Clone Banking

Clone banking refers to the preservation and storage of cannabis plant material through living cuttings maintained in vegetative growth. Unlike seed banking, which preserves genetic material in dormant form, clone banking maintains active plant tissue under controlled conditions—typically in grow rooms or specialized facilities. This practice is central to cannabis breeding and commercial cultivation, allowing breeders to preserve exact genetic copies of phenotypes without the genetic recombination that occurs in seed propagation. Clone banks require consistent environmental management, regular propagation cycles, and disease monitoring to maintain viability. The practice is particularly valuable for stabilizing desirable plant structures, growth patterns, and secondary metabolite profiles across multiple generations.

Breeders use clone banking to isolate and maintain stable phenotypes during multi-year selection programs, ensuring genetic consistency across breeding trials. This approach is essential for identifying and preserving elite mother plants that will be used repeatedly in controlled crosses.
