About Deadly Sativas Mixpack

Germination & Early Veg (Days 1-14): Deadly Sativas Mixpack 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 15/85 genetics of Deadly Sativas Mixpack truly revealed itself. The limonene aroma appeared in week 3 of flower and intensified steadily. Trichome coverage became visually striking from week 5 onward. THC testing at 22%. Difficulty rating: intermediate.

What's Inside the Deadly Sativas Mixpack

The Deadly Sativas Mixpack is an assortment of three separate strains rather than a single cultivar, and every pack splits evenly between them. The 3x5=15 option is 5 seeds of each strain, 3x10=30 is 10 of each, 3x15=45 is 15 of each, and 3x20=60 is 20 of each.

  • Alice In Wonderland — a potent sativa known for clear-headed, creative stimulation.
  • Amnesia Haze — a Dutch classic with citrus, incense and sweet spice terpenes. The autoflowering version finishes faster.
  • Panama Red — a pure landrace sativa from the Panamanian highlands, one of the defining varieties of 1960s–70s counterculture.
The specifications listed elsewhere on this page describe the pack as a whole; each strain has its own flowering time, structure and terpene profile.

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 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 pinene 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.

Flavour, Aroma, and Experience

The sensory arc of Deadly Sativas Mixpack unfolds in stages. Initial inhalation at 22% THC brings a bright, almost sparkling citrus note that lifts the palate. The energizing, creative, euphoric, uplifted effects emerge within minutes, arriving as a noticeable sharpening of sensory perception. Colours look more saturated, music sounds richer, and conversations take interesting tangential paths. This cerebral engagement sustains for 2-3 hours with a gentle plateau rather than a sudden peak and crash. The pinene secondary terpene adds a distinct layer: a mental alertness that keeps cognition crisp.

Terpene Breakdown

Primary: Limonene · Secondary: Pinene · Tertiary: Terpinolene. Together these three compounds construct an aromatic signature that evolves throughout the curing process. Freshly dried flower leads with limonene presence, but after three to four weeks in sealed glass jars at 16-18°C, the terpinolene 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 terpinolene molecules first.

Suitability and Recommendations

Who grows Deadly Sativas Mixpack successfully? Indoor growers seeking full control over their harvest timeline. Outdoor cultivators who want to decide exactly when flowering begins. Anyone with the space and patience to vegetate this plant to its full potential before triggering bloom. Difficulty is rated intermediate, meaning a moderate learning curve that rewards attention without demanding laboratory-grade conditions. Delivered UK-wide in discreet, unbranded packaging with germination guarantee included.
