Jean Guy Feminised

The way to plan Jean Guy is backwards from the day you intend to cut, with < 155 g/m² (< 150 g/m²) per square metre indoors and 283-425 g/plant (~ 400 g/plant) per plant outdoors as the figures you are working toward, at 19% THC. Count 10 weeks back from that date and you have your flip date. Weight comes on evenly across 10 weeks, with a late surge that punishes impatience. The 40/60 balance gives you stacking density and broad trichome cover together. Outdoors, late March to late April is the sweet spot — after the summer humidity has broken, before the first Highveld frost.

Yield on Jean Guy — the < 155 g/m² (< 150 g/m²) indoors and 283-425 g/plant (~ 400 g/plant) outdoors quoted above — is decided in three short stretches of the 10 weeks bloom rather than evenly across it.

The first ten days after the flip. Whatever stretch happens here sets your canopy, and an uneven canopy wastes light for the remainder of the grow. Stretch of 30-40% is normal. One round of low-stress training on the tallest shoots levels it out.

Weeks three to five. This is when caryophyllene production climbs, and it answers to the gap between day and night temperature rather than to either number on its own. Keep at least 6-8°C between them. Outdoor growers in the interior provinces get that swing free in March and April; indoors, aim for 25-26°C lights-on against 18-20°C lights-off, with potassium-led bloom feed at EC 1.6-1.8.

The last ten to fourteen days. Stop feeding, flush with pH-corrected water, and read trichomes daily under a 60x loupe. Cut at 10-15% amber to keep both sides of the hybrid in play. Outdoors that usually lands between late March and mid-April.

Difficulty: easy. In flower for 10 weeks. Stands Small (0-120 cm). Indoors it returns < 155 g/m² (< 150 g/m²). Outdoors, 283-425 g/plant (~ 400 g/plant) a plant.

The effects most commonly reported for this cultivar are giggly, talkative, uplifted. At 19% THC it sits in a bracket where flexibility is the point. Lower doses read clear and functional in the morning, higher doses read relaxed in the evening. Because the 40/60 split is even, direction is set by how much you take rather than fixed by the genetics. The Caryophyllene/Myrcene pairing leaves a warm spice that dries slightly on the exhale on the palate.

Where it fits: most occasions, with the dose adjusted to whatever the situation asks for.

Leading with Caryophyllene, then Myrcene, and Humulene underneath. Read across a cure, these three compounds do not stay in the same order. Fresh off the dry, caryophyllene leads. After three or four weeks in sealed glass at 16-18°C the humulene undertone comes up and the bouquet gains a layer it did not have at harvest. Vaporising between 180°C and 195°C captures the widest span of them — run it hotter and the volatile humulene molecules are the first thing you lose.

Jean Guy is a reasonable fit for growers with the basics already in place. Understand pH, know roughly what nutrient ratios do, and be able to hold a light cycle — it will not carry you, but it does not punish the occasional slip either. Photoperiod genetics leave size and timing in your hands — hold it in veg for a bigger plant, or flip early when headroom is the constraint. A September-to-May outdoor season comfortably covers a 10 weeks bloom in the frost-free provinces. Posted discreetly anywhere in South Africa, with sourced grow figures shown on every strain page.
