Mature cannabis seeds typically exhibit a hard, oval shape, reminiscent of a teardrop. Their coloration generally ranges from light tan to dark brown, often displaying mottled or tiger-striped patterns. A pronounced ridge or seam runs along one side, which is the point from which the seedling will emerge. Healthy specimens are firm to the touch and possess a waxy sheen. Immature or unviable ones are often pale green or white, and crush easily under pressure.
The appearance of these propagules is crucial for cultivators as it directly relates to germination success and subsequent plant health. Recognizing the characteristics of viable versus non-viable seeds allows for efficient resource allocation and minimizes wasted effort. Historically, visual inspection has been a cornerstone of cannabis cultivation, passed down through generations of growers to identify promising genetic potential.
