About Critical Plus Feminised
Everything about Critical Plus at harvest follows from one decision, which is when you stop. The figures are 625 g/m2 indoors and 1300 g/plant outdoors, with resin filling towards 23% THC. The 61/39 balance gives steady gain with a lift in the closing fortnight. Outdoors, aim to be finished by mid-October rather than hoping for a dry third week of it.
Where the weight is won
Three parts of the 45-50 days of bloom account for most of the difference between a good result and an average one on a plant rated 625 g/m2 indoors and 1300 g/plant outdoors.
The stretch, days 1-10 after the flip. Canopy height set here decides how evenly light lands for the rest of the run. Around a third is usual. A single pass of training across the tallest shoots keeps the top flat.
Weeks three to five. Caryophyllene production climbs through this stretch and responds to a 6-8°C gap between lights-on and lights-off. Outdoors an Irish September provides that without help; indoors it has to be built, at roughly 25°C by day and 18-20°C at night. Bloom feed goes potassium-forward around EC 1.6-1.8.
The final fortnight. Feeding stops, plain pH-corrected water goes on, and the loupe comes out daily. Ten to fifteen per cent amber sits in the middle of its range. Outdoors, that falls between late September and mid-October, and the forecast gets a say.
Flowering: 45-50 days. Indoor yield: 625 g/m2. Outdoor yield: 1300 g/plant. Plant height: Medium. Rated easy difficulty.
What Critical Plus is like in practice
The catalogue lists euphoric, focused, and that matches what growers here report back. At 23% THC this hybrid sits where the balance is the argument for it. Small doses stay functional, larger ones relax properly, and the 61/39 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. Temperature decides how much of this profile survives. Low vaporisation at 180-188°C keeps myrcene and humulene audible over the caryophyllene; run it hotter, or burn it, and all three collapse into one note that is pleasant enough and tells you nothing.
Who it suits
Critical Plus 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 45-50 days fits inside the season here for outdoor growers, with a tunnel making it comfortable rather than tight.
