About Mt. Rainier Feminised
The way to plan Mt. Rainier is backwards from the day you intend to cut, with Up to 400g/m² per square metre indoors and Up to 500 gr per plant outdoors as the figures you are working toward, at 20% 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 43/57 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: intermediate. In flower for 8-9 weeks. Stands Short. Indoors it returns Up to 400g/m². Outdoors, Up to 500 gr a plant.
