About M-39 Feminised
The way to plan M-39 is backwards from the day you intend to cut, with 350-450 gr per square metre indoors and 500 gr per plant outdoors as the figures you are working toward, at 16% THC. Count 39-43 days back from that date and you have your flip date. Weight comes on evenly across 39-43 days, with a late surge that punishes impatience. The 60/40 balance gives you stacking density and broad trichome cover together. Outdoors, late March to late April is the sweet spot — after the summer humidity has broken, before the first Highveld frost.
The Aromatic Three
Leading with Caryophyllene, then Myrcene, and Humulene underneath.
Difficulty: easy. In flower for 39-43 days. Stands Short. Indoors it returns 350-450 gr. Outdoors, 500 gr a plant.

M-39 Feminised — Breeder Information
Royal King GeneticsRecreated and stabilised by Royal King Genetics, the breeding team behind this catalogue. Seed lots are germination-tested before they ship. More on the breeding process and about page.
M-39 carries clone-derived parents from the modern hybrid. We backcrossed twice to the dominant parent (BX2) to weld cut-specific traits into seed-stable form. Vigour and finish-time consistency run uniform across the population.
Stabilise the M-39 cross into a seed-uniform line.
Chosen for trichome density, bud structure and the hybrid trait balance the cross was engineered for.
