Smell-first, this one telegraphs itself before the jar is even open — a dense, fruity-sweet wave with enough earthiness underneath to keep it grounded rather than candy-sweet. Green Poison Feminized from Nirvana Seeds is an indica-leaning strain sitting at 20% THC, and it earns that number through a relatively quick 7–9 week flower cycle that rewards growers who don't overcomplicate their feeding schedule. Expect 400–500g/m² indoors when light and airflow are dialed in; the plant handles both indoor and outdoor environments without throwing fits, which makes it a reasonable pick for cultivators who are still getting comfortable with their setup.

The effect leans toward full-body relaxation with enough of a mental lift to stay functional for a few hours — not a couch-lock knockout, but not a daytime strain either. Moderate difficulty means beginners may need one run to understand the plant before hitting those top-end yields consistently.

Growing Green Poison

Indoor Growing: Expect a flowering time of 7-9 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 40-50% during flowering.

Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate.
