Manufacturer Information
Genetics & Origin of G13 Genius XX
G13 Genius XX comes from Brothers Grimm Seeds. As the lineage, the breeder names an Airborne G13/HP clone that was crossed with a Genius pollen donor. Brothers Grimm describes the strain as a fast-flowering old-school line: predominantly Indica, with minimal stretch and bushy growth, and at the same time large, vigorous and robustly built. According to the breeder, all phenotypes reliably produced the desired citrus aromas. It does not give percentages or THC and CBD values; it calls the flowers very potent and resinous. The seeds are feminised and photoperiod, so flowering only begins after the light cycle is switched. Also from Brothers Grimm is Durban Nights XX; another strain with G13 in its name that we stock is G13 Haze by Barney's Farm.
Who Is G13 Genius XX For?
G13 Genius XX is a citrus Indica with vigorous growth. It suits:
- Fans of lemon and lime aromas
- Growers who prefer bushy plants with little stretch
- Yield-focused growers who appreciate long, dense colas
- Outdoor gardeners – the breeder reports very good results outdoors
- Consumers looking for a cheerful and at the same time relaxing effect
It is less suitable for anyone who wants to plan with fixed figures: Brothers Grimm does not put figures on yield, height and THC. You can find more strains from American breeders under US Genetics.
Growing G13 Genius XX: Indoor & Outdoor
Indoor Growing
Brothers Grimm gives two figures for the flowering time: 56 to 62 days and, elsewhere, 63 to 70 days. So plan for eight to ten weeks and time the harvest by the trichomes. After the switch to 12/12 the plants stretch only minimally and grow bushy and branched; according to the breeder, a central stake is generally enough as support. For feeding, it recommends starting flowering with a low to medium dose, feeding with a stronger emphasis on phosphorus in the later weeks and only watering in the final week. The manufacturer calls the yield very high, with large, extremely dense flowers and an excellent flower-to-leaf ratio – it does not give a figure in g/m². You can find more on feeding and climate in the Growpedia.
Outdoor Growing
Brothers Grimm recommends the strain for indoors and outdoors alike and reports many growers for whom it thrives very well outdoors. According to the breeder, the colas grow very long, with densely packed side flowers. The manufacturer does not state a harvest date, a height in centimetres or a yield per plant. Plan in enough space. Only grow where it is legal to do so.
Effect, Aroma & Terpenes of G13 Genius XX
Lemon and lime define scent and flavour: Brothers Grimm describes very resinous flowers with a citrus-fruit aroma that dominates the smoke. Elsewhere the breeder additionally names musky, incense-like and earthy notes. As dominant terpenes it lists myrcene, pinene and caryophyllene. Brothers Grimm describes the effect as cheerful and uplifting, yet still relaxing. The breeder regards the flowers as very potent; however, it does not state a THC value in per cent, nor a CBD value. So feel your way in cautiously – how intense the effect is depends on dose and individual tolerance.
