Scrog Screen Of Green

Screen of Green (SCROG) is a training classification describing a horizontal mesh or net screen positioned above cannabis plants to guide and distribute canopy growth across a flat plane. Breeders and cultivators working with this method typically employ plants with moderate to vigorous lateral branching habits, as the screen's primary function is to redirect vertical growth horizontally and maximize light penetration. The technique originated in commercial cultivation contexts where space efficiency and uniform canopy density were prioritized. SCROG systems are often paired with indeterminate or semi-indeterminate phenotypes that respond well to directional training without excessive stress. This classification reflects a cultivation methodology rather than a genetic trait, though certain lineages—particularly those with flexible stem structure and responsive internodal spacing—are freq

Breeders selecting for SCROG-compatible phenotypes often prioritize lateral branch development, stem flexibility, and predictable internode length. Genetic lines documenting consistent performance under screen training are valuable reference points for cultivators designing breeding programs around controlled-environment systems.
