About Super Lemon Haze Feminised

Everything about Super Lemon Haze at harvest follows from one decision, which is when you stop. The figures are up to 800 gr/m2 indoors and up to 1200 gr/plant outdoors, with resin filling towards 25% THC. A 14/86 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 10 weeks of bloom account for most of the difference between a good result and an average one on a plant rated up to 800 gr/m2 indoors and up to 1200 gr/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: 10 weeks. Indoor yield: up to 800 gr/m2. Outdoor yield: up to 1200 gr/plant. Plant height: Tall. Rated medium difficulty.

What Super Lemon Haze is like in practice

The catalogue lists happy, energetic, creative, and that matches what growers here report back. At 25% 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. 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. Terpinolene anchors it, limonene holds the middle, and ocimene sits behind both — the last of those being what separates this from other strains leading on the same terpene.

Who it suits

Super Lemon 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 10 weeks fits inside the season here for outdoor growers, with a tunnel making it comfortable rather than tight.
