OG Chem Feminised

Here is what OG Chem delivers at harvest: Up to 400g/m² per square metre indoors, Up to 500 gr per plant outdoors in Irish conditions, with resin production peaking at 20% THC. Those numbers tell a story when you work backwards through the 55-65 days window. Unlike quick-finishing indicas, this 30/70 cultivar distributes its weight gain across the full flowering period. Patience is non-negotiable — growers who chop early because they are anxious about autumn weather sacrifice 20-25% of their potential yield. For outdoor grows in Ireland, that patience runs straight into the weather: the harvest window is late September to early October and it does not move, so a long-flowering cultivar has to go out early or go under cover. The limonene-dominant terpene profile reaches peak complexity only in the final fortnight.

To reach the upper end of this strain's yield potential (Up to 400g/m² indoors, Up to 500 gr outdoors), focus your efforts on three critical windows during the 55-65 days period.

Window 1: The first 10 days after flowering begins. Stretch management determines canopy uniformity, which directly impacts light distribution and final yield. Stretch can reach 50-60% of pre-flower height. Supercrop any branches that outpace the canopy within the first week to maintain an even light field.

Window 2: Weeks 3-5 of bloom. Limonene 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 5-10% amber to preserve the cerebral, uplifting character. Outdoor growers: this window typically falls through the second half of September.

Flowering: 55-65 days. Indoor yield: Up to 400g/m². Outdoor yield: Up to 500 gr. Plant height: 90-120 cm. Medium. Rated easy difficulty.

Irish users report euphoric, happy, uplifted as the defining characteristics, and our experience aligns with that consensus. At 20% THC, this sativa sits in a potency bracket where most users find a productive sweet spot. Vaporised at 175-185°C, the initial effect is a noticeable uplift in mood and mental energy that pairs well with creative projects, hikes, or a long afternoon braai. The body remains light and mobile throughout, making this a genuine daytime option for those with THC tolerance. The Limonene/Terpinolene terpene combination imparts a flavour that lingers on the palate — zesty and bright with a clean, refreshing aftertaste.

Ideal settings: creative pursuits, social gatherings, outdoor adventures, and daytime leisure.

Primary: Limonene · Secondary: Terpinolene · Tertiary: Pinene. Flavour translation from flower to vapour and smoke differs with this terpene combination. Low-temperature vaporisation (180-188°C) highlights the terpinolene and pinene notes whilst keeping limonene as a foundation. Higher temperatures or combustion flatten the profile into a single-note experience — still pleasant, but lacking the complexity that makes this cultivar genuinely interesting to those who appreciate flavour.

OG Chem 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 55-65 days bloom period comfortably for outdoor growers in the warmer, frost-free counties.
