Cold War KushEffects & Experience
Cold War Kush is best known for relaxed, sleepy, happy. The effects come on within the first 10 minutes and settle into a stable plateau that lasts 90 minutes to two hours at typical doses. Growers and users consistently note that the high stays true to its profile rather than drifting — what you feel in the first 20 minutes is what you have for the next 90.
Growing Cold War Kush
Growing Cold War Kush fits cooler Canadian climates and high-altitude growers, where the compact structure resists wind and the short flower beats early frost. Cold War 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 over-feeding nitrogen past week 1 of flower — switch to bloom nutrients within 7 days of seeing pistils.
