Sister Glue Auto

Here is what Sister Glue delivers at harvest: up to 450 g/m2 per square metre indoors, up to 500 g/plant per plant outdoors in UK conditions, with resin production peaking at 21% THC. Those numbers tell a story when you work backwards through the 55-65 days window. Weight distribution across the 55-65 days cycle is pleasingly even, with a noticeable surge in the closing two weeks that rewards growers who resist harvesting prematurely. The 47/53 balance means you get both calyx stacking density and respectable trichome spread. For outdoor UK customers, the ideal harvest window lands between late September and mid-October — early enough to dodge the wet autumn finish in most regions, late enough to capture the full caryophyllene terpene development.

To reach the upper end of this strain's yield potential (up to 450 g/m2 indoors, up to 500 g/plant outdoors), focus your efforts on three critical windows during the 55-65 days period.

Window 1: The first 10 days after flowering begins. Stretch management determines canopy uniformity, which directly impacts light distribution and final yield. Moderate 30-40% stretch is typical. One round of low-stress training on the tallest shoots keeps everything level.

Window 2: Weeks 3-5 of bloom. Caryophyllene terpene biosynthesis ramps up during this period. Maintain a day/night temperature differential of at least 6-8°C to encourage terpene accumulation — UK autumn evenings (September-October) naturally provide this swing for outdoor growers. 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 10-15% amber for a balanced effect. UK outdoor growers: this window typically falls from late September through mid-October.

Flowering: 55-65 days. Indoor yield: up to 450 g/m2. Outdoor yield: up to 500 g/plant. Rated intermediate difficulty.

UK customers report happy, euphoric as the defining characteristics, and our experience aligns with that consensus. At 21% THC, this hybrid sits in a potency bracket where versatility is the main advantage. Morning users report functional clarity at lower doses. Evening users report satisfying relaxation at higher doses. The ${indica}/${sativa} balance means the dominant effect direction shifts with consumption amount rather than being locked into a single character. The Caryophyllene/Myrcene terpene combination imparts a flavour that lingers on the palate — warm and spiced, drying slightly on the exhale.

Ideal settings: adaptable across occasions — adjust dose to match the energy level your situation calls for.

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

Sister Glue 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. Autoflowering genetics eliminate the need for light cycle manipulation, making this ideal for UK balcony growers, guerrilla setups, and anyone wanting a fast turnaround from seed to harvest. The UK growing season (April through October) accommodates the 55-65 days bloom period comfortably for outdoor cultivators across the country.
