About Neville's Haze Feminised
Everything about Neville's Haze at harvest follows from one decision, which is when you stop. The figures are up to 700 g/m2 indoors and up to 1200 g/plant outdoors, with resin filling towards 21% THC. A 20/80 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 14 weeks of bloom account for most of the difference between a good result and an average one on a plant rated up to 700 g/m2 indoors and up to 1200 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. Terpinolene 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: 14 weeks. Indoor yield: up to 700 g/m2. Outdoor yield: up to 1200 g/plant. Plant height: Tall. Rated medium difficulty.
What Neville's Haze is like in practice
The catalogue lists euphoric, giggly, happy, and that matches what growers here report back. At 21% 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 Terpinolene and Limonene together leave a finish that keeps shifting across a session.
Suited to company, creative work, and getting out of the house.
Terpene breakdown
Primary: Terpinolene · Secondary: Limonene · Tertiary: Ocimene. The three shift relative to each other across the cure. Straight off the dry the terpinolene dominates; three or four weeks sealed in glass at 16-18°C and the ocimene underneath comes up to meet it. Vaporising between 180°C and 195°C catches the widest span, because heat takes the lighter ocimene molecules first.
Who it suits
Neville's Haze 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 14 weeks fits inside the season here for outdoor growers, with a tunnel making it comfortable rather than tight.
