About Cinderella 99 Feminized
Germination & Early Veg (Days 1-14): Cinderella 99 seeds typically crack within 48 hours using the damp paper towel method and break soil by around day 3. Early growth was rapid and upright — narrow first leaves reaching eagerly towards the light from day one. By the end of week two, five nodes were visible with noticeable spacing between each, signalling the sativa-dominant growth pattern ahead. Damping off is uncommon at around 70% relative humidity during this phase.
Vegetative Growth (Weeks 3-6): Vertical growth demanded attention. Even with low-stress training started in week 3, this plant wanted to climb. We bent the main stem at a 90-degree angle in week 4 and the secondary branches quickly caught up, creating a naturally flat canopy by week 6.
Flower (Weeks 1-63): This is where the 5/95 genetics of Cinderella 99 truly revealed itself. The limonene aroma appeared in week 3 of flower and intensified steadily. Trichome coverage became visually striking from week 5 onward. Plant height: ~48 inches (122 cm) finished when flipped at 18 inches. THC testing at 22%. 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. The elongated bud structure continued developing lengthwise, with fresh calyxes stacking along the main stems. Interestingly, the secondary branches produced proportionally larger buds than expected — the open structure allowed light to reach lower sites that a bushier plant would have shaded out entirely.
Late Flower and Ripening (Weeks 61-63): Nutrient input dropped to plain water with a splash of molasses for the final 10 days. The limonene aroma became powerful enough that carbon filtration was essential — 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 17°C 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. The terpinolene secondary terpene became far more pronounced after curing than it was at harvest — a reminder that the drying and curing process genuinely creates flavour rather than merely preserving it.
Flowering: 56-63 days. Plant height: ~48 inches (122 cm) finished when flipped at 18 inches. Rated intermediate difficulty. Feminised seeds.
What to Expect When Using Cinderella 99
UK customers report euphoric, sleepy, energetic as the defining characteristics, and our experience aligns with that consensus. At 22% THC, this sativa sits in a potency bracket where most users find a productive sweet spot. Vaporised at 175-185°C, the initial effect is a noticeable uplift in mood and mental energy that pairs well with creative projects, long walks, or an afternoon with friends. The body remains light and mobile throughout, making this a genuine daytime option for those with THC tolerance. The Limonene/Terpinolene terpene combination imparts a flavour that lingers on the palate — zesty and bright with a clean, refreshing aftertaste.
Ideal settings: creative pursuits, social gatherings, outdoor adventures, and daytime leisure.
Terpene Breakdown
Primary: Limonene · Secondary: Terpinolene · Tertiary: Pinene. Flavour translation from flower to vapour and smoke differs with this terpene combination. Low-temperature vaporisation (180-188°C) highlights the terpinolene and pinene notes whilst keeping limonene 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.
Suitability and Recommendations
Cinderella 99 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 UK growing season (April through October) accommodates the 56-63 days bloom period comfortably for outdoor cultivators across the country.
