New cannabis seed fest ‘Terpnami’ hits San Francisco Dec. 7-8

The West Coast is the cannabis genetics innovation center of the globe. And yet it lacks a full-service summit in a major city in December, when the full-sun seeds are ready, wallets are fat, and growers are thinking about what to grow the next year. This problem ends in 2024 with Terpnami. Get tickets, view the Show Guide, and Seed Catalog.

Why a seed show in The City?

  • Cannabis is a $60 billion a year US industry. 
  • The West Coast is the global epicenter of cannabis innovation.
  • Early winter is a key milestone in the growing year. The full-sun harvest seeds are ready, wallets are full before Christmas, and growers are gathering seeds for their 2025 run.
  • Now that cannabis seeds are legal under the Farm Bill, San Francisco offers world-class amenities for a seed expo that’s centrally located and globally accessible.

Award-winning cannabis journalist and best-selling author David Downs said SF Weed Week and SF Hash Week showed how weed growers and hashmakers are rock stars with their own devoted fanbases. Terpnami completes a trio of annual city cannabis celebrations.

“Everything in cannabis starts with great genetics and I’m honored to celebrate the breeders. Breeders are rockstars and deserve to be celebrated in a world-class city with a top-notch event. San Francisco in December is the perfect place for the cannabis genetics world to get together every year,” Downs said.
