About Ace Killer OG Auto
Does Ace Killer OG finish outdoors in Ireland? It does, planted out at the end of May and cut by early October. A compact 66/34 plant is easier to shelter and easier to hide, though the density that makes it worth growing is also what holds water after rain. Bloom takes 55-65 days, so the harvest date is set by the calendar far more than by your technique.
What should I expect to take off it? up to 350 g/m2 indoors and up to 400 g/plant outdoors are the published figures, and both assume a full light or a full season plus a root run to match. A tunnel gets you most of the way to the outdoor number; a windowsill will not. At 25% THC the effort is well spent either way.
Is it a sensible first grow? Reasonably. Anyone who has finished one grow will manage this one; it asks for consistency rather than expertise.
Other questions that come up about Ace Killer OG
Soil or coco? Coco with fertigation at EC 1.4-1.8 through bloom if you are there daily and want speed. Peat-free soil with slow amendments — fish, blood and bone, seaweed meal, rock phosphate — if you are not, and want flavour. Both suit this indica; the deciding factor is your week, not the plant.
How does it handle the weather here? The dense canopy shades itself, which is useful on the handful of genuinely warm days and a liability in a wet week. Mulch the root zone, water early, and keep air moving underneath.
When does bloom feed start? Within a week of the first pistils. The 66/34 balance shifts demand quickly at the transition — phosphorus and potassium up, nitrogen down. Soil growers top-dress; coco and hydro switch formula immediately.
Tunnel, outdoors or indoors? A tunnel is the best value of the three here. Indoors you own the 55-65 days of bloom completely; outdoors the plant gets light no lamp matches and can reach up to 400 g/plant, and pays for it in rain. Flowering: 55-65 days. Indoor yield: up to 350 g/m2. Outdoor yield: up to 400 g/plant. Plant height: Short. Rated intermediate difficulty.
What Ace Killer OG is like in practice
The catalogue lists relaxed, sleepy, happy, and that matches what growers here report back. At 25% 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 Linalool and Myrcene together leave a finish that keeps shifting across a session.
Suited to evenings in, recovery after work, and the hour before sleep.
Terpene breakdown
Primary: Linalool · Secondary: Myrcene · Tertiary: Caryophyllene. The three shift relative to each other across the cure. Straight off the dry the linalool dominates; three or four weeks sealed in glass at 16-18°C and the caryophyllene underneath comes up to meet it. Vaporising between 180°C and 195°C catches the widest span, because heat takes the lighter caryophyllene molecules first.
Who it suits
Ace Killer OG 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. Autoflowering genetics remove the light schedule from the equation, which matters in a shed or a spare room where full darkness is not realistic. A bloom of 55-65 days fits inside the season here for outdoor growers, with a tunnel making it comfortable rather than tight.
