Alaska Thunderfuck Auto

Everything about Alaska Thunderfuck at harvest follows from one decision, which is when you stop. The figures are 500g/m2 indoors and 850g/plant outdoors, with resin filling towards 22% THC. The 50/50 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 55-65 days of bloom account for most of the difference between a good result and an average one on a plant rated 500g/m2 indoors and 850g/plant 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. Limonene 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: 55-65 days. Indoor yield: 500g/m2. Outdoor yield: 850g/plant. Plant height: Tall. Rated intermediate difficulty.

Alaska Thunderfuck arrives in order. The first draw at 22% THC gives citrus with a bitter edge that lifts off the palate. The energetic, euphoric, happy 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. Caryophyllene underneath contributes warmth that keeps it anchored.

Primary: Limonene · Secondary: Caryophyllene · Tertiary: Linalool. The three shift relative to each other across the cure. Straight off the dry the limonene 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 does well with Alaska Thunderfuck? 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 intermediate, which means a moderate learning curve that rewards attention without needing specialist kit.
