tekkno ist grün is a hamburg-based collective that has been running open air techno events since 2011, making this their fifteenth anniversary edition. the event takes place on an open-air stage set within a green city park in the harburg district, a venue that holds up to 1500 people and has been the collective's home since they lost their original shipyard-adjacent site during the covid years.

the format is a single-stage afternoon-into-evening party running from mid-afternoon to 11pm, with the sound kept lower for the first two hours due to permit conditions before going full volume. the collective's name and ethos reflect a longstanding commitment to the surrounding parkland, with explicit expectations around keeping the grounds clean. the 2026 edition marks the anniversary with the same crew and format the series has maintained across its harburg run.
