Green KushEffects & Experience
Reported effects center on euphoric, calm. Green Kush pulls toward a balanced state where neither head nor body dominates — a profile that holds up across phenotypes when the seeds are grown to their potential.
Growing Green Kush
Growing Green Kush fits temperate and southern Canadian zones — coastal BC, Southern Ontario, and the Niagara region with mild September weather. Green Kush is photoperiod, which means you control when it flowers by switching from 18/6 (vegetative) to 12/12 (flowering). Most indoor growers veg for 4-6 weeks before the flip. Indoor yields land around 450-550 g/m² under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce 500-700 g/plant. Expected plant height is 120-180 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 feed cal-mag from week 2 onward at 2-3 mL per gallon — most reverse-osmosis and soft tap water setups need it. 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.
