Genetics & Origin of Black Widow
According to Mr. Nice's account, Black Widow is not an imitation but the original: the strain descends directly from the original parents of the famous White Widow and was developed further by Shantibaba under the umbrella of the Mr. Nice Seedbank. A Brazilian Sativa and a South Indian Hybrid were crossed; the breeder lists the result as an Indica-dominant hybrid and does not state exact proportions. As early as 1995, the strain received an award at the High Times Cannabis Cup. According to the breeder, the mixture of Sativa growth and Indica flower structure is characteristic. Black Widow is photoperiod and available as regular seed: the seeds produce male and female plants, which makes it interesting for selection, mother plants and your own crosses. Mr. Nice does not state a THC value in per cent. For comparison, the shop also stocks White Widow by White Label Seed Co.
Who Is Black Widow For?
Black Widow is a strain for everyone who is looking for classic genetics with history and would like to do their own selecting. It suits:
- Collectors of classic strains with a well-known pedigree
- Selectors who want to choose a mother plant from regular seeds
- Hobby breeders who use male plants for their own crosses
- Extraction fans who would like to process frosty, resinous buds further
- Consumers who appreciate a relaxing effect with a clear head component in the evening
If you want only female plants without any selection work, a feminised strain is the better choice. You can find more regular lines under Classics and Landraces.
Growing Black Widow: Indoor & Outdoor
Indoor Growing
Indoors, according to Mr. Nice, Black Widow flowers for about 8 to 10 weeks and yields 350 to 450 g/m². The strain works in soil as well as in hydroponics. The resin development is striking: above all in the second half of flowering it gains strongly in trichomes, and the breeder speaks of a trichome explosion in the final weeks – so do not harvest too early. Mr. Nice does not state a height; because of the Sativa growth described, a little headroom makes sense. As these are regular seeds, it is best to germinate more seeds than the number of plants you want to keep and determine the sex in pre-flowering; male plants are removed if pollination is not wanted. You will find the basics in the Growpedia.
Outdoor Growing
For open ground and greenhouse, Mr. Nice states a harvest from late September to early October in the northern hemisphere and 300 to 400 g per plant. The breeder describes strong growth but points out that a rainy end to flowering can reduce the yield. A sheltered spot or a greenhouse is therefore the safer choice in damp autumn locations. You can find more strains for outdoors under regular outdoor seeds. Only grow where it is legal to do so.
Effect, Aroma & Flavour of Black Widow
Mr. Nice describes the scent as spicy and sweetish with the classic White Widow sharpness, and the flavour as earthy-woody with a sweetish, resinous note. According to the breeder, the intensely resinous scent develops further during drying and curing. It does not state a lab terpene profile. On the effect it says: physically relaxing with a cerebral note, powerful without being overwhelming – a classic hybrid effect with a clear head component and a relaxing base, which Mr. Nice recommends for the evening hours or creative projects. The breeder gives the THC content only as high; a percentage figure is missing. With regular seeds, individual plants can also differ from one another. How intense the effect is depends on phenotype, dose and individual tolerance.
