Prohibited Hemp Varieties

For the 2021 growing season there are no prohibited hemp varieties in Ohio. The Ohio Department of Agriculture is providing the official testing results, from the 2020 growing season, to help cultivators in Ohio make informed decisions when selecting hemp varieties for the upcoming growing season. This data is based on the varieties as named by the licensee at the time of sampling during the 2020 growing season.

No endorsement, implied or otherwise, is made regarding any of the varieties named. All varieties require close monitoring and management for THC. Any given variety may produce higher THC unexpectedly due to fertilization, growing conditions and other environmental factors. 

Some varietal genetics have had several samples with THC levels in excess of the allowable limit. When cultivating a variety that claims to have a high CBD content, diligent monitoring should be used as many of those varieties tend to go hot if grown to full maturity.

For the purposes of this document, “Average THC Levels” takes into account the measurement of uncertainty. 

ODA encourages cultivators to review the prohibited variety lists from Kentucky and Pennsylvania and the Official Sample Results from Indiana and Michigan:
