The newest addition of female seeds to our tester category is Genius x Rosetta Stone, created by Breeder Rick Campanella, aka, MrSoul. These iconic Brothers Grimm strains have merged to create a new 2023 variety on the Brothers Grimm Seeds tester seed menu. Rosetta Stone is the female pollen donor, and she is famed for winning the 2018 High Times Top 10 Strain Award. Genius is the notorious parent of Apollo.

For a good laugh, Breeder MrSoul recounts sharing some of his Genius product with SubCool back in the day.

Grow Genius x Rosetta Stone and compare your notes with us later in the year. If you’re new to learning about our tester seed category, then all you need to know is that we are still testing these strains to determine two primary things. First we are testing for stability across many growing environments and methodologies and then we asses customer appreciation. Thanks for growing with us. Keep growing with the Brothers Seeds Grimm family and let us know how your garden goes on Instagram or Facebook.
