G13 WidowEffects & Experience
G13 Widow is best known for relaxed, sleepy, happy. The effects come on within the first 10 minutes and settle into a stable plateau that lasts 90 minutes to two hours at typical doses. Growers and users consistently note that the high stays true to its profile rather than drifting, what you feel in the first 20 minutes is what you have for the next 90.
Growing G13 Widow
Growing G13 Widow fits guerrilla growers and balcony cultivators, since the plant ignores light cycle and finishes before fall rains arrive. G13 Widow runs on an 18/6 light schedule from seed to harvest, autoflower genetics ignore photoperiod, so there is no flip and no light-cycle change. Indoor yields land around up to 300 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 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.
