About Holy Grail Kush Feminised

The way to plan Holy Grail Kush is backwards from the day you intend to cut, with 480 - 650 g/m2 per square metre indoors and ~795 g/plant per plant outdoors as the figures you are working toward, at 22% THC. Count 8-10 weeks back from that date and you have your flip date. Weight comes on evenly across 8-10 weeks, with a late surge that punishes impatience. The 60/40 balance gives you stacking density and broad trichome cover together. Outdoors, late March to late April is the sweet spot β€” after the summer humidity has broken, before the first Highveld frost.

The Aromatic Three

Leading with Myrcene, then Limonene, and Pinene underneath.

Difficulty: medium. In flower for 8-10 weeks. Stands Medium. Indoors it returns 480 - 650 g/m2. Outdoors, ~795 g/plant a plant.

Breeding Goal

Recreate the Holy Grail Kush clone-only cut in stable seed form.
