Sirius Black Strain Information and Characteristics
-
Strain Type:
Sirius Black is an indica-dominant hybrid with dense, resinous buds. You will notice a leaning toward sedative body effects.
-
THC Content:
THC averages between 22% and 26% across runs. Expect potent highs that suit experienced users looking for strong effects.
-
CBD Content:
CBD remains below 1% in most pheno types. Its low CBD makes it better for symptom relief tied to THC than for CBD-only therapy.
-
Grow Difficulty:
Growing Sirius Black requires intermediate skill and steady upkeep. You will need attention to feeding, pruning, and pest checks to reach peak yields.
-
Flowering Time:
Indoor flowering completes in 8 to 9 weeks. Outdoor harvest falls in mid to late autumn in temperate regions.
-
Expected Yield:
Yield ranks high when you train and feed properly, with 400 to 550 g/m2 indoors. Outdoor plants deliver solid per-plant weights in good soil and warm summers.
-
Plant Height:
Plants stay medium in height, typically 80 to 140 cm indoors. You can use low stress training to keep them compact in small rooms.
-
Growing Environment:
Sirius Black performs well indoors under controlled light and ventilation. Outdoors it finishes before heavy frost in temperate zones.
-
Expected Effects:
Effects start with a warm body relaxation and move into calm mental focus. Later use often leads to sleep onset for those with insomnia.
-
Genetic Lineage:
Genetics trace to Afghani x Skunk lineage known for resin and hardiness. Breeders selected Sirius Black for stability across grows.
-
Seed Type:
Seeds are feminized to ensure predominantly female plants for your grow. That simplifies canopy planning and increases usable bud output.
-
Preferred Climate:
Sirius Black prefers temperate climates with warm summers and mild autumns. Protect plants from early frost in northern areas to secure harvest.
