G13 WidowEffects & Experience
Reported effects center on relaxed, sleepy, happy. G13 Widow pulls toward physical relaxation and a quiet, observational headspace, a profile that holds up across phenotypes when the seeds are grown to their potential.
Growing G13 Widow
Growing G13 Widow fits shorter outdoor seasons, Pacific Northwest, New England, Great Lakes, where 7-9 week flowering finishes ahead of October rains. G13 Widow 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: defoliate strategically on day 21 of flower; remove fan leaves blocking interior bud sites without stripping the plant; and maintain canopy airflow with an oscillating fan moving air through the leaves, not just above them, to prevent powdery mildew. The most common challenge growers report is late-flower humidity if your indoor RH climbs above 55% during the final two weeks.
