Sister Glue Auto

Read Sister Glue backwards from the harvest: up to 450 g/m2 under lights, up to 500 g/plant outdoors, with resin filling out towards 21% THC. Weight goes on evenly across the 55-65 days of bloom, with a clear surge in the last two weeks that rewards leaving the plant alone. The 47/53 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 55-65 days of bloom decide whether you reach the top of this strain's range (up to 450 g/m2 indoors, up to 500 g/plant 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: 55-65 days. Indoor yield: up to 450 g/m2. Outdoor yield: up to 500 g/plant. Rated intermediate difficulty.

Growers report happy, euphoric as the defining characteristics and our own notes agree. At 21% 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. These three build an aroma that keeps moving through the cure. Fresh off the dry it leads with caryophyllene; after three or four weeks sealed in glass at 16-18°C the humulene underneath comes up and the whole thing gains a layer. Vaporising between 180°C and 195°C catches the widest span of them, since the lighter humulene molecules are the first thing heat destroys.

Sister Glue 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. Autoflowering genetics take the light cycle out of the equation, which suits balcony growers, anyone working around British daylight hours, and anyone who wants the whole thing over quickly. The April to October season accommodates a bloom of 55-65 days comfortably for outdoor growers across the country.
