About Ecto Cooler Feminised
South Africa is really two growing countries, and Ecto Cooler does not behave the same way in both. North and east of the escarpment the rain arrives in summer, so this 77/23 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 18% 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, linalool 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 Linalool, then Myrcene, and Caryophyllene underneath.
