Growing Critical Kush
Growing Critical Kush fits short outdoor seasons in the upper Midwest, Pacific Northwest, and Northeast, autoflower genetics finish in 70-90 days from seed regardless of latitude. Critical Kush 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 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 60-100 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 over-feeding nitrogen past week 1 of flower, switch to bloom nutrients within 7 days of seeing pistils.
Critical KushLineage & Genetics
Critical Kush traces back to Big Bud x Skunk #1, a cross that has shaped the modern cannabis menu for over a decade. The parental genetics explain the compact structure and resin production you see in the finished plant. Royal King Genetics works from a verified mother selection, so seeds run true to type rather than producing the wide phenotype variation cheaper sources are known for.
