Genetics & Lineage

Star Pupil seeds feature a rare genetic background incorporating Thai, Afghan, and Pakistani landrace influences. This unique lineage helped establish Star Pupil as a foundational Mass Medical Strains cultivar and earned recognition as High Times Flower of the Month in January 2017. The genetics are valued for their stability, distinctive expression, and robust growth traits.

Growth & Flowering

Plants grown from Star Pupil seeds typically reach medium heights and can approximately double in size during flowering. Strong branching and good stress resistance make these feminized seeds well suited to topping, training, and structured canopy development. Star Pupil performs well indoors and outdoors and benefits from an extended vegetative period to establish a strong framework.

Color & Appearance

Star Pupil seeds are known for producing highly colorful flowers that begin developing purple hues early in flowering, often between days 8–14. Colors can deepen to rich purple and nearly black tones in cooler conditions, while warmer environments may produce green highlights. Proper support with stakes or netting can help maximize lateral growth and light exposure.

Aroma & Flavor

Star Pupil seeds produce a distinctive terpene profile featuring sweet grape and floral perfume layered with earthy skunk and the signature “Pupil funk.” The flavor follows the aromatic profile, combining rich grape and floral notes with deep skunky undertones for a complex and memorable expression.

Cultivation & Seed Type

Star Pupil seeds are feminized cannabis seeds suited to indoor and outdoor growing. Plants respond well to training and structured cultivation, while allowing soil to dry thoroughly between waterings can encourage strong root development. With uniform growth, vivid coloration, sturdy branching, and unique terpene expression, Star Pupil seeds remain one of Mass Medical Strains’ signature varieties.
