Kosmic Kush or "Kandy Kush" is a potent indica-leaning hybrid of California staples, OG Kush and Train Wreck, and is known for its high yields of very large and resinous flowers. This specific phenotype was selected from a pool of 120 unique candidates by Allele Genetics. Elevated terpenes include limonene, caryophyllene, and myrcene.

The OG Kush mother in this cross brings a unique and pronounced sweet-pungent terpene profile, while the Train Wreck father contributes traits for high commercial yield, resin production, and lemony scents.
