Sister GlueEffects & Experience
Reported effects center on happy, euphoric. Sister Glue pulls toward a balanced state where neither head nor body dominates — a profile that holds up across phenotypes when the seeds are grown to their potential.
Growing Sister Glue
Growing Sister Glue fits temperate and southern Canadian zones — coastal BC, Southern Ontario, and the Niagara region with mild September weather. Sister Glue is photoperiod, which means you control when it flowers by switching from 18/6 (vegetative) to 12/12 (flowering). Most indoor growers veg for 4-6 weeks before the flip. 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 120-180 cm, 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 maintain canopy airflow with an oscillating fan moving air through the leaves, not just above them, to prevent powdery mildew. The most common challenge growers report is late-flower humidity if your indoor RH climbs above 55% during the final two weeks.
