Quick read: 20-25% THC, 100-180cm mature height, 8-10 weeks bloom. Genetics: Green Crack x Core (Blimburn Seeds). Difficulty: moderate.

Smell-first: crack open a cured jar of this Blimburn cross and the citrus-diesel wave hits before you've even looked at the bud. That aromatic profile carries straight through to the effect — a clear-headed, energetic high sitting somewhere in the 20–25% THC range, without much CBD to soften the edges. Grown indoors, expect 400–500g/m² after an 8–10 week flower run, which is a solid return for a sativa-leaning plant that doesn't require expert-level dialling. It handles both indoor and outdoor environments without complaint, though outdoor growers in shorter Canadian seasons should plan their timing carefully — finishing dates in late September suit most of BC and Ontario if you're starting early enough.

Green Crack's upward-driving genetics push growth through stretch, so topping early keeps canopy management practical for moderate growers. Best suited to someone who wants a productive, alert-effect sativa without babysitting a finicky pheno.

THC Level & Potency

Green Crack x Core delivers THC levels of 20-25%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes, starting as a cerebral buzz that gradually expands.

Growing Green Crack x Core

Green Crack x Core 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

Green Crack x Core features a fruity, citrus, diesel, skunky 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, Green Crack x Core 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.
