Phototaxis
Phototaxis refers to the directional movement or growth response of cannabis plants in relation to light sources. Rather than a genetic family, phototaxis describes observable plant behavior—typically positive phototaxis, where shoots grow toward light, and negative phototaxis, where roots grow away from it. Understanding phototaxis is foundational in cultivation science, as light intensity, spectrum, and photoperiod directly influence plant architecture, flowering triggers, and secondary metabolite production. Breeders and cultivators leverage phototaxis knowledge to optimize canopy structure and yields under various growing conditions.

Breeders select for phototaxis responses when developing cultivars suited to specific environments—indoor systems with directional LED arrays, greenhouse conditions with variable natural light, or outdoor cultivation zones. Consistent phototactic behavior helps predict plant structure outcomes and enables more reliable phenotype stability across growing conditions.
