5. Texture (Smooth, Waxy)
The tactile characteristic of cannabis seeds, typically described as smooth and waxy, represents a key component in visually assessing seed quality. This texture arises from a thin, protective layer covering the seed’s exterior. This layer primarily functions to retain moisture within the seed, preventing desiccation and ensuring embryo viability. A seed lacking this smooth, waxy coating often indicates damage, immaturity, or improper storage, all of which negatively impact germination potential. Observing the seed’s surface under magnification reveals a slightly reflective quality due to the waxy component, further confirming its presence. Seeds exhibiting a rough, cracked, or dull surface texture are often discarded as non-viable, underscoring the texture’s crucial role in visual selection.
The practical implications of assessing seed texture extend to storage and handling protocols. Seeds with a smooth, waxy surface are less susceptible to physical damage during handling and are better equipped to withstand fluctuating humidity levels. Proper storage in airtight containers helps preserve this protective layer, maintaining optimal seed quality over extended periods. In contrast, seeds with a compromised texture are more vulnerable to fungal infections and require stricter environmental control to prevent deterioration. Seed banks and commercial cultivators implement rigorous quality control measures, including visual inspection for texture, to ensure consistent germination rates and reliable crop yields. The tactile feedback during handling also provides experienced growers with a subtle, yet valuable, indicator of seed health.

9. Maturity (Darker Coloration)
Darker coloration in cannabis seeds serves as a key visual indicator of maturity, a crucial component in determining the overall quality and viability of cannabis propagules. The progressive darkening of the seed coat during development reflects the accumulation of pigments and hardening of the outer layers, processes directly linked to embryo maturation. Lighter-colored seeds often indicate premature harvesting or incomplete development, resulting in reduced germination rates and diminished seedling vigor. Therefore, the presence of a dark brown or near-black hue is generally considered a positive attribute when assessing “what do weed seeds look like” in the context of selecting viable candidates for cultivation. This connection, linking visual appearance with physiological development, is fundamental to effective seed selection practices.
Consider a scenario where a grower harvests cannabis flowers prematurely. The resulting seeds are likely to exhibit a lighter tan or greenish tint, lacking the characteristic dark coloration of fully mature specimens. Planting these lighter-colored seeds typically results in lower germination success, with many failing to sprout or producing weak, underdeveloped seedlings. Conversely, seeds harvested from fully ripened flowers, exhibiting a rich, dark brown color, demonstrate significantly higher germination rates and produce robust, healthy seedlings. This direct correlation underscores the practical importance of assessing seed color as an indicator of maturity. Furthermore, variations in color intensity can provide clues about the plant’s health during seed development; nutrient deficiencies or environmental stressors may lead to uneven or lighter coloration, suggesting compromised seed quality.
In summary, darker coloration serves as a reliable visual marker of maturity in cannabis seeds and a critical element in determining “what do weed seeds look like” from a quality perspective. This characteristic is directly linked to germination success and seedling vigor, making it a valuable criterion for seed selection. Challenges exist in differentiating subtle shades of brown, requiring experience and careful observation.
