Growing Sour Alien
Growing Sour Alien fits guerrilla growers and balcony cultivators, since the plant ignores light cycle and finishes before fall rains arrive. Sour Alien 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 up to 300 g/m2 under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce up to 200 g/plant. Expected plant height is Short, 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.
