About Coffee Feminised
Everything about Coffee at harvest follows from one decision, which is when you stop. The figures are 250–500 g/m² indoors and 400–600 g/plant outdoors, with resin filling towards 24% THC. A 12/88 plant lays its weight down gradually instead of in a rush, so there is no single fattening window to aim at. The temptation in an Irish September is to cut early because the forecast looks poor; that costs more than the weather would have.
Where the weight is won
Three parts of the 7–9 weeks of bloom account for most of the difference between a good result and an average one on a plant rated 250–500 g/m² indoors and 400–600 g/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. Half again on top of veg height is normal. Supercrop anything that breaks the line inside the first week, or you spend the remaining weeks lighting one branch properly.
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. Five to ten per cent amber keeps the clarity intact. Outdoors, that falls between late September and mid-October, and the forecast gets a say.
Flowering: 7–9 weeks. Indoor yield: 250–500 g/m². Outdoor yield: 400–600 g/plant. Plant height: 100–140 cm. Rated easy difficulty.
What Coffee is like in practice
The catalogue lists relaxed, creative, focused, and that matches what growers here report back. At 24% THC this sativa sits where there is a usable window rather than a cliff. At 175-185°C the first effect is lift and mental energy, which suits company, a long walk, or work that benefits from it. The body stays light, so it is a genuine daytime option for anyone with a tolerance. The Limonene and Terpinolene together leave a clean citrus finish that clears quickly.
Suited to company, creative work, and getting out of the house.
Terpene breakdown
Primary: Limonene · Secondary: Terpinolene · Tertiary: Pinene. Temperature decides how much of this profile survives. Low vaporisation at 180-188°C keeps terpinolene and pinene 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 it suits
Coffee suits growers with the fundamentals in place. Understand pH, rough nutrient ratios and a light cycle before committing to it; it asks for competence rather than expertise. Photoperiod genetics leave plant size and harvest date under your control — veg longer for a bigger plant, or flip early when the ceiling is low. A bloom of 7–9 weeks fits inside the season here for outdoor growers, with a tunnel making it comfortable rather than tight.
