Rooting Hormone

Rooting hormone refers to naturally occurring plant compounds or synthetic auxins applied to cuttings to accelerate root development. In cannabis breeding, these substances—whether powder formulations, gels, or liquid concentrates—help propagate clones from mother plants by stimulating cell differentiation at the cut site. Breeders and cultivators working with vegetative propagation commonly use rooting hormones to improve clone survival rates and reduce establishment time. The practice is standard in maintaining elite genetics or preserving phenotypes that cannot be reliably reproduced from seed. Rooting hormone application is a cultivation technique rather than a strain trait, but understanding its use is relevant to clone-based breeding programs.

Breeders maintaining clone libraries rely on rooting hormones to preserve genetics between breeding cycles and ensure consistent propagation of valued phenotypes. Efficient cloning protocols using rooting aids reduce the number of mother plants needed and accelerate the timeline for phenotype selection and stabilization.
