About Blue Princess Feminized
Germination & Early Veg (Days 1-14): Blue Princess 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 1-9): This is where the 5/95 genetics of Blue Princess truly revealed itself. The terpinolene aroma appeared in week 3 of flower and intensified steadily. Trichome coverage became visually striking from week 5 onward. THC testing at 18%. 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 7-9): Nutrient input dropped to plain water with a splash of molasses for the final 10 days. The terpinolene 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 limonene 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.
Rated intermediate difficulty. Feminised seeds.
What to Expect When Using Blue Princess
UK customers report happy, energetic, creative as the defining characteristics, and our experience aligns with that consensus. At 18% 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 Terpinolene/Limonene terpene combination imparts a flavour that lingers on the palate — complex and shifting, revealing new notes across the session.
Ideal settings: creative pursuits, social gatherings, outdoor adventures, and daytime leisure.
Terpene Breakdown
Primary: Terpinolene · Secondary: Limonene · Tertiary: Ocimene. Together these three compounds construct an aromatic signature that evolves throughout the curing process. Freshly dried flower leads with terpinolene presence, but after three to four weeks in sealed glass jars at 16-18°C, the ocimene undertone strengthens and the overall bouquet develops a layered complexity. Vaporisation between 180°C and 195°C captures the broadest spectrum of these terpenes — higher temperatures degrade the more volatile ocimene molecules first.
Suitability and Recommendations
Blue Princess 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 bloom period comfortably for outdoor cultivators across the country. Shipped discreetly across the UK with our germination guarantee.
