About Green Goblin Feminised

Does Green Goblin finish outdoors in Ireland? It does, planted out at the end of May and cut by early October. The 48/52 balance handles an Irish season without special treatment, which is most of the reason to choose it. Bloom takes 7-9 weeks, so the harvest date is set by the calendar far more than by your technique.

What should I expect to take off it? 500 g/m2 indoors and 600 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 20% 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 Green Goblin

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 hybrid; the deciding factor is your week, not the plant.

How does it handle the weather here? Hybrid vigour covers most of what an Irish summer does. Keep the root zone under 28°C and do not transplant into a warm spell.

When does bloom feed start? Within a week of the first pistils. The 48/52 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 7-9 weeks of bloom completely; outdoors the plant gets light no lamp matches and can reach 600 g/plant, and pays for it in rain. Flowering: 7-9 weeks. Indoor yield: 500 g/m2. Outdoor yield: 600 g/plant. Plant height: Medium. Rated easy difficulty.

Flavour, aroma and effect

Green Goblin arrives in order. The first draw at 20% THC gives citrus with a bitter edge that lifts off the palate. The euphoric, calm character follows in minutes, as head and body together. Thinking stays clear while the muscles let go by degrees, which is what makes the dose, rather than the genetics, the thing that decides the evening. Caryophyllene underneath contributes warmth that keeps it anchored.

Terpene breakdown

Primary: Limonene · 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 limonene; 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 Green Goblin? 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.
