Sister GlueEffects & Experience
Sister Glue is best known for 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 Sister Glue
Growing Sister Glue fits cooler climates where photoperiod strains struggle to finish before frost, autoflower timing is calendar-driven, not daylight-driven. Sister Glue 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 500 g/plant. Expected plant height is 3-4 Ft. Medium, with intermediate cultivation difficulty. Practical tips that move the needle: top once at the 4th node to encourage 4-6 even main colas instead of one dominant cola; 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 training timing, top at the 4th node, not earlier and not later, for the best canopy distribution.
