The specs in one line: 15% THC, <2% CBD, 8-9 weeks flowering, 350g/m2 reported. Best indoor or outdoor. moderate grow.

Smell-first: crack a jar of Monster Cookies and the room fills with damp soil and brown sugar — earthy with just enough sweetness to keep you curious. Amsterdam Seeds Company built this feminized strain around a proprietary cross that finishes in 8–9 weeks, so it fits neatly into a standard indoor cycle without pushing your patience. At 15% THC it won't flatten inexperienced users, but the effects settle into a relaxed, slightly heavy evening state that most people find genuinely useful for winding down. Yields sit around 350g/m² indoors, which is honest mid-range production — nothing to brag about, nothing to complain about either. The plant handles both indoor and outdoor environments and asks for moderate care: decent training, consistent feeding, nothing exotic.

Good pick for a grower who's moved past beginner mistakes and wants a low-drama feminized strain that produces consistent, flavorful buds without demanding a lot of technical overhead.

Growing Monster Cookies

Monster Cookies 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 8-9 weeks with yields of 350g/m2. Plants typically reach 100-160cm 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 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

Monster Cookies features a earthy, sweet terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Monster Cookies is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
