Description
Airborne G13 S1 Feminised from Brothers Grimm Seeds draws directly from the storied G13 lineage, one of the most mythologized indicas in cannabis history. The experience leans heavily toward the body, settling into a couch-lock calm that gives way to genuine sleepiness, making it a strain best saved for quiet evenings when there is nowhere to be.
As a feminised photoperiod plant, Airborne G13 S1 gives growers full control over the vegetative period, allowing you to size the plant to your space before triggering flower. The 7 to 9 week flowering window is a reasonable ask for an indica of this reputation, landing on the shorter end in ideal conditions and rewarding patient growers who push to that ninth week with fully developed, resinous structure. Indica dominance typically means a compact, bushy canopy that manages well in tents or constrained indoor rooms. Brothers Grimm Seeds has built a careful selection here, and for cultivators who value heritage genetics and a reliable feminised workflow, this one earns its place in the rotation.

about this product
Airborne G13 S1 carries legendary indica genetics into a beginner-friendly feminised package, ready for growers who want deeply sedating evenings on their own terms.
Brothers Grimm has built this strain to be genuinely approachable, rating it as easy difficulty, which makes it a solid first photoperiod project. Because it's feminised, you won't need to identify and remove male plants, and the medium height keeps things manageable in most grow spaces.
Airborne G13 S1 delivers a heavy, body-focused experience that trends firmly toward couch-lock and eventual sleepiness. With THC sitting in the 16–24% range, it's a strain best scheduled for late evenings when you have no obligations left in the day.
G13 is one of the most storied indica genetics in cannabis history, and Airborne G13 S1 is an S1 — a selfed feminised line that preserves those traits closely. Brothers Grimm's work here channels that classic earthy, woody character alongside the deep sedation the lineage has always been known for.
Indoors, expect around 350–450g per square metre after a flowering window of 7 to 9 weeks, which is a reasonable turnaround for an indica of this calibre. Individual plants can produce 200–450g depending on how much time you give them in the vegetative stage before flipping to flower.
