About Vader OG Feminised

Does Vader OG finish outdoors in Ireland? It does, planted out at the end of May and cut by early October. A compact 76/24 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 60-70 days, so the harvest date is set by the calendar far more than by your technique.

What should I expect to take off it? 350 gr/m² indoors and 350 grams 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 27% 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 Vader 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 76/24 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 60-70 days of bloom completely; outdoors the plant gets light no lamp matches and can reach 350 grams, and pays for it in rain. Flowering: 60-70 days. Indoor yield: 350 gr/m². Outdoor yield: 350 grams. Plant height: 90-120 cm. Medium. Rated beginner to intermediate difficulty.

Flavour, aroma and effect

Vader OG arrives in order. The first draw at 27% THC gives earth and musk, coating rather than sharp. The relaxed, sleepy, happy character follows in minutes, as weight behind the eyes that works down through the shoulders. By a quarter of an hour it reads as physical stillness rather than sedation — a strong disinclination to stand up. Two to three hours at a sensible dose. Caryophyllene underneath contributes warmth that keeps it anchored.

Terpene breakdown

Primary: Myrcene · Secondary: Caryophyllene · Tertiary: Linalool. Temperature decides how much of this profile survives. Low vaporisation at 180-188°C keeps caryophyllene and linalool 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

Who does well with Vader OG? Indoor growers who want to choose their own timeline. Tunnel growers who want to decide when flowering starts rather than letting August decide it. Anyone with the space to veg it properly first. Rated beginner to intermediate, which means a moderate learning curve that rewards attention without needing specialist kit.

Breeding Goal

Translate a clone-only recent-era cultivar to seed without losing the mother profile.

Selection Focus

Chosen for purple/dark expression where it shows, dense bud structure and a true indica relaxation profile.
