Colas are clusters of buds that grow together at the tops of branches on female marijuana plants. Large colas are usually broken up during trimming so they can dry and cure evenly. Colas contain high concentrations of cannabinoids and terpenes and are the most potent parts of the plant. “This plant produced one massive cola, it must weigh 10 grams!” Colas form at the ends of branches where buds group together into dense clusters. They receive the most light exposure which promotes rapid growth and high cannabinoid levels. Colas typically grow one large bud at the top with smaller buds radiating off. The smaller buds underneath help support the main cola. Strategies like trellising spread out branches so more sites receive direct light to grow chunky, potent colas. More colas mean higher yields and more places for big buds to develop. During trimming, colas get broken up so they can dry and cure properly to avoid mold issues.
