Silver KushEffects & Experience
Reported effects center on happy, relaxed, uplifted. Silver Kush 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 Silver Kush
Growing Silver Kush fits short Canadian outdoor seasons across the Prairies, Atlantic provinces, and northern BC — autoflower genetics finish in 70-90 days from seed regardless of latitude. Silver 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 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: flush nutrients in the final 10-14 days for cleaner flavor; trichomes finish properly even on plain pH-adjusted water; and top once at the 4th node to encourage 4-6 even main colas instead of one dominant cola. 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.
