M-39 Feminised

Here is what M-39 delivers at harvest: 350-450 gr per square metre indoors, 500 gr per plant outdoors in New Zealand conditions, with resin production peaking at 16% THC. Those numbers tell a story when you work backwards through the 39-43 days window. Weight distribution across the 39-43 days cycle is pleasingly even, with a noticeable surge in the closing two weeks that rewards growers who resist harvesting prematurely. The 60/40 balance means you get both calyx stacking density and respectable trichome spread. For outdoor growers, the ideal harvest window lands between mid-March and mid-April — early enough to dodge late-autumn moisture in most states, late enough to capture the full caryophyllene terpene development.

To reach the upper end of this strain's yield potential (350-450 gr indoors, 500 gr outdoors), focus your efforts on three critical windows during the 39-43 days period.

Window 1: The first 10 days after flowering begins. Stretch management determines canopy uniformity, which directly impacts light distribution and final yield. Moderate 30-40% stretch is typical. One round of low-stress training on the tallest shoots keeps everything level.

Window 2: Weeks 3-5 of bloom. Caryophyllene terpene biosynthesis ramps up during this period. Maintain a day/night temperature differential of at least 6-8°C to encourage terpene accumulation — New Zealand autumn evenings (March-April) naturally provide this swing for outdoor growers. Indoor cultivators should target 25-26°C during lights-on and 18-20°C during lights-off. Supplement with potassium-heavy bloom nutrients at EC 1.6-1.8.

Window 3: Final 10-14 days before harvest. Cease all nutrient input and flush with pH-adjusted water. Monitor trichomes daily with a 60x jeweller's loupe — harvest at 10-15% amber for a balanced effect. Southern Hemisphere outdoor growers: this window typically falls in late March through mid-April.

Flowering: 39-43 days. Indoor yield: 350-450 gr. Outdoor yield: 500 gr. Rated intermediate difficulty.

New Zealand users report creative, happy, talkative as the defining characteristics, and our experience aligns with that consensus. At 16% THC, this hybrid sits in a potency bracket where versatility is the main advantage. Morning users report functional clarity at lower doses. Evening users report satisfying relaxation at higher doses. The ${indica}/${sativa} balance means the dominant effect direction shifts with consumption amount rather than being locked into a single character. The Caryophyllene/Myrcene terpene combination imparts a flavour that lingers on the palate — warm and spiced, drying slightly on the exhale.

Ideal settings: adaptable across occasions — adjust dose to match the energy level your situation calls for.

Primary: Caryophyllene · Secondary: Myrcene · Tertiary: Humulene. Flavour translation from flower to vapour and smoke differs with this terpene combination. Low-temperature vaporisation (180-188°C) highlights the myrcene and humulene notes whilst keeping caryophyllene as a foundation. Higher temperatures or combustion flatten the profile into a single-note experience — still pleasant, but lacking the complexity that makes this cultivar genuinely interesting to those who appreciate flavour.

M-39 suits growers with fundamental skills already established. You should understand pH management, basic nutrient ratios, and light cycle requirements before committing to this cultivar — it will not hold your hand, but it will not punish minor mistakes harshly either. Photoperiod genetics give you complete control over plant size and harvest timing — extend the vegetative phase for larger plants or flip early for a quicker turnaround in compact spaces. The New Zealand growing season (October through April) accommodates the 39-43 days bloom period comfortably for outdoor growers in the warmer northern regions.
