About Ghost OG Feminised
Days 1-14, germination and early veg. Ghost OG generally cracks within about two days on damp kitchen paper and is above the medium by day three. The first fortnight came in low and thickset, wide seed leaves followed by the broad dark fans this side of the genetics gives. Four nodes by day 14, the gaps between them already short. Keep the humidity near 70% and damping off stops being a concern.
Weeks 3-6, veg. Branching filled out fast after a single top at node four, holding a 60cm square and staying under 40cm — which is what makes this shape practical in the small tents most people actually have room for.
Bloom, weeks 1-10. The 75/25 character came through clearly. Myrcene was noticeable by week three and kept building; resin was obvious without a loupe from about week five. Indoor yield: 550-650 g/m2. Height: 150 cm. Tested at 23%. Rated beginner.
The rest of the run
Weeks 4-6, mid-bloom. Loose clusters from week three closed up into defined colas. Density climbed daily until a bud squeezed like a firm ball by week five. Fan leaves came off at the start of week four to keep air under the canopy, which mattered — an Irish autumn room sits damp, and flower this tight does not tolerate still air.
Ripening, weeks 8-10. Plain water for the last ten days. Myrcene was strong enough by then that carbon filtration was not optional in a terraced house. Heads went clear to milky over the final fortnight, amber showing on sugar leaves first, and around 15% amber on the calyxes is a defensible place to stop.
Drying and curing. Hung whole in the dark at 17°C and 58% humidity for twelve days, both held by a dehumidifier because an October room here will hold neither. Stems snapped instead of bending, which is the only test worth trusting. Four weeks in glass after that. The 550-650 g/m2 figure held up. Humulene was far more present after the cure than at harvest — the cure makes flavour, it does not merely preserve it.
Flowering: 8-10 weeks. Indoor yield: 550-650 g/m2. Outdoor yield: 500-600 g/plant. Plant height: 150 cm. Rated beginner difficulty. Feminised seeds.
What Ghost OG is like in practice
The catalogue lists happy, relaxed, uplifted, and that matches what growers here report back. At 23% THC this indica sits where the dose is the whole question. One bowl through a vaporiser at 185°C leaves the head working and the body easy, which is what most people are after on a weeknight. More than that moves it firmly towards sedation. The Myrcene and Humulene together leave earth and faint sweetness, with fruit at the end.
Suited to evenings in, recovery after work, and the hour before sleep.
Terpene breakdown
Primary: Myrcene · Secondary: Humulene · Tertiary: Linalool. The three shift relative to each other across the cure. Straight off the dry the myrcene dominates; three or four weeks sealed in glass at 16-18°C and the linalool underneath comes up to meet it. Vaporising between 180°C and 195°C catches the widest span, because heat takes the lighter linalool molecules first.
Who it suits
Ghost OG suits growers at any stage, a first outdoor season included. It tolerates the ordinary early mistakes — watering by habit rather than by weight, a feed that drifts, a tunnel that runs cold overnight — without the crop coming apart. 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.
