Jean Guy Feminised

Here is what Jean Guy delivers at harvest: < 155 g/m² (< 150 g/m²) per square metre indoors, 283-425 g/plant (~ 400 g/plant) per plant outdoors in Irish conditions, with resin production peaking at 19% THC. Those numbers tell a story when you work backwards through the 10 weeks window. Weight distribution across the 10 weeks cycle is pleasingly even, with a noticeable surge in the closing two weeks that rewards growers who resist harvesting prematurely. The 40/60 balance means you get both calyx stacking density and respectable trichome spread. For outdoor growers, the ideal harvest window lands between mid-September and the first week of October — late enough to capture the full caryophyllene terpene development, early enough to beat the autumn rain that ends the Irish season.

To reach the upper end of this strain's yield potential (< 155 g/m² (< 150 g/m²) indoors, 283-425 g/plant (~ 400 g/plant) outdoors), focus your efforts on three critical windows during the 10 weeks period.

Window 1: The first 10 days after flowering begins. Stretch management determines canopy uniformity, which directly impacts light distribution and final yield. Moderate 30-40% stretch is typical. One round of low-stress training on the tallest shoots keeps everything level.

Window 2: Weeks 3-5 of bloom. Caryophyllene terpene biosynthesis ramps up during this period. Maintain a day/night temperature differential of at least 6-8°C to encourage terpene accumulation. Outdoors in Ireland the sea keeps that swing narrow — a maritime climate has a smaller diurnal range than a continental one, and the midland counties away from the coast are the only places that reliably deliver it. Indoor cultivators should target 25-26°C during lights-on and 18-20°C during lights-off. Supplement with potassium-heavy bloom nutrients at EC 1.6-1.8.

Window 3: Final 10-14 days before harvest. Cease all nutrient input and flush with pH-adjusted water. Monitor trichomes daily with a 60x jeweller's loupe — harvest at 10-15% amber for a balanced effect. Outdoor growers: this window typically falls through the second half of September.

Flowering: 10 weeks. Indoor yield: < 155 g/m² (< 150 g/m²). Outdoor yield: 283-425 g/plant (~ 400 g/plant). Plant height: Small (0-120 cm). Rated easy difficulty.

Irish users report giggly, talkative, uplifted as the defining characteristics, and our experience aligns with that consensus. At 19% THC, this hybrid sits in a potency bracket where versatility is the main advantage. Morning users report functional clarity at lower doses. Evening users report satisfying relaxation at higher doses. The 40/60 balance means the dominant effect direction shifts with consumption amount rather than being locked into a single character. The Caryophyllene/Myrcene terpene combination imparts a flavour that lingers on the palate — warm and spiced, drying slightly on the exhale.

Ideal settings: adaptable across occasions — adjust dose to match the energy level your situation calls for.

Primary: Caryophyllene · Secondary: Myrcene · Tertiary: Humulene. Together these three compounds construct an aromatic signature that evolves throughout the curing process. Freshly dried flower leads with caryophyllene presence, but after three to four weeks in sealed glass jars at 16-18°C, the humulene undertone strengthens and the overall bouquet develops a layered complexity. Vaporisation between 180°C and 195°C captures the broadest spectrum of these terpenes — higher temperatures degrade the more volatile humulene molecules first.

Jean Guy suits growers with fundamental skills already established. You should understand pH management, basic nutrient ratios, and light cycle requirements before committing to this cultivar — it will not hold your hand, but it will not punish minor mistakes harshly either. Photoperiod genetics give you complete control over plant size and harvest timing — extend the vegetative phase for larger plants or flip early for a quicker turnaround in compact spaces. The Irish growing season (September through May) accommodates the 10 weeks bloom period comfortably for outdoor growers in the warmer, frost-free counties.
