Introducing Airborne G13 S1 Feminized Seeds by Brothers Grimm. An indica-dominant strain, bred for quality and consistency.

Brothers Grimm proudly introduces Airborne G13 S1 Feminized Seeds, crafted from a prized 30+ year-old clone carefully preserved and worked by renowned breeder MrSoul. This classic strain is an indica-dominant, fast-flowering plant that stays compact while producing dense, resin-coated buds with rich, hashish-like flavors.

Highly stable genetics and a history of use in MrSoul’s breeding projects make Airborne G13 a reliable choice for growers seeking quality and consistency. Originally a clone-only strain bred by Nevil Schoenmaker of “The Seed Bank” in Amsterdam, Airborne G13 carries a legendary lineage.

Though shrouded in mystery, G13 is believed to be an indica-dominant hybrid, rumored to have originated from a U.S. government research facility in Mississippi — adding to its mystique.

Airborne G13 Growing Tips:

– Reaches a height of 36 to 50 inches at 100 days

– Naturally compact and ideal for indoor cultivation

– Fast flowering time: ready in approximately 55 to 60 days

– Performs exceptionally well in Sea of Green (SOG) setups

If you’re looking for a low-maintenance, high-quality indica-dominant strain with a legendary background, Airborne G13 delivers.
