About Sour Kush Auto
The way to plan Sour Kush is backwards from the day you intend to cut, with up to 450 g/m2 per square metre indoors and up to 550 g/plant per plant outdoors as the figures you are working toward, at 26% THC. Count 60-70 days back from that date and you have your flip date. Weight comes on evenly across 60-70 days, with a late surge that punishes impatience. The 50/50 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.
Difficulty: easy. In flower for 60-70 days. Stands Medium. Indoors it returns up to 450 g/m2. Outdoors, up to 550 g/plant a plant.
