About Querkle Feminised
Read Querkle backwards from the harvest: 450 gr/m² under lights, 500 grams outdoors, with resin filling out towards 22% THC. Most of the final weight lands between weeks five and eight, when the 80/50 genetics stack calyxes quickly and the trichome cover goes from scattered to solid. Outdoors you want that stage falling in late August and early September while the light is still long, so count back to it from the first frost your own area usually sees rather than from a date on a packet.
Getting the weight out of this plant
Three stretches of the 8 weeks of bloom decide whether you reach the top of this strain's range (450 gr/m² indoors, 500 grams 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. Expect 20-30%, which is manageable; stripping the lowest fans around day seven sends the energy up to the sites that will actually finish.
Weeks three to five. Myrcene 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 15-20% amber for the weight of effect this genetics is bought for. Outdoors that lands between late September and mid-October across most of Britain, and the weather forecast should get a vote.
Flowering: 8 weeks. Indoor yield: 450 gr/m². Outdoor yield: 500 grams. Rated intermediate difficulty.
Flavour, aroma and effect
Querkle arrives in stages. The first draw at 22% THC brings a musky earthiness that coats rather than cuts. The focused, relaxed, sleepy character follows within minutes, starting as weight behind the eyes and working down through the shoulders and chest. By about a quarter of an hour it has become a physical stillness — not sedation so much as a strong disinclination to get up. Two to three hours at a moderate dose. The caryophyllene underneath adds a warmth that keeps the whole thing anchored.
Terpene breakdown
Primary: Myrcene · Secondary: Caryophyllene · Tertiary: Linalool. This combination turns up often in cultivars that win things, and it is usually the one growers comment on when a jar is opened for the first time after curing. Myrcene anchors the aroma, caryophyllene occupies the middle, and linalool sits behind both — which is the part that separates this strain from others sharing its primary terpene.
Who it suits
Who does well with Querkle? Indoor growers who want the timeline under their own control. Outdoor growers who want to choose when flowering starts. Anyone with the room and the patience to veg it properly before flipping. Difficulty is rated intermediate, which means a moderate learning curve that rewards attention without demanding a laboratory.
