Treasure Island Feminised

Everything about Treasure Island at harvest follows from one decision, which is when you stop. The figures are 340-454 g/m2 indoors and 454-709 g/plan outdoors, with resin filling towards 25% THC. The 40/60 balance gives steady gain with a lift in the closing fortnight. Outdoors, aim to be finished by mid-October rather than hoping for a dry third week of it.

Three parts of the 8-9 weeks of bloom account for most of the difference between a good result and an average one on a plant rated 340-454 g/m2 indoors and 454-709 g/plan outdoors.

The stretch, days 1-10 after the flip. Canopy height set here decides how evenly light lands for the rest of the run. Around a third is usual. A single pass of training across the tallest shoots keeps the top flat.

Weeks three to five. Caryophyllene production climbs through this stretch and responds to a 6-8°C gap between lights-on and lights-off. Outdoors an Irish September provides that without help; indoors it has to be built, at roughly 25°C by day and 18-20°C at night. Bloom feed goes potassium-forward around EC 1.6-1.8.

The final fortnight. Feeding stops, plain pH-corrected water goes on, and the loupe comes out daily. Ten to fifteen per cent amber sits in the middle of its range. Outdoors, that falls between late September and mid-October, and the forecast gets a say.

Flowering: 8-9 weeks. Indoor yield: 340-454 g/m2. Outdoor yield: 454-709 g/plan. Plant height: Medium (150-245 cm). Rated moderate difficulty.

Treasure Island arrives in order. The first draw at 25% THC gives peppercorn heat that lands at the back of the throat. The relaxed, happy, euphoric character follows in minutes, as head and body together. Thinking stays clear while the muscles let go by degrees, which is what makes the dose, rather than the genetics, the thing that decides the evening. Limonene underneath contributes a lift that stops it going heavy.

Primary: Caryophyllene · Secondary: Limonene · Tertiary: Myrcene. 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. Caryophyllene anchors it, limonene holds the middle, and myrcene sits behind both — the last of those being what separates this from other strains leading on the same terpene.

Who does well with Treasure Island? Indoor growers who want to choose their own timeline. Tunnel growers who want to decide when flowering starts rather than letting August decide it. Anyone with the space to veg it properly first. Rated moderate, which means a moderate learning curve that rewards attention without needing specialist kit.
