Seb's take
Black Diamond CBD draws on Blackberry, Diamond OG, and CBD-5 lines for a rich berry nose with a toasted, nutty edge and an earthy finish. THC stays negligible while the CBD does the work, calm, anti-inflammatory, and gently euphoric enough for either end of the day. A strain built for relief, not for a story afterwards.
Where it comes from
A CBD line with genuine pedigree — the record traces it through Blackberry, Diamond OG, and CBD 5, stabilised across a Cross CBD 5 by CBD 5 pairing. Kera Seeds hold the THC to a whisper and push the CBD to fifteen or even twenty per cent, tilting the plant sixty per cent sativa in the bargain. A considered cross, built around a single cannabinoid and bred to hold it steady from one seed to the next.
Nose & flavour
A rich berry nose leads, courtesy of the Blackberry side, with a toasted, nutty warmth behind it and a dank, earthy base underneath. The smoke runs smooth, and the terpene profile is fuller than most CBD lines manage — this is not the flavourless proposition such strains can be. Robust and characterful, jar to exhale.
The high
With THC held to a tenth or two of a per cent, there is no real intoxication here — the CBD does the work, and at fifteen to twenty per cent there is plenty of it. The result is calm and gently euphoric, settling without sedating, and clear enough for either end of the day. A rounded, motivating ease that leaves you entirely yourself. Built for the effect, not the story afterwards.
Growing it
Give her the headroom — she reaches three metres given the room, so this is one for a tall tent or the open air. Flowering runs fifty-five to sixty days for a solid 500 g/m². The sixty per cent sativa lean brings vigour and stretch, so train and support early where the ceiling is low. A generous, straightforward grow, provided you can house the height she is inclined to reach for.
