About White Widow Feminised
The way to plan White Widow is backwards from the day you intend to cut, with 450-500 g/m2 per square metre indoors and 550-600 g/plant per plant outdoors as the figures you are working toward, at 26% 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 50/40 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
