Sour OGEffects & Experience
Reported effects center on focused, energetic, calm. Sour OG 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 Sour OG
Growing Sour OG fits outdoor growers with at least 130 frost-free days; the balanced structure handles both heat and cool nights. Sour OG 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 450g/m2 under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce 500g/plant. Expected plant height is Medium (5 to 8 FT), 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 defoliate strategically on day 21 of flower; remove fan leaves blocking interior bud sites without stripping the plant. The most common challenge growers report is training timing, top at the 4th node, not earlier and not later, for the best canopy distribution.
