About Rainbow Kush Auto
The way to plan Rainbow Kush is backwards from the day you intend to cut, with 350-450 g/m2 per square metre indoors and 400-600 g/plant per plant outdoors as the figures you are working toward, at 22% THC. Count 8-10 weeks seed to harvest back from that date and you have your flip date. Weight comes on evenly across 8-10 weeks seed to harvest, 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 Myrcene, then Limonene, and Pinene underneath.
Difficulty: easy. In flower for 8-10 weeks seed to harvest. Stands 1.5 m. Indoors it returns 350-450 g/m2. Outdoors, 400-600 g/plant a plant.
