Sour GirlEffects & Experience
Reported effects center on euphoric, uplifted. Sour Girl 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 Girl
Growing Sour Girl fits outdoor growers with at least 130 frost-free days; the balanced structure handles both heat and cool nights. Sour Girl 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 up to 400 g/m2 under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce up to 400 g/plant. Expected plant height is Short, 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 apply low-stress training in week 2 of veg, bend the main stem horizontally and tie down to expose lower nodes. The most common challenge growers report is training timing, top at the 4th node, not earlier and not later, for the best canopy distribution.
