Green PoisonEffects & Experience
The dominant effects of Green Poison are euphoric, creative, and the experience is more nuanced than a simple high/low/sedating label would suggest. Onset is gradual rather than abrupt, the peak holds for roughly an hour, and the comedown is smooth, which is why this strain shows up in so many "daily driver" lists from experienced consumers.
Growing Green Poison
Growing Green Poison fits guerrilla growers and balcony cultivators across all 50 states, since the plant ignores light cycle and finishes before fall rains arrive. Green Poison 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 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 60-100 cm, 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 top once at the 4th node to encourage 4-6 even main colas instead of one dominant cola. The most common challenge growers report is training timing, top at the 4th node, not earlier and not later, for the best canopy distribution.
