Critical 47 Feminised

Everything about Critical 47 at harvest follows from one decision, which is when you stop. The figures are 400g/m² indoors and 500g/plant outdoors, with resin filling towards 20% THC. The 58/42 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 50-60 days of bloom account for most of the difference between a good result and an average one on a plant rated 400g/m² indoors and 500g/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: 50-60 days. Indoor yield: 400g/m². Outdoor yield: 500g/plant. Plant height: Short. Rated easy difficulty.

Critical 47 arrives in order. The first draw at 20% THC gives citrus with a bitter edge that lifts off the palate. The euphoric, creative, calm 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. Temperature decides how much of this profile survives. Low vaporisation at 180-188°C keeps caryophyllene and linalool audible over the limonene; run it hotter, or burn it, and all three collapse into one note that is pleasant enough and tells you nothing.

Who does well with Critical 47? 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 easy, which means a moderate learning curve that rewards attention without needing specialist kit.
