Grease MonkeyEffects & Experience
The dominant effects of Grease Monkey are relaxed, happy, euphoric, and the experience is more nuanced than a simple high/low/sedating label would suggest. Onset is gradual rather than abrupt, the peak holds for roughly an hour, and the comedown is smooth, which is why this strain shows up in so many "daily driver" lists from experienced consumers.
Growing Grease Monkey
Growing Grease Monkey fits short outdoor seasons in the upper Midwest, Pacific Northwest, and Northeast, autoflower genetics finish in 70-90 days from seed regardless of latitude. Grease Monkey runs on an 18/6 light schedule from seed to harvest, autoflower genetics ignore photoperiod, so there is no flip and no light-cycle change. Indoor yields land around 350–550 g/m² under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce 400–700 g/plant. Expected plant height is 100–140 cm, with intermediate cultivation difficulty. Practical tips that move the needle: maintain canopy airflow with an oscillating fan moving air through the leaves, not just above them, to prevent powdery mildew; and top once at the 4th node to encourage 4-6 even main colas instead of one dominant cola. The most common challenge growers report is calcium and magnesium supplementation under bright LED lighting; cal-mag at 2-3 mL/gal from week 2 prevents the most common deficiency.
