Amsterdam Seeds Company runs this as a indica feminized line — 25% THC lab range, fruity/citrus-dominant terps, 8-9 weeks from flip.

Smell-first, this one announces itself before the jar is halfway open — a dense wave of blueberry pastry with a citrus edge that sharpens as the buds dry down. Blue Cookies sits at 25% THC, so the effect lands with real weight: body-heavy, slow-moving relaxation that earns its 90% indica lineage. Flowering wraps in 8–9 weeks whether you run it in a tent or a greenhouse, and indoor growers pulling 450 g/m² report that the moderate difficulty rating is honest — she rewards clean technique but doesn't punish minor feeding errors.

The sweet, fruity terpene profile makes trimming day genuinely pleasant, and the dense bud structure holds up well in the humidity swings common to BC and Ontario falls. Keep airflow generous in the last two weeks to protect those tight colas. Best suited to growers who have a couple of runs under their belt and want a high-THC cultivar that finishes on a reliable schedule.

Genetics & Lineage

Blue Cookies traces its genetics to 90% Indica/10% Sativa (Amsterdam Seeds Company). This indica-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Amsterdam Seeds Company, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 25%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Blue Cookies delivers THC levels of 25%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing Blue Cookies

Blue 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 450g/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 40-50% 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

Blue Cookies features a fruity, citrus, sweet terpene profile that develops complexity throughout the flowering cycle. 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.

Medical Benefits

While individual experiences vary, Blue 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.
