A documented seed bank for licensed cannabis cultivators. Three generations of genetic lineage printed on a card inside every pack. Ten years of archives in Amsterdam.

Six strains shown below. Each one ships with a full genealogy card printed in Barcelona on the same press as pack #1 (2016). The catalog has 28 active SKUs in total.
Phenotype notes: stable across three test cycles (2021–2024). Average flowering 9 weeks. Yield: 480 g/m² indoor average. Lab analysis on file.
Every pack ships with a 6×9 cm cream card printed in Barcelona on the same press as the very first pack we sold in 2016. The card carries three generations of documented genetic ancestry.
This is the part that nobody else in the cannabis seed-bank category provides — not because they couldn’t print one, but because they don’t have the decade of archived lineage research behind it.
67% of repeat cultivator customers cite the lineage card as the reason they buy from us. The card is not marketing. The card is the product.
The lab sits in the Eixample district of Barcelona, two blocks from the Universitat de Barcelona where Joaquim Riera earned his plant-genetics PhD in 2015. Licensed under the Spanish cannabis research framework. Phenotype isolation, single-strain selection, F1 stability documentation on every lot.
Joaquim runs the bench weekly. Every seed lot that ships from Barcelona is selected and documented by him personally. Annual independent genetics audit by Bioenvision Madrid since 2024.
Founded Lineage in 2016 after eight years of cannabis genetics archival work that started as a personal project at Wageningen. Built the Amsterdam archive house-by-house, jar-by-jar. Runs the business, the catalogs, and every long-term genetic decision.
Reference: thinks cannabis genetics documentation is forty years behind wine grape clone documentation and is operating accordingly.
Joined Lineage in 2020 to open the Barcelona genetics lab. Runs every seed lot's stability cycle. Hand-draws the family-tree diagram printed on each pack’s lineage card. Published in Plant Reproduction and Theoretical and Applied Genetics.
Reference: spent his postdoc cataloging wild tomato landraces in Catalan agricultural archives before cannabis. Brings the same archival rigor.
Lineage genetics will be available to US-licensed cultivators in late Q4 2026, beginning with a single California partner. The lineage cards stay printed in Barcelona. The provenance documentation does not get outsourced.
