Growing Mac 1
Growing Mac 1 fits short outdoor seasons in the upper Midwest, Pacific Northwest, and Northeast, autoflower genetics finish in 70-90 days from seed regardless of latitude. Mac 1 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: flush nutrients in the final 10-14 days for cleaner flavor; trichomes finish properly even on plain pH-adjusted water; 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.
