Seed Hardness
Seed hardness refers to the structural integrity and shell thickness of cannabis seeds, which affects germination reliability and storage longevity. Seeds with harder outer shells typically exhibit slower water absorption during germination, requiring longer soaking periods or scarification. This trait is often associated with landrace and heirloom genetics that evolved in harsh environments. Conversely, thinner-shelled seeds may germinate faster but can be more prone to mold or physical damage during handling and storage. Seed hardness is influenced by maternal plant genetics, growing conditions during seed maturation, and the age of the seed lot.

Breeders working with seed preservation and stability programs monitor shell thickness as a marker of seed viability and vigor. Selection for moderate seed hardness can improve storage shelf-life and reduce germination failure rates in commercial seed banking operations.
