Rooting Hormones
Rooting hormones are plant growth regulators—naturally occurring or synthetic compounds—that stimulate root initiation and development in cuttings and seedlings. In cannabis breeding and propagation, auxins (particularly indole-3-butyric acid, or IBA) are the primary active compounds, mimicking the plant's endogenous hormone signaling. These substances are applied as powders, gels, or liquid solutions to cut stem tissue, accelerating callus formation and root primordium development. Breeders and propagators use rooting hormones to improve cutting success rates, reduce propagation time, and preserve desirable phenotypes through clonal reproduction. The efficacy varies by application method, concentration, plant genetics, and environmental conditions such as humidity and temperature.

Rooting hormones are essential tools in clonal propagation programs, enabling breeders to rapidly multiply elite mother plants and maintain genetic consistency across generations. Reliable rooting techniques are critical for preserving phenotypes selected for specific terpene profiles, growth architecture, or cannabinoid ratios.
