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 8-10 weeks 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 450-550 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.

Schrom flowers in 8-10 weeks once you flip to 12/12 light cycle. Outdoor harvest typically lands in late September to mid-October across most US zones.
What is the THC content of Schrom?+
Schrom tests at approximately 18% THC when grown to its potential. Real-world numbers depend on grow conditions, harvest timing, and curing, well-grown phenotypes can land at the high end of that range, while poorly cured flower tests lower.
Is Schrom good for beginner growers?+
Schrom is rated intermediate difficulty. Photoperiod genetics give you control over plant size and harvest timing, which means a bit more responsibility for getting the schedule right. Most growers with one harvest behind them handle this strain without difficulty.
