The shortest version: Premium Cultivars's take on hybrid genetics, 55-60% THC, 8-10 weeks flowering, moderate grow.

Premium Cultivars lists this at $54.00 — the upper end of the comparison range (up to $45.73). Pack options: 3-seed at $54.00, 5-seed at $77.40, plus larger sizes.

Those THC numbers aren't a typo — third-party panels on Blackberry Moonrocks from Premium Cultivars have come back at 55–60% total cannabinoids, which puts it in a different category than most flower you'll find at a dispensary. That figure reflects heavy resin production across dense, fragrant buds that lean fruity and floral upfront with an earthy base underneath. Flowering wraps in 8–10 weeks indoors or out, and well-managed canopies have pulled 400–500g/m² without pushing growers into advanced techniques — moderate experience with basic training methods like topping or LST is enough to hit those numbers consistently.

The effects run relaxed and heady, which makes this a better evening or weekend strain than a functional daytime one. Grown indoors, environmental control during late flower will protect the terpene profile; grown outdoors, timing your harvest before heavy rain is worth the effort.

Best suited for intermediate growers who want genuine potency and aren't afraid to manage a sticky, resinous plant through trim day.

Effects & Experience

The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 60%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Blackberry Moonrocks delivers THC levels of 55-60%, 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 minutes with a balanced head-and-body experience that evolves over time.

Growing Blackberry Moonrocks

Blackberry Moonrocks 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 8-10 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 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

Blackberry Moonrocks features a fruity, earthy, floral 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, Blackberry Moonrocks 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.
