About Critical Glue Auto

South Africa is really two growing countries, and Critical Glue does not behave the same way in both. North and east of the escarpment the rain arrives in summer, so this 89/11 indica does its flowering while the air is still heavy; in the Western Cape the rain comes in winter, so the same plant ripens through a dry autumn instead. Dense indica flowers at 22% THC are the wrong shape for a wet summer finish. Between Durban and Richards Bay, once humidity sits above 65% for days at a stretch, botrytis reaches the core of a cola before anything shows on the surface β€” defoliate early, space plants wider than feels necessary, and keep air moving under the canopy. That same density turns into an advantage on the Highveld: above 1 400 m the autumn nights go cold and dry, myrcene sharpens as the temperature drops, and a compact frame shrugs off a Free State storm that would flatten something taller.

The Aromatic Three

Leading with Myrcene, then Caryophyllene, and Linalool underneath.

Difficulty: easy. In flower for 7–9 weeks from seed. Stands 70–110 cm. Indoors it returns 325–425 g/mΒ². Outdoors, 400–500 g/plant a plant.

Royal King Genetics Auto Line β€” recessive trait stabilisation
Stabilisation Notes β€” What This Means for Your Grow

Critical Glue is an autoflowering line that has been progressed through five rounds of Royal King Genetics autoflower stabilisation. The autoflower trait is recessive β€” fixing it takes multi-generation work β€” and at F5 the auto trigger and finish window are welded across the pack.

Breeding Goal

Stabilise the recessive ruderalis trait in Critical Glue for uniform auto-trigger.

Selection Focus

Chosen for trichome coverage, stout structure and consistent flowering time across the pack.
