Growing Crystal Coma
Growing Crystal Coma fits short outdoor seasons in the upper Midwest, Pacific Northwest, and Northeast — autoflower genetics finish in 70-90 days from seed regardless of latitude. Crystal Coma 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: apply low-stress training in week 2 of veg — bend the main stem horizontally and tie down to expose lower nodes; and maintain canopy airflow with an oscillating fan moving air through the leaves, not just above them, to prevent powdery mildew. 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.
