Mature cannabis seeds typically exhibit a hard, oval shape, measuring approximately 2-7mm in length. Their coloration usually ranges from light tan or grey to dark brown or nearly black, often displaying mottled or tiger-stripe patterns. A pronounced ridge or seam runs along one side of the seed, indicating the point where it was attached within the flower. The surface is generally smooth and waxy to the touch, providing a degree of protection for the embryo within.
Proper identification of viable cannabis seeds is crucial for successful cultivation. Visual inspection allows cultivators to assess the seed’s maturity and potential for germination. Darker seeds, with a hard outer shell and defined markings, are generally considered more likely to sprout. Conversely, pale, soft, or cracked seeds are often deemed immature or damaged and less suitable for planting. The external appearance offers a preliminary, non-destructive method of evaluating seed quality.
