About Critical Plus Feminised

Here is what Critical Plus delivers at harvest: 625 g/m2 per square metre indoors, 1300 g/plant per plant outdoors in New Zealand conditions, with resin production peaking at 23% THC. Those numbers tell a story when you work backwards through the 45-50 days window. Weight distribution across the 45-50 days cycle is pleasingly even, with a noticeable surge in the closing two weeks that rewards growers who resist harvesting prematurely. The 61/39 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 โ€” early enough to dodge late-autumn moisture in most states, late enough to capture the full caryophyllene terpene development.

Maximising Your Harvest

To reach the upper end of this strain's yield potential (625 g/m2 indoors, 1300 g/plant outdoors), focus your efforts on three critical windows during the 45-50 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 6-8ยฐC to encourage terpene accumulation โ€” New Zealand autumn evenings (March-April) naturally provide this swing for outdoor growers. Indoor cultivators should target 25-26ยฐC during lights-on and 18-20ยฐC 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 โ€” harvest at 10-15% amber for a balanced effect. Southern Hemisphere outdoor growers: this window typically falls in late March through mid-April.

Flowering: 45-50 days. Indoor yield: 625 g/m2. Outdoor yield: 1300 g/plant. Rated intermediate difficulty.

What to Expect When Using Critical Plus

New Zealand users report euphoric, focused as the defining characteristics, and our experience aligns with that consensus. At 23% 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 โ€” warm and spiced, drying slightly on the exhale.

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

Terpene Breakdown

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

Suitability and Recommendations

Critical Plus suits growers with fundamental skills already established. You should understand pH management, basic nutrient ratios, and light cycle requirements before committing to this cultivar โ€” 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 โ€” 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 45-50 days bloom period comfortably for outdoor growers in the warmer northern regions. Shipped discreetly within New Zealand with sourced grow figures on every strain page.
