There are two main initiators of cannabis seed germination. “Imbibing” is the process whereby the seed soaks up water, which eventually results in the seed coat splitting. Seed coat hardness is variable with cannabis seeds. Ripe seeds should germinate but immature seeds are often not viable (usually a soft whiteness of a cannabis seed is attributed to immaturity, although some strains have this natural density and color). The second initiator of germination is light, which can penetrate the shell of seeds that have a weak or permeable coat. If the coat is not permeable by light or water, the seed may not be viable at all. Other inhibitors may include bad soil, incorrect pH level, seed exposure, seed depth, weeds, rich nutrient content, physical damage from animal or environmental causes, and fungi. Germination can take 12 hours to several weeks, depending on the seed structure and germination conditions.

The seeds are a lot darker than many of the seeds we have shown so far. Seeds can have lots of variation.
