Description
Built on the storied Airborne G13/HP crossed with Genius, this feminized hybrid from Brothers Grimm Seeds carries the weight of serious genetics. The aroma layers damp earth and ripe fruit beneath a surprisingly clean minty lift, and the effect follows suit, delivering a high-THC experience in the 16-24% range that leans toward the psychedelic, cerebral and expansive rather than simply sedating.
G13 Genius is a rewarding photoperiod strain for growers who can give it the full run it deserves. Flowering spans 9 to 11 weeks, a window that suits indoor schedules nicely and gives outdoor cultivators a clear planning target. Medium plant stature keeps canopy management straightforward, making it practical in both tents and larger grow rooms. Indoor yields reach 450-600 g/m2, while well-tended outdoor plants can push 450-750 g per plant, figures that put it firmly in the high-yield tier. The feminized format removes any guesswork at sexing, letting you focus on maximizing each plant. If you are chasing both volume and a distinctive, complex high, this one earns a place in the rotation.

about this product
G13 Genius Feminized by Brothers Grimm Seeds delivers psychedelic potency and generous yields, everything you need to grow a genuinely memorable harvest.
G13 Genius leans firmly toward the cerebral and expansive end of the spectrum, with THC levels running between 16 and 24%. The effect is described as psychedelic rather than sedating, so expect an uplifting, thought-amplifying experience rather than a couch-lock finish.
The aroma builds through flowering with layers of damp earth and ripe fruit, rounded out by a surprisingly clean minty lift that sets it apart from more one-dimensional earthy strains. That same minty freshness carries through into the smoke, giving the overall profile a cool, complex finish.
It's rated easy to moderate, which places it comfortably within reach of intermediate growers who understand the basics of photoperiod management and can commit to its 9 to 11 week flowering window. Giving it the full run it deserves is what unlocks those high yields of up to 600g per square metre indoors.
Three feminised seeds is a practical entry point for growers who want to run a small dedicated crop and evaluate the genetics before committing to a larger run. Since all seeds are feminised, there's no need to account for males, so you can expect all three to produce flowering plants and yields in the 450–750g per plant range under good conditions.
