About Highwayman Feminized

Germination & Early Veg (Days 1-14): Highwayman seeds typically crack within 48 hours using the damp paper towel method and break soil by around day 3. Early growth was squat and vigorous β€” broad cotyledons followed by wide, dark-green fan leaves typical of the indica heritage. By day 14 expect around four established nodes with tight internodal spacing. Damping off is uncommon at around 70% relative humidity during this phase.

Vegetative Growth (Weeks 3-6): Lateral branching exploded after topping at the fourth node. The plant filled a 60cm x 60cm footprint by week 5, staying under 40cm tall β€” ideal for UK growers working in compact tent setups.

Flower (Weeks 1-70): This is where the 73/27 genetics of Highwayman truly revealed itself. The caryophyllene aroma appeared in week 3 of flower and intensified steadily. Trichome coverage became visually striking from week 5 onward. Final indoor yield: ~12 oz/plant. THC testing at 21%. 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. Density increased almost daily β€” squeezing a developing bud at week 5 felt like pressing a firm rubber ball. Fan leaf removal at the start of week 4 improved airflow through the lower canopy, critical since our grow room humidity hovered around 55% through this British autumn.

Late Flower and Ripening (Weeks 68-70): Nutrient input dropped to plain water with a splash of molasses for the final 10 days. The caryophyllene aroma became powerful enough that carbon filtration was essential β€” 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 17Β°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. Final weight confirmed the ~12 oz/plant yield estimate. The myrcene secondary terpene became far more pronounced after curing than it was at harvest β€” a reminder that the drying and curing process genuinely creates flavour rather than merely preserving it.

Flowering: 56-70 days. Indoor yield: ~12 oz/plant. Rated intermediate difficulty. Feminised seeds.

Flavour, Aroma, and Experience

The sensory arc of Highwayman unfolds in stages. Initial inhalation at 21% THC brings a warm peppery spice that tingles at the back of the throat. The euphoric, creative, calm effects emerge within minutes, beginning as a pleasant heaviness behind the eyes that migrates downward through the shoulders, chest, and limbs. By the fifteen-minute mark, a deep physical stillness sets in β€” not sedation exactly, but a reluctance to move that makes the couch remarkably appealing. Duration runs 2-3 hours at moderate doses. The myrcene secondary terpene adds a distinct layer: additional body depth that reinforces the physical dimension.

Terpene Breakdown

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

Suitability and Recommendations

Who grows Highwayman 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.
