About Double Purple Doja Feminised

Does Double Purple Doja finish outdoors in Ireland? It does, planted out at the end of May and cut by early October. A compact 68/32 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 450 g/m2 indoors and up to 550 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 17% 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 Double Purple Doja

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 68/32 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 550 g/plant, and pays for it in rain. Flowering: 55-65 days. Indoor yield: up to 450 g/m2. Outdoor yield: up to 550 g/plant. Plant height: 75-200 cm. Rated easy difficulty.

Flavour, aroma and effect

Double Purple Doja arrives in order. The first draw at 17% THC gives earth and musk, coating rather than sharp. The euphoric, creative, calm 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. This is a combination that turns up repeatedly in cultivars people rate, and it is usually what gets commented on when a jar is opened for the first time after a proper cure. Myrcene anchors it, caryophyllene holds the middle, and linalool sits behind both — the last of those being what separates this from other strains leading on the same terpene.

Who it suits

Who does well with Double Purple Doja? 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 easy, which means a moderate learning curve that rewards attention without needing specialist kit.
