Genetics & Origin of Killer Queen XX
Killer Queen was originally created by Vic High, a breeder at the BCGA: he pollinated the Airborne G13/HP clone with a Cinderella 99 male from Brothers Grimm. The XX version is the feminised edition of this cross. For it, Brothers Grimm used silver thiosulphate to make its best C99 female produce pollen; because this pollen carries only X chromosomes, it gives rise exclusively to female seeds, according to the breeder. The strain is photoperiod and is listed by the breeder as a hybrid; it is considered Indica-leaning, and a share in per cent is not given. Brothers Grimm does not state THC and CBD values. The breeder counts Killer Queen among the outstanding plants in its collection. You will also find the father line in our range as Cinderella 99; another XX strain from the house is G13 Genius XX.
Who Is Killer Queen XX For?
Killer Queen XX is a fruity classic in feminised form. It suits:
- Fans of Cinderella 99 and G13 genetics
- Growers who work in a Sea of Green or with a net (SCROG)
- Lovers of fruity aromas from black cherry to Hawaiian Punch
- Indoor growers who plan for around eight to nine weeks of flowering
- Consumers looking for a balanced effect of euphoria and relaxation
It is less suitable if you cannot or do not want to support the plants – the breeder expressly recommends staking. You can find more strains of this type under Indica strains.
Growing Killer Queen XX: Indoor & Outdoor
Indoor Growing
Brothers Grimm gives two slightly different figures for the flowering time: 60 to 65 days and 56 to 63 days. So plan for around eight to nine weeks after the switch to 12/12 and go by the ripeness of the trichomes. The breeder calls the plant robust and recommends it for SOG and SCROG. It advises removing the lower branches and supporting the heavy flowers with stakes or a net. The breeder does not state a plant height in centimetres. As the indoor yield, Brothers Grimm states 114 to 230 g without saying what the value refers to; there is no yield in g/m². You will find the basics on training and climate in the Growpedia.
Outdoor Growing
For open ground, Brothers Grimm gives no figures but an image: outside, the plants could rival a Christmas tree. That points to large plants that need space and sturdy supports. The breeder does not give a harvest date or a yield per plant. A sunny, airy spot is the safe choice; whether the flowers ripen before the wet autumn depends on your region. Only grow where it is legal to do so.
Effect, Aroma & Terpenes of Killer Queen XX
According to Brothers Grimm, Killer Queen XX is said to reliably produce all the fruity flavours of the original Killer Queen – the breeder cites a range from black cherry to Hawaiian Punch and describes the aroma as sweet and fruity. It gives myrcene, limonene and caryophyllene as the dominant terpenes, though without percentages; a complete lab profile is not available. Brothers Grimm describes the effect as balanced – euphoric and relaxing at the same time. The breeder does not state a THC value, and we do not add an estimate. According to Brothers Grimm, the flowers grow large and resinous. Start with a small amount: how intense the effect is depends on phenotype, dose and individual tolerance.
