Black Jack CBD is Seed City Bulk Cannabis Seeds’ CBD-rich take on the Black Jack line, available as feminised seeds. It keeps the strain balanced in more ways than one: the genetics are Black Jack x selected CBD-rich clone with Diesel ancestry, and the plant is listed as 50% indica and 50% sativa.
The cannabinoid profile is the main reason to look at this one. THC is given at 10–18%, with CBD at 9–17%, so it’s aimed at shoppers who want a smoother, more even Black Jack-style option rather than a straight high-THC version. The reported effect is relaxed and smooth, matching that near-balanced THC and CBD range.
In the grow room, Black Jack CBD is a photoperiod strain with an indoor flowering time of 8–9 weeks. Outdoors, harvest is expected in late September. It’s suitable for both indoor and outdoor cultivation, forming a strong central cola with side branches that carry multiple buds. Expected yields are 400–600 g/m² indoors and 375–650 g per plant outdoors.
The aroma mixes sweetness, incense and lemon with a fresh edge. On the palate it stays in a sweet citrus and lemon line, so it should appeal if you like cleaner, brighter flavours without losing that deeper incense note.
