SchromStrain, Effects, Genetics, Grow Guide & Where to Buy
Few cultivars carry the cult following Schrom has built across the US grow community , and the appeal is easy to explain. It is a sativa-dominant (20% indica / 80% sativa) testing at roughly 18% THC, with a flowering window of 65-75 days under a 12/12 photoperiod. What follows is a complete reference: terpene-led effects, genetic background, indoor and outdoor grow guidance, and the fastest way to get Schrom seeds shipped to your state.

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 subtropical and Mediterranean 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 g/m² under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce up to 450 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 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.
