About U2 Kush Auto

U2 Kush carries myrcene as its lead note: damp earth and something sweet gone slightly over, the smell of a hedgerow in late August. Caryophyllene sits beneath it and shows up second, dry and peppery, holding the sweeter notes down. The plant tests at 24% THC across a 88/12 split, though what decides whether any of this reaches the jar is the cure, not the seed.

Growing it for aroma

Growing U2 Kush for terpene expression and growing it for weight are not the same project, and it is worth deciding which one you are on. The Myrcene/Caryophyllene/Linalool 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 myrcene comes forward, while a warmer finish protects the lighter linalool 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: 50-60 days. Indoor yield: up to 300 g/m2. Outdoor yield: up to 350 g/plant. Plant height: 90-120 cm. Medium. Rated easy difficulty.

Flavour, aroma and effect

U2 Kush arrives in order. The first draw at 24% THC gives earth and musk, coating rather than sharp. The creative, uplifted, calm character follows in minutes, as weight behind the eyes that works down through the shoulders. By a quarter of an hour it reads as physical stillness rather than sedation — a strong disinclination to stand up. Two to three hours at a sensible dose. Caryophyllene underneath contributes warmth that keeps it anchored.

Terpene breakdown

Primary: Myrcene · Secondary: Caryophyllene · Tertiary: Linalool. The three shift relative to each other across the cure. Straight off the dry the myrcene dominates; three or four weeks sealed in glass at 16-18°C and the linalool underneath comes up to meet it. Vaporising between 180°C and 195°C catches the widest span, because heat takes the lighter linalool molecules first.

Who it suits

Who does well with U2 Kush? Back-garden and balcony growers in Dublin, Cork and Galway. Anyone who wants a crop dry and put away before the autumn closes in. Indoor growers short of headroom. The autoflowering genetics run to their own clock, so there is no schedule to manage and no anxiety about light leaks. Rated easy, which means a moderate learning curve that rewards attention without needing specialist kit.

Autoflower Stabilisation (F5) — ruderalis trait fixing
Stabilisation Notes — What This Means for Your Grow

U2 Kush is our F5 autoflower line. Five rounds of selection have fixed both the autoflower trigger and the indica relaxation profile the cultivar is known for. The recessive ruderalis trait demands this depth of work to express uniformly.

Breeding Goal

Reach auto trigger and finish-window uniformity for the U2 Kush pack.

Selection Focus

Chosen for resin output, a low-slung stature and a clean indica terpene fingerprint.

Pollen / Mother Source

Royal King Genetics select-mother programme — pollen drawn from an internally maintained reversed-female line.
