About CBD Blue Shark Feminised
CBD Blue Shark carries linalool as its lead note: lavender with sweetness under it, the smell of a garden border in the evening. Caryophyllene sits beneath it and shows up second, dry and peppery, holding the sweeter notes down. The plant tests at 7% THC across a 49/51 split, though what decides whether any of this reaches the jar is the cure, not the seed.
Growing it for aroma
Growing CBD Blue Shark for terpene expression and growing it for weight are not the same project, and it is worth deciding which one you are on. The Linalool/Caryophyllene/Bisabolol profile does its best work in living soil, where the biology produces compounds a bottle does not contain. Good peat-free compost and worm castings are available in any garden centre here, which makes that approach far less specialist than it sounds.
Stop foliar spraying after the second week of bloom. Anything that lands on a developing trichome is still there at harvest and is tasted rather than seen. In the last three weeks the night temperature decides which terpenes lead: held at 16-18°C the linalool comes forward, while a warmer finish protects the lighter bisabolol notes.
Then the cure, which is where Irish growers lose most of what they built. A ten to fourteen day hang wants 17°C and something near 58% humidity, and the ambient air here will not supply either for most of the year — a closed room and a small dehumidifier will. Into glass afterwards, burped twice daily for a fortnight. The caryophyllene layer arrives somewhere in weeks three and four, not before.
Flowering: 8-9 weeks. Indoor yield: 550 g/m2. Outdoor yield: Up to 450 gr. Plant height: 90-100 cm. Rated medium difficulty.
What CBD Blue Shark is like in practice
The catalogue lists focused, calm, and that matches what growers here report back. At 7% THC this cbd sits where the balance is the argument for it. Small doses stay functional, larger ones relax properly, and the 49/51 split means the direction is set by the amount rather than fixed by the plant. The Linalool and Caryophyllene together leave a finish that keeps shifting across a session.
Suited to most occasions, with the dose doing the steering.
Terpene breakdown
Primary: Linalool · Secondary: Caryophyllene · Tertiary: Bisabolol. This is a combination that turns up repeatedly in cultivars people rate, and it is usually what gets commented on when a jar is opened for the first time after a proper cure. Linalool anchors it, caryophyllene holds the middle, and bisabolol sits behind both — the last of those being what separates this from other strains leading on the same terpene.
Who it suits
CBD Blue Shark suits growers with the fundamentals in place. Understand pH, rough nutrient ratios and a light cycle before committing to it; it asks for competence rather than expertise. Photoperiod genetics leave plant size and harvest date under your control — veg longer for a bigger plant, or flip early when the ceiling is low. A bloom of 8-9 weeks fits inside the season here for outdoor growers, with a tunnel making it comfortable rather than tight.
