China YunnanEffects & Experience
China Yunnan is best known for euphoric, calm. 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 China Yunnan
Growing China Yunnan fits cooler climates where photoperiod strains struggle to finish before frost, autoflower timing is calendar-driven, not daylight-driven. China Yunnan 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 250 grams under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce 250 grams per plant. Expected plant height is 3-4 Ft. Medium, 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 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 over-feeding nitrogen past week 1 of flower, switch to bloom nutrients within 7 days of seeing pistils.
