Seed Size

Seed size refers to the physical dimensions of cannabis seeds, ranging from small (BB-shot scale) to large (pea-sized). Seed size is influenced by genetics, parent plant vigor, and growing conditions during seed production. Larger seeds often correlate with higher germination rates and seedling vigor in breeding programs, though smaller seeds are not necessarily inferior. Size alone does not predict cannabinoid or terpene profiles. Breeders track seed size as one indicator of seed maturity and quality during selection work. Understanding seed morphology helps cultivators and seedbanks assess viability before germination.

Professional breeders monitor seed size during hybridization projects as a marker of pollination success and genetic stability. Consistent seed sizing within a line often suggests environmental control and genetic uniformity across generations.
