Sour AmnesiaEffects & Experience
Sour Amnesia is best known for euphoric, relaxed, uplifted. 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 Amnesia
Growing Sour Amnesia fits cooler climates where photoperiod strains struggle to finish before frost, autoflower timing is calendar-driven, not daylight-driven. Sour Amnesia 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: defoliate strategically on day 21 of flower; remove fan leaves blocking interior bud sites without stripping the plant; 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.
