Every plant starts as a seed. Large scale hemp production is not possible without a consistent high-quality seed supply. Boulder Hemp has been breeding seed lines in Northern Colorado since 2014, using traditional breeding approaches and cutting-edge plant genome analysis methods–making us one of the most advanced hemp research and development programs in the world.

SAN CINCO
The San Cinco hybrid system is the result of selection for resistance to the windy summer storms of Colorado and certain types of insect pests. Although these stout plants are bred to survive, yields are also excellent for Colorado field grown plants and can exceed 2 pounds of dry flower that will contain 10%–15% CBDA. In Northern Colorado these plants begin to flower in the last days of July and early August and should be harvested before the first hard frost.
 
Boulder Hemp is releasing select high-yield feminized seed batches. Our hemp seeds can be started in the greenhouse about 28 days before field transplant date, or can be directly sown outside in appropriately prepared soil after the last frost.
All seeds are free of Y chromosomes, meaning more than 99% of mature plants will express only pistillate flowers.
All seed batches are tested for germination rates.
