications.
- Sampling: Your lot of hemp must contain 15 or more female plants in order for DATCP to take samples for testing. The regulatory sample must be taken before you can harvest each lot of hemp, and is a collection of the top two inches of flower from at least 15 female plants per lot. The exact number of cuttings per lot varies based on the size and the uniformity of a lot.
- Submit documents online: You can no longer email location changes, planting reports, or 30-day harvest notifications. If you have a hemp license and a 2020 annual registration, you can submit these documents using MyDATCP.
Hemp Research Program
DATCP's Hemp Research Program requires both hemp growers and processors to obtain one-time licenses, and register each year they intend to plant and/or process hemp. Growers and processors must also pass criminal background checks and pay fees to participate in the program. As participants in the research program, growers and processors are required to:
- Destroy crops that test higher than 0.3% total delta-9 THC, as determined by regulatory testing.
- Obtain a hemp grower or processor license.
- Pay for and pass a criminal background check before the initial license is issued.
- Pay license fees and/or annual registration fees.
- Submit a signed research agreement and a research summary.
- Hemp growers: Submit a variety notification and approval form at least 30 days prior to planting to obtain approval for that variety from DATCP.
- Hemp growers: Submit a planting report by July 1 within 30 days of planting hemp at each lot*.
- Hemp growers: Submit a harvest notification form at least 30 days before harvest.
- Submit a destruction notification form prior to voluntary destruction of hemp that is not otherwise ordered destroyed by DATCP.
- Provide access to DATCP hemp inspectors to obtain a hemp sample for each lot*.
- Pay a $250 sampling fee for each lot* sampled by DATCP.
- Submit a final production/processing report at the end of the growing season and prior to registering for the following growing season.
*A contiguous area in a field, greenhouse, facility, or growing structure containing the same variety or strain of hemp throughout the area.
There is inherent risk associated with participation in a research program focusing on a new crop and with participation in this research pilot program. There is no guarantee that your crop will pass the regulatory THC test.
