Herbal Aspect, a cannabis company, has begun production of a new line of THC-free hemp strains under a licensing agreement with the Wisconsin Alumni Research Foundation (WARF), the company recently announced.
According to a release, the cultivars, known as Badger G, were developed by University of Wisconsin Researcher Michael Petersen. They are tailored for wellness, agricultural, recreational and industrial applications.
“This is a big step forward for us and for the cannabis economy in Wisconsin,” Herbal Aspect Co-Founder Matt Nelson said in a statement. “We’re proud to support locally developed science through WARF and UW–Madison. Badger G gives us a compliant, high-performing hemp line we can use in a wide range of future products and collaborations—without the legal or logistical barriers of THC.”
The company expects its first harvest of Badger G strains in early fall, with CBG-forward flower and infused products likely appearing in stores by October 2025.
Herbal Aspect will also be opening its fifth Madison-area dispensary at 3868 E. Washington Ave this summer.

Hello:
I am a Madison-based freelance writer who writes about cannabis issues for the Shepherd Express in Milwaukee. (Think of it as Milwaukee’s version of Isthmus.) According to what I have read, Dr. Michael Peterson was the researcher who helped develop a THC-free strain of cultivars for your firm called Badger G., and the Shepherd would like me to find out a little more about it for a possible article.
I know know Herbal Aspect and WARF were both involved in the development of Badger G and I have reached out to maybe the right Dr, Peterson (there seem to be several at the UW) and I was hoping someone at Herbal Aspect would be willing to talk about it as well.
Please let me know if you’re interested. I have a few weeks before my deadline, but would like to know sooner rather than later if there is anything here.
Many thanks for considering my request.
