Twenty20 Mendocino, has always taken the difficult path, the right path, the path less traveled. Their objective will never be to sell the most seeds but to create the finest product. This is not a race and their goal isn’t to win; their goal is to stand the test of time and maintain pride and craftsmanship in everything they do. As sure as the sun will rise, they pledge to never release seeds to the public that have not been grown, tested and approved by us. In a world of rapid-fire releases, social media hype and whimsical market demands, they promise to create our own path, march to the beat of their own drum, and always put quality over quantity.
