About Cannatonic CBD Feminised

Everything about Cannatonic CBD at harvest follows from one decision, which is when you stop. The figures are 500 g/m2 indoors and 500-650 g/plant outdoors, with resin filling towards 9% THC. The 48/52 balance gives steady gain with a lift in the closing fortnight. Outdoors, aim to be finished by mid-October rather than hoping for a dry third week of it.

Where the weight is won

Three parts of the 8-10 weeks of bloom account for most of the difference between a good result and an average one on a plant rated 500 g/m2 indoors and 500-650 g/plant outdoors.

The stretch, days 1-10 after the flip. Canopy height set here decides how evenly light lands for the rest of the run. Around a third is usual. A single pass of training across the tallest shoots keeps the top flat.

Weeks three to five. Myrcene production climbs through this stretch and responds to a 6-8°C gap between lights-on and lights-off. Outdoors an Irish September provides that without help; indoors it has to be built, at roughly 25°C by day and 18-20°C at night. Bloom feed goes potassium-forward around EC 1.6-1.8.

The final fortnight. Feeding stops, plain pH-corrected water goes on, and the loupe comes out daily. Ten to fifteen per cent amber sits in the middle of its range. Outdoors, that falls between late September and mid-October, and the forecast gets a say.

Flowering: 8-10 weeks. Indoor yield: 500 g/m2. Outdoor yield: 500-650 g/plant. Plant height: Short. Rated intermediate difficulty.

What Cannatonic CBD is like in practice

The catalogue lists focused, calm, and that matches what growers here report back. At 9% THC this cbd sits where the balance is the argument for it. Small doses stay functional, larger ones relax properly, and the 48/52 split means the direction is set by the amount rather than fixed by the plant. The Myrcene and Linalool together leave earth and faint sweetness, with fruit at the end.

Suited to most occasions, with the dose doing the steering.

Terpene breakdown

Primary: Myrcene · Secondary: Linalool · Tertiary: Pinene. Temperature decides how much of this profile survives. Low vaporisation at 180-188°C keeps linalool and pinene audible over the myrcene; run it hotter, or burn it, and all three collapse into one note that is pleasant enough and tells you nothing.

Who it suits

Cannatonic CBD suits growers with the fundamentals in place. Understand pH, rough nutrient ratios and a light cycle before committing to it; it asks for competence rather than expertise. Photoperiod genetics leave plant size and harvest date under your control — veg longer for a bigger plant, or flip early when the ceiling is low. A bloom of 8-10 weeks fits inside the season here for outdoor growers, with a tunnel making it comfortable rather than tight.

Cannatonic CBD Feminised — Breeder Information

Royal King Genetics

Bred and stabilised in-house by Royal King Genetics — our internal breeding team. Every batch is QC'd and germ-tested above 99% before it ships. Read the full breeding process and about page.

Breeding Programme
CBD Programme — four-generation cannabinoid ratio stabilisation
Stabilisation Notes — What This Means for Your Grow

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.

Breeding Goal

Pin the recessive CBD-dominant trait in Cannatonic for therapeutic reliability.

Selection Focus

Chosen for CBD:THC ratio expression, low-THC consistency and a bud structure suited to medical production.

Pollen / Mother Source

Royal King Genetics breeding facility — pollen from internally selected sibling males of the recurrent parent.
