About this release

 Frosty Rainbow is an indica-dominant hybrid that combines an exceptionally high resinous expression with a complex terpene profile moving between creamy, earthy, and subtly citrus notes. It presents interesting phenotypic variability, with expressions ranging from fruity candy to a citrus Z profile, bringing aromatic richness and versatility within the same genetic line. It emerges from the cross between White Rainbow (Medfarms Selections, Barcelona) and World Breeders Bubba, resulting in a modern genetics line clearly focused on premium flower production with high commercial value, where the balance between bag appeal, terpene profile, and structure plays a key role. White Rainbow, selected by Medfarms in Barcelona, is a highly recognized variety for its distinctive terpene profile, combining umami notes between creamy and citrus, bringing that "Z" character so sought after in today's market. It stands out particularly for its bag appeal, with cone-shaped flowers heavily covered in trichomes, and an aesthetic marked by bluish and orange tones. It is a parent strain clearly oriented toward premium flower production, where visual expression and aromatic complexity define its value. World Breeders Bubba provides the classic indica structural base, with compact, robust plants and dense flowers, offering stability, homogeneity, and solid yields. On the aromatic side, it introduces a deeper and more enveloping layer, with earthy, spicy, and creamy notes that add body and persistence to the final profile. In combination, both parent strains produce a genetics line that maintains the structure, density, and reliability of Bubba, while incorporating the bag appeal, resin load, and modern terpene expression of White Rainbow. The result is a variety with a creamy-citrus Z-type expression, accompanied by fruity candy nuances over a darker, earthier background, achieving a balanced, complex, and highly commercial profile.
