Open Flower Structure
Open flower structure refers to cannabis plants that develop visibly spaced, airy bud formations with notable gaps between calyxes and leafy material. This trait contrasts with dense, tight bud phenotypes and is influenced by genetics, internode length, and environmental factors during flowering. Breeders working in this category often select for this architecture to improve air circulation within the canopy, potentially reducing moisture retention in the flower zone. Open structure is frequently associated with certain landrace and sativa-dominant lineages, though it can appear across diverse genetic backgrounds. The trait has practical implications for cultivation practices and is documented in phenotype records across many breeding programs.

Breeders intentionally select for or against open flower structure depending on cultivation environment and market goals. Growers in high-humidity regions may prioritize open phenotypes for disease prevention, while others breed toward density for yield presentation.
