Pollen Banking

Pollen banking is the practice of collecting, preserving, and storing viable male pollen from cannabis plants for controlled breeding purposes. Breeders maintain pollen banks to preserve genetics from specific males, enable off-season crosses, and create reproducible breeding lines without needing to cultivate male plants year-round. Pollen remains viable for extended periods when stored properly in cool, dry conditions—often in refrigeration or freezer environments. This technique is foundational to modern cannabis breeding programs, allowing breeders to systematize crosses, maintain genetic records, and work with genetics that may not flower simultaneously. Pollen banking also reduces space requirements and simplifies the logistics of large-scale breeding operations.

Pollen banking enables breeders to conduct planned, controlled crosses on their own schedule and to preserve male genetics that express desirable traits. Many professional breeding operations depend on pollen banks to maintain consistent breeding protocols and to document parentage across multiple generations.
