Black Jack CBD — Sweet Seeds

Seb's take

Seb Silverback

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.

Growing Black Jack CBD: what to expect

Feminized photoperiod stock. You control when she flowers, which is a responsibility as much as a convenience; the light schedule guide keeps you on the right side of it.

She takes a conventional 9 weeks to flower. Conventional is underrated; so is knowing what week you're in.

Expect 400 – 600 g/m² — a working grower's yield, reliable rather than theatrical. The harvest guide will see it in safely.

Listed at 18% THC — potent, verifiably. The figure comes from the breeder's testing, not from our enthusiasm.

Sweetness leads on the nose, and she doesn't whisper it.

The effect chart points firmly at sleep. Schedule accordingly.
