Airborne G13 S1 Feminised by Brothers Grimm Seeds is a legendary indica-dominant strain bred from a revered 30+ year-old clone with deep roots in cannabis history. Originally developed by Nevil Schoenmaker of The Seed Bank in Amsterdam and rumoured to trace back to a U.S. government research program, G13 is surrounded by mystery and myth, and this feminised version stays true to the legend.
This compact, fast-flowering plant is ideal for indoor growers and thrives in Sea of Green (SOG) setups. Flowering in just 55-60 days, Airborne G13 produces dense, resin-coated buds with a rich, classic hashish flavour that will satisfy old-school and modern connoisseurs alike.
Expect stable, vigorous growth, a medium height of 36-50 inches at 100 days, and reliable performance across multiple grows. These feminised seeds are a must-have for collectors of rare genetics and growers seeking a quick, high-quality indica-dominant harvest.
