Smell-first: crack a jar of this Nirvana cut and the fruity-sweet wave hits before you've finished exhaling — there's a soft earthiness underneath that keeps it from reading as candy. Green Poison Feminized sits at 20% THC with a 7–9 week flower window, which makes it one of the faster-finishing indicas worth running indoors or out across most Canadian provinces. Yields land in the 400–500 g/m² range under decent light, so you're not gambling on a marginal return for the time invested.

Difficulty is rated moderate, meaning you don't need a season of grow logs behind you, but you'll want to dial in your VPD and not skip the mid-flower feed bump. The effect leans toward body-heavy relaxation without completely flattening focus — reasonable for evening use without being a write-off. Good pick for growers who want a reliable, fast-finishing indica without paying a boutique tax.

Growing Green Poison

Green Poison is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

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. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.
