About Blue Zushi Feminised
The way to plan Blue Zushi is backwards from the day you intend to cut, with 500 g/m2 per square metre indoors and 500-750 g/plant per plant outdoors as the figures you are working toward, at 28% THC. Count 8-9 weeks back from that date and you have your flip date. Weight comes on evenly across 8-9 weeks, with a late surge that punishes impatience. The 35/65 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 Myrcene, and Humulene underneath.
Difficulty: easy. In flower for 8-9 weeks. Stands Up to 130 cm. Indoors it returns 500 g/m2. Outdoors, 500-750 g/plant a plant.
