Plant Architecture Types

Plant architecture describes the physical structure and growth pattern of cannabis plants, encompassing traits like height, branching density, internode spacing, and canopy shape. Breeders classify plants into broad categories—such as tall/columnar, compact/bushy, or balanced morphologies—to predict cultivation requirements and optimize yield potential in different growing systems. These structural traits are influenced by both genetics and environmental conditions, making architecture a key consideration in breeding programs targeting specific production environments. Understanding plant architecture helps growers select cultivars suited to indoor vertical systems, outdoor field production, or greenhouse cultivation. Documentation of architectural phenotypes within strain families enables more predictable outcomes across generations and growing conditions.

Breeders actively select for specific architectural traits to create cultivars tailored to high-density indoor farming, SOG (sea of green) operations, or outdoor cultivation. Plant structure directly impacts light penetration, air circulation, pest/disease management, and labor efficiency, making it a primary breeding objective alongside potency and terpene profiles.
