Plant Structure Types

Plant structure refers to the physical architecture and growth pattern of cannabis plants, which breeders classify into distinct phenotypic categories. Common structural types include indica-leaning (compact, bushy growth), sativa-leaning (tall, open branching), and hybrid expressions that blend these traits. Structure is determined by genetics, though environmental factors like light, spacing, and training modify final form. Understanding structural classifications helps breeders select parent plants for specific cultivation goals—high-density canopies, vertical growth, or balanced frameworks. Lineage records frequently document structure type alongside cannabinoid and terpene profiles to guide breeding decisions.

Breeders prioritize plant structure when selecting parents for specific cultivation environments and yield targets. Compact structures suit small spaces and dense planting, while vigorous vertical growth appeals to outdoor and high-ceiling systems; hybrid structures offer flexibility across production methods.
