Based on the principles of lettuce seeds preservation. When trying to grow more than one lettuce variety for seed reproduction.
The bags are based on a synthetic material that has microscopic holes allowing for an even airflow to the lettuce, Additionally, the seeds don't fall out of the bag and can be easily collected.
Preserving Lettuce seeds:
Lettuce has perfect flower (both male and female in the same flowers). Flowers can cross pollinate (using animals), as well as self-pollination of flowers. Lettuce seed preservation bags prevent pollinators, especially bees and flies to reach the blossoms, preventing them from transferring the pollen between different varieties. Allowing conservation of more than one variety of lettuce at a time.
Drying bags for seed processing will help you in drying your seeds for the next season. The bags are based on a synthetic material that has microscopic holes allowing for an even airflow for a correct drying process. Seeds that are not dry have high respiration rate causing them to be less vigorous.
