Sour KushEffects & Experience
Sour Kush is best known for relaxed, happy, euphoric. The effects come on within the first 10 minutes and settle into a stable plateau that lasts 90 minutes to two hours at typical doses. Growers and users consistently note that the high stays true to its profile rather than drifting, what you feel in the first 20 minutes is what you have for the next 90.
Growing Sour Kush
Growing Sour Kush fits cooler climates where photoperiod strains struggle to finish before frost, autoflower timing is calendar-driven, not daylight-driven. Sour 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 up to 450 g/m2 under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce up to 550 g/plant. Expected plant height is Medium, 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 defoliate strategically on day 21 of flower; remove fan leaves blocking interior bud sites without stripping the plant. The most common challenge growers report is calcium and magnesium supplementation under bright LED lighting; cal-mag at 2-3 mL/gal from week 2 prevents the most common deficiency.
