Blacklung F1 (Mendobreath x Romulan) 6 Feminized Seeds

Romulan Genetics Blacklung (F1)

Blacklung (F1) is engineered for the “terpene champions” of the world—those who crave a profile that is unapologetically loud and remarkably complex. By crossing the frost-laden Mendobreath with the legendary Romulan backbone, Romulan Genetics has created a hybrid that is as much a sensory experience as it is a heavy-hitter.

The Profile: Loud, Acrid, and Elegant

Blacklung is a standout for extraction artists and flavor-chasers, boasting an impressive 4% terpene range even in varied growing conditions. The bouquet is a unique, contrasting fusion: sweet, delicate floral baby’s breath smashed against industrial notes of thick tar, earth, and pungent spice. It is a “viscous” smoke that coats the palate and demands attention.

The Experience

Despite its 75% Indica lineage, Blacklung offers a sophisticated high. It provides a state of profound relaxation and tranquility without the heavy “couch-lock” sleepiness often associated with potent Indica hybrids. It is the perfect choice for unwinding after a long day while remaining mentally present and elated.

Breeder’s Pro-Tips

Sexual Maturity: Romulan Genetics recommends growing these seeds in the vegetative stage until they reach full sexual maturity (visible stigmas/pistils) before flipping to a flowering light cycle.

Stabilization: For the highest quality results and consistency, stabilization through cloning is recommended. This best practice significantly reduces the risk of environmental stress-induced traits often found when rushing feminized seeds into flower. Always take cuts before flowering—you’ll want to keep the heavy-yielding phenotypes found in this progeny!
