SchromEffects & Experience
Reported effects center on happy, relaxed, uplifted. Schrom pulls toward mental clarity, conversation, and a light, mobile body feel — a profile that holds up across phenotypes when the seeds are grown to their potential.
Growing Schrom
Growing Schrom fits mild coastal and southern Canadian climates with dry late-summer weather to support the longer flower window. Schrom 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: top once at the 4th node to encourage 4-6 even main colas instead of one dominant cola; and feed cal-mag from week 2 onward at 2-3 mL per gallon — most reverse-osmosis and soft tap water setups need it. The most common challenge growers report is training timing — top at the 4th node, not earlier and not later, for the best canopy distribution.
