About CBD Blue Shark Feminised
Cured properly and opened cold, CBD Blue Shark leads with linalool: lavender softened by sweetness, the way a border bed smells after rain. Underneath it caryophyllene adds a dry peppery floor, and it reads mid-palate rather than on the first pass. This 49/51 cbd tests at 7% THC, but potency is the least interesting number here: what separates CBD Blue Shark from the others on the same shelf is how the aroma behaves across a cure, and that is a question of storage and patience rather than genetics alone.
Growing it for the nose rather than the scales
Chasing terpene expression in CBD Blue Shark pulls against chasing yield, and it is worth knowing which one you are doing before you start. The Linalool/Caryophyllene/Bisabolol profile does its best work in living soil, where the microbial side produces secondary compounds a bottle cannot. That is easier here than it sounds: decent peat-free compost and worm castings are a garden centre purchase in most British towns.
Through the 8-9 weeks of bloom, stop foliar spraying after week two — anything landing on developing trichomes is still there at harvest and you will taste it. The final three weeks decide which terpenes dominate the cured flower: nights held at 16-18°C push linalool forward, while a warmer finish protects the lighter bisabolol notes at the top.
The cure is where most of the flavour is lost in this country, and the reason is the weather. A 10-14 day hang wants 15-18°C at 55-60% relative humidity, which a British autumn will not give you in a spare room — a temperature-controlled cupboard or a wine fridge set to 16°C solves it for the price of one wasted harvest. Then into glass, burped twice a day for the first fortnight. The caryophyllene layer that makes this one worth growing does not appear until somewhere between weeks three and four in the jar.
Flowering: 8-9 weeks. Indoor yield: 550 g/m2. Outdoor yield: Up to 450 gr. Plant height: 90-100 cm. Rated intermediate difficulty.
What CBD Blue Shark is actually like
Growers report focused, calm as the defining characteristics and our own notes agree. At 7% THC this cbd sits where the balance is the selling point. Taken small it stays functional; taken larger it relaxes properly. The ${indica}/${sativa} split means the direction is set by how much you take rather than fixed by the genetics. The Linalool/Caryophyllene pairing leaves a finish that keeps changing across a session.
Best suited to most occasions — the dose does the steering.
Terpene breakdown
Primary: Linalool · Secondary: Caryophyllene · Tertiary: Bisabolol. This combination turns up often in cultivars that win things, and it is usually the one growers comment on when a jar is opened for the first time after curing. Linalool anchors the aroma, caryophyllene occupies the middle, and bisabolol sits behind both — which is the part that separates this strain from others sharing its primary terpene.
Who it suits
CBD Blue Shark suits growers with the basics in place. Understand pH, rough nutrient ratios and light cycles before you commit to it; it asks for competence rather than expertise. Photoperiod genetics leave plant size and harvest date under your control — veg longer for bigger plants, or flip early when space is short. The April to October season accommodates a bloom of 8-9 weeks comfortably for outdoor growers across the country.
