About Merlot OG Feminised
Does Merlot OG finish outdoors in Ireland? It does, planted out at the end of May and cut by early October. The 35/65 balance handles an Irish season without special treatment, which is most of the reason to choose it. 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? 400 gr/m² indoors and 500 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 15% 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 Merlot 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 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 35/65 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 500 grams, and pays for it in rain. Flowering: 60-70 days. Indoor yield: 400 gr/m². Outdoor yield: 500 grams. Plant height: 90-120 cm. Medium. Rated intermediate difficulty.
What Merlot OG is like in practice
The catalogue lists relaxed, calm, and that matches what growers here report back. At 15% THC this hybrid sits where the balance is the argument for it. Small doses stay functional, larger ones relax properly, and the 35/65 split means the direction is set by the amount rather than fixed by the plant. The Caryophyllene and Myrcene together leave warmth and spice, drying on the exhale.
Suited to most occasions, with the dose doing the steering.
Terpene breakdown
Primary: Caryophyllene · Secondary: Myrcene · Tertiary: Humulene. 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. Caryophyllene anchors it, myrcene holds the middle, and humulene sits behind both — the last of those being what separates this from other strains leading on the same terpene.
Who it suits
Merlot 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. 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 60-70 days fits inside the season here for outdoor growers, with a tunnel making it comfortable rather than tight.
