Growing Sour Bubble
Growing Sour Bubble fits short outdoor seasons in the upper Midwest, Pacific Northwest, and Northeast, autoflower genetics finish in 70-90 days from seed regardless of latitude. Sour Bubble 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 350 g/m2 under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce up to 300 g/plant. Expected plant height is Medium, with intermediate cultivation difficulty. Practical tips that move the needle: feed cal-mag from week 2 onward at 2-3 mL per gallon, most reverse-osmosis and soft tap water setups need it; and flush nutrients in the final 10-14 days for cleaner flavor; trichomes finish properly even on plain pH-adjusted water. The most common challenge growers report is late-flower humidity if your indoor RH climbs above 55% during the final two weeks.
