About Mandarin Feminised
Everything about Mandarin at harvest follows from one decision, which is when you stop. The figures are 150–250 g/m² indoors and 300–500 g/plant outdoors, with resin filling towards 18% THC. The 36/64 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.
Where the weight is won
Three parts of the 8–10 weeks of bloom account for most of the difference between a good result and an average one on a plant rated 150–250 g/m² indoors and 300–500 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. Around a third is usual. A single pass of training across the tallest shoots keeps the top flat.
Weeks three to five. Myrcene 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: 8–10 weeks. Indoor yield: 150–250 g/m². Outdoor yield: 300–500 g/plant. Plant height: 170–210 cm. Rated easy difficulty.
What Mandarin is like in practice
The catalogue lists focused, calm, and that matches what growers here report back. At 18% THC this hybrid sits where the balance is the argument for it. Small doses stay functional, larger ones relax properly, and the 36/64 split means the direction is set by the amount rather than fixed by the plant. The Myrcene and Limonene together leave earth and faint sweetness, with fruit at the end.
Suited to most occasions, with the dose doing the steering.
Terpene breakdown
Primary: Myrcene · Secondary: Limonene · Tertiary: Pinene. 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. Myrcene anchors it, limonene holds the middle, and pinene sits behind both — the last of those being what separates this from other strains leading on the same terpene.
Who it suits
Mandarin 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 8–10 weeks fits inside the season here for outdoor growers, with a tunnel making it comfortable rather than tight.

Mandarin Feminised — Breeder Information
Royal King GeneticsBred and stabilised in-house by Royal King Genetics — our internal breeding team. Every batch is QC'd and germ-tested above 99% before it ships. Read the full breeding process and about page.
Mandarin carries clone-derived parents from the mid-2010s. We backcrossed twice to the dominant parent (BX2) to weld cut-specific traits into seed-stable form. Vigour and cross-derived trait balance run uniform across the population.
Fix parent-cut traits in Mandarin without narrowing the population too far.
Chosen for vigour, terpene saturation and a tight finish window that allows production planning.
