G13 Genius - Brothers Grimm Seeds

Brothers Grimm crossed two famous and fantastic clone-only strains to create this incredible strong mostly Indica. It is for sure a superstrain of highest order that was created by using the 1990s Neville’s G13/Hashplant from 'The Seed Bank'. The pollen came from Silver-Thiosulfate reversal of MrSoul’s hammerstrain great strain called Genius.

Genius together with the outstanding Airborne G13/HP (which has a superb flavor profile of lemon/lime with a sour milk undertone) is a true winner: INCREDIBLE lemon/lime and sweet/sour flavors and aromas – you can not imagine how great this mostly Indica smells! The growth structure of the plants varies little bit but most are compact and bushy plants and they all share a citrus and sour flavor and aroma of highest order. G13 Genius has a great terpene profile and it is also very easy to grow, recommended for indoors and for greenhouse where you can expect big and fat plants.

Lineage: G13 Hashplant x Genius

Brothers Grimm Seeds: How a Classic Breeder Made a Strong Comeback

Brothers Grimm Seeds began in 1996 when Mr Soul and his partner Sly introduced their carefully bred cannabis strains to the grower community. Their name became known for stable hybrids and detailed genetic work. In 2002, production paused, but the original seeds and cuttings were preserved. The brand returned in 2015 with Duke Diamond joining in, and the seeds picked up right where they left off. Their lineup is rich in fruit tones, tropical hints, and sweet-scented plants with deep genetic roots.
