Alpine Star Feminised

Here is what Alpine Star delivers at harvest: Up to 350g/m² per square metre indoors, Up to 400 gr per plant outdoors in Irish conditions, with resin production peaking at 24% THC. Those numbers tell a story when you work backwards through the 49-63 days indoors, harvest late September outdoors window. The bulk of your final weight accumulates during weeks 5 through 8 — a period where the 65/35 genetics stack calyxes rapidly and trichome coverage shifts from scattered to frosted. Outdoor growers targeting an early-October harvest should count backwards from there, aiming for buds to enter this critical fattening stage through September while there is still usable light and before the wettest weeks arrive.

To reach the upper end of this strain's yield potential (Up to 350g/m² indoors, Up to 400 gr outdoors), focus your efforts on three critical windows during the 49-63 days indoors, harvest late September outdoors period.

Window 1: The first 10 days after flowering begins. Stretch management determines canopy uniformity, which directly impacts light distribution and final yield. Expect modest stretch of 20-30% — a quick defoliation of lower fan leaves at day 7 redirects energy to developing bud sites.

Window 2: Weeks 3-5 of bloom. Myrcene terpene biosynthesis ramps up during this period. Maintain a day/night temperature differential of at least 6-8°C to encourage terpene accumulation. Outdoors in Ireland the sea keeps that swing narrow — a maritime climate has a smaller diurnal range than a continental one, and the midland counties away from the coast are the only places that reliably deliver it. Indoor cultivators should target 25-26°C during lights-on and 18-20°C during lights-off. Supplement with potassium-heavy bloom nutrients at EC 1.6-1.8.

Window 3: Final 10-14 days before harvest. Cease all nutrient input and flush with pH-adjusted water. Monitor trichomes daily with a 60x jeweller's loupe — harvest at 15-20% amber for the full-bodied effect this genetics is known for. Outdoor growers: this window typically falls through the second half of September.

Flowering: 49-63 days indoors, harvest late September outdoors. Indoor yield: Up to 350g/m². Outdoor yield: Up to 400 gr. Plant height: Short. Rated intermediate difficulty.

Irish users report relaxed, sleepy, happy as the defining characteristics, and our experience aligns with that consensus. At 24% THC, this indica sits in a potency bracket where dosage control genuinely matters. A single bowl in a vaporiser at 185°C produces a manageable, pleasant body relaxation with intact mental function — perfect for winding down after a long day in the summer sun. Increasing the dose shifts the experience firmly towards physical sedation, and many users find this their preferred nighttime cultivar during the cooler months. The Myrcene/Humulene terpene combination imparts a flavour that lingers on the palate — earthy and slightly sweet with a fruit-like finish.

Ideal settings: quiet evenings, film nights, post-exercise recovery, and sleep preparation.

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

Alpine Star 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 Irish growing season (September through May) accommodates the 49-63 days indoors, harvest late September outdoors bloom period comfortably for outdoor growers in the warmer, frost-free counties.
