About the Club
We are BlattWerk — a Cannabis Social Club from Hildesheim
Founded from the conviction that cannabis can be grown responsibly, communally and legally. Since March 2026 we hold the official cultivation license — and we're building now.
Our Story
BlattWerk e.V. was founded in 2025 in Hildesheim — by a group of people who believe in a better approach to cannabis. Not illegal, not uncontrolled, but open, honest and within the Consumer Cannabis Act.
On March 18, 2026, we received our official cultivation license. That was a milestone — for us and for Hildesheim. Since then, we've been building our growing infrastructure. In summer 2026, we aim to present our first harvest.
We're not an anonymous club. Behind BlattWerk are real people with real names, committed to quality, transparency and community.
