About Cannatonic CBD Feminised
The way to plan Cannatonic CBD is backwards from the day you intend to cut, with 500 g/m2 per square metre indoors and 500-650 g/plant per plant outdoors as the figures you are working toward, at 9% 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 48/52 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 Linalool, and Pinene underneath.
Difficulty: intermediate. In flower for 8-10 weeks. Stands Short. Indoors it returns 500 g/m2. Outdoors, 500-650 g/plant a plant.

Cannatonic CBD Feminised — Breeder Information
Royal King GeneticsRecreated and stabilised by Royal King Genetics, the breeding team behind this catalogue. Seed lots are germination-tested before they ship. More on the breeding process and about page.
Cannatonic is a CBD-stabilised line worked over four rounds to fix CBD-dominance into the population. CBD-dominance is recessive — multi-generation selection is required — and at F4 the CBD:THC ratio expresses uniformly across the pack.
Pin the recessive CBD-dominant trait in Cannatonic for therapeutic reliability.
Chosen for CBD:THC ratio expression, low-THC consistency and a bud structure suited to medical production.
Royal King Genetics breeding facility — pollen from internally selected sibling males of the recurrent parent.
