Seb's take
Black Jack CBD comes from crossing the top-shelf Black Jack with a clone chosen purely for its CBD content, and the earthy, incense-and-lemon flavour shows the care taken. The effect is long-lasting and feel-good rather than sedating outright, though sleepiness and appetite both tend to follow. Not the easiest plant for a beginner, but a productive one for the patient.
Where it comes from
Black Jack CBD came about, as the record tells it, by crossing Sweet Seeds' top-shelf Black Jack with a clone chosen purely for its CBD content, CBD Diesel in the lineage. The result is a balanced fifty-fifty plant that holds THC and CBD in near-equal measure, the record putting each in a broad band. It is a deliberate piece of breeding rather than a happy accident, and the care taken shows in the finish.
Nose & flavour
Sweet on first acquaintance, with incense and a clean lemon note giving the nose its character, and an earthy, flowery depth beneath. It is an intense aroma for a balanced plant, the sort that fills a room without apology and lingers a while after.
The high
The effect is long-lasting and even-tempered, feel-good rather than flattening, though sleepiness and a sharpened appetite both tend to follow in their own time. One for the later hours, when there is nothing further required of you and the evening is yours to spend.
Growing it
Flowering runs 56 to 63 days, and she is, by the record's own admission, not the gentlest plant for a first-timer. She asks for a steady hand. Reward the patience, though, and she is among the more productive of her kind: up to 600 g/m² indoors, and as much as 650 grams per plant outdoors, gathered mostly in early autumn. A solid structure holds it all up, at some 10 to 18 per cent THC with CBD to match.
