// Definition
Rosin produced by pressing whole cannabis flower buds between heated plates with parchment paper. Yields typically range from 8–18% depending on strain, temperature, duration, and moisture content. While lower-yielding than pressing concentrated hash, flower rosin is the most accessible form of rosin production since it requires no pre-processing equipment.
// From the Episode
Soil Grown discussed optimal moisture content for pressing flower, noting that properly cured buds produce better results than bone-dry material because the moisture creates a steam distillation effect carrying resin outward. Mark Scialdone elaborated on the physics: even trace amounts of water turn to vapour above 100°C, and those fast-moving water molecules help transport the resin from the bud to the paper surface.
