Mt. Rainier Feminised

Read Mt. Rainier backwards from the harvest: Up to 400g/m² under lights, Up to 500 gr outdoors, with resin filling out towards 20% THC. Weight goes on evenly across the 8-9 weeks of bloom, with a clear surge in the last two weeks that rewards leaving the plant alone. The 43/57 split gives you calyx density and an even spread of resin rather than one at the cost of the other. Outdoors, late September to mid-October is the window that misses the wettest of the finish across most of the country while still letting the caryophyllene arrive.

Three stretches of the 8-9 weeks of bloom decide whether you reach the top of this strain's range (Up to 400g/m² indoors, Up to 500 gr outdoors). The rest is maintenance.

The first ten days of flower. What the plant does during the stretch sets canopy height, and canopy height sets how evenly the light lands. Somewhere around a third is typical. One pass of low-stress training over the tallest shoots keeps the top flat.

Weeks three to five. Caryophyllene production climbs through here, and it responds to a day-night temperature gap of 6-8°C. British autumn nights hand that to outdoor growers for free from September; indoors you have to build it, at roughly 25-26°C lights-on and 18-20°C lights-off. Bloom feed goes potassium-heavy around EC 1.6-1.8.

The last ten to fourteen days. Stop feeding and run pH-corrected water. Check trichomes daily under a 60x loupe — cut at 10-15% amber for the middle of the range. Outdoors that lands between late September and mid-October across most of Britain, and the weather forecast should get a vote.

Flowering: 8-9 weeks. Indoor yield: Up to 400g/m². Outdoor yield: Up to 500 gr. Rated intermediate difficulty.

Growers report relaxed, happy, euphoric as the defining characteristics and our own notes agree. At 20% THC this hybrid sits where the balance is the selling point. Taken small it stays functional; taken larger it relaxes properly. The ${indica}/${sativa} split means the direction is set by how much you take rather than fixed by the genetics. The Caryophyllene/Myrcene pairing leaves warmth and spice that dries slightly on the exhale.

Best suited to most occasions — the dose does the steering.

Primary: Caryophyllene · Secondary: Myrcene · Tertiary: Humulene. How this profile survives the journey from flower to vapour depends on temperature. Low vaporisation, 180-188°C, keeps the myrcene and humulene audible over the caryophyllene base. Run it hotter, or burn it, and the three collapse into one note — pleasant enough, but none of the complexity that made it worth choosing.

Mt. Rainier suits growers with the basics in place. Understand pH, rough nutrient ratios and light cycles before you commit to it; it asks for competence rather than expertise. Photoperiod genetics leave plant size and harvest date under your control — veg longer for bigger plants, or flip early when space is short. The April to October season accommodates a bloom of 8-9 weeks comfortably for outdoor growers across the country.
