About Corkscrew Auto
The way to plan Corkscrew is backwards from the day you intend to cut, with 455 - 540 g/m2 per square metre indoors and 85 - 170 g/plant per plant outdoors as the figures you are working toward, at 19% THC. Count 55-65 days back from that date and you have your flip date. Weight comes on evenly across 55-65 days, with a late surge that punishes impatience. The 57/43 balance gives you stacking density and broad trichome cover together. Outdoors, late March to late April is the sweet spot — after the summer humidity has broken, before the first Highveld frost.
The Aromatic Three
Leading with Caryophyllene, then Limonene, and Myrcene underneath.
