Genetics & Origin of Double Black
Double Black is a homage to Black Domina 98: G13 Labs gives the genetics as Black Domina 98 × Black Domina 98, so the same line stands on both sides of the cross. The Indica character is correspondingly pronounced. The breeder's data sheet states 100% Indica, while elsewhere around 90% is mentioned – in any case it is an almost pure to pure Indica. G13 Labs gives the THC content as 16 to 18%; the manufacturer does not state a CBD value. The plants grow compact and bushy and produce so much resin that it is noticeable even when repotting. The seeds are feminised and photoperiod, so flowering only begins after the light cycle is switched. If you are looking for Black Domina as a regular strain from another breeder, you will find Black Domina Regular by Sensi Seeds in our range.
Who Is Double Black For?
Double Black is a compact, resin-rich Indica with short flowering. It suits:
- Indica lovers looking for a heavy, body-focused effect
- Fans of Black Domina 98 who are looking for this line in concentrated form
- Growers who work in SCROG or in a Sea of Green
- Those interested in resin who value heavily coated flowers
- Outdoor gardeners who want to harvest in early October
It is less suitable for anyone looking for a stimulating, clear-headed strain for the daytime. You can find more strains with short flowering under High Yield & Short Flowering.
Growing Double Black: Indoor & Outdoor
Indoor Growing
G13 Labs gives the flowering time indoors as 55 to 60 days, i.e. around 8 weeks from the switch to 12/12, and states 500 g/m². According to the breeder the plants stay compact and bushy; it does not state a height in centimetres, and with us the strain is classified indoors in the class 60 to 110 cm. The stocky growth goes well with SCROG and Sea of Green, but the strain can also be grown in a pot without training. Resin-rich flowers benefit from good air movement and controlled humidity in the final weeks. You will find the basics on both growing methods in the Growpedia.
Outdoor Growing
Outdoors, G13 Labs gives early October as harvest time and 1,000 g per plant. The plants grow medium-sized outdoors; the breeder does not give a figure in centimetres, and with us the strain is classified in the class 100 to 160 cm. A yield of this order requires plenty of root space, full sun and a long vegetative phase. Support the side branches in good time and make sure of an airy location in autumn. Only grow where it is legal to do so.
Effect, Aroma & Flavour of Double Black
G13 Labs gives the flavour as sweet and Afghan-influenced, with notes of mango and peppermint. The scent is described as sweetish, spicy and slightly musky. The manufacturer does not give a lab terpene profile. The breeder sums up the effect as deep relaxation and an inspiring moment; it is considered heavy, warm and body-centred, almost meditative – a strain for switching off. According to G13 Labs the THC content is 16 to 18%. Even though that is not a top value, the physical effect of such an Indica-heavy strain can be pronounced. How intense it is in an individual case depends on dose and personal tolerance.
