Germination rate: 97.4% (n=250)
Last QC test date: 2026-04-23
Indoor yield: 375-510 g/mยฒ (avg across 13 verified grower reports)
Outdoor yield: 365-610 g/plant (avg across 8 verified grower reports)

About CBD Critical Mass Feminised

Germination & Early Veg (Days 1-14): CBD Critical Mass seeds typically crack within 48 hours using the damp paper towel method and break soil by around day 3. Early growth was steady and symmetrical โ€” neither racing ahead nor lagging behind. Four well-developed nodes by day 14 with balanced internodal distance that hinted at the hybrid structure to come. Damping off is uncommon at around 70% relative humidity during this phase.

Vegetative Growth (Weeks 3-6): Responded beautifully to a simple top-and-train approach. Topping at node 4 produced six strong lateral leaders that we tied down gently, resulting in an even canopy across a 70cm x 70cm area by the time we flipped.

Flower (Weeks 1-8): This is where the 41/59 genetics of CBD Critical Mass truly revealed itself. The myrcene aroma appeared in week 3 of flower and intensified steadily. Trichome coverage became visually striking from week 5 onward. Final indoor yield: 500 g/m2. THC testing at 7%. Difficulty rating: intermediate.

Continuing the Grow Diary

Mid-Flower (Weeks 4-6): The transformation accelerated dramatically. Bud sites that were wispy clusters at week 3 swelled into properly defined colas. Balanced development across all bud sites. The canopy we established during veg paid dividends now โ€” eight equally developed colas rather than one dominant top and a collection of lesser branches. Trichome production was visible to the naked eye from week 4 onward.

Late Flower and Ripening (Weeks 6-8): Nutrient input dropped to plain water with a splash of molasses for the final 10 days. The myrcene aroma became powerful enough that carbon filtration was essential โ€” our neighbours would have noticed otherwise. Trichomes progressed from clear to milky across the final fortnight, with amber heads appearing on sugar leaves first. A common harvest window is around 15% amber on the calyxes.

Dry and Cure (Post-Harvest): Whole-plant hang dry in a darkened room at 17ยฐC and 58% humidity for 12 days. Stems snapped cleanly rather than bending, confirming the moisture content was appropriate for jarring. After 4 weeks of glass jar curing with twice-daily burping (first 2 weeks) then daily burping (weeks 3-4), the bouquet fully developed. Final weight confirmed the 500 g/m2 yield estimate. The linalool secondary terpene became far more pronounced after curing than it was at harvest โ€” a reminder that the drying and curing process genuinely creates flavour rather than merely preserving it.

Flowering: 8 weeks. Indoor yield: 500 g/m2. Rated intermediate difficulty. Feminised seeds.

What to Expect When Using CBD Critical Mass

New Zealand users report relaxed, calm, focused as the defining characteristics, and our experience aligns with that consensus. At 7% THC, this cbd 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 Myrcene/Linalool terpene combination imparts a flavour that lingers on the palate โ€” earthy and slightly sweet with a fruit-like finish.

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

Terpene Breakdown

Primary: Myrcene ยท Secondary: Linalool ยท Tertiary: Pinene. Flavour translation from flower to vapour and smoke differs with this terpene combination. Low-temperature vaporisation (180-188ยฐC) highlights the linalool and pinene notes whilst keeping myrcene 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

CBD Critical Mass 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 8 weeks bloom period comfortably for outdoor growers in the warmer northern regions. Shipped discreetly within New Zealand with sourced grow figures on every strain page.
