From the lab panel — 22% THC, <2% CBD. From grower reports — 400g/m2 yield, citrus/sweet dominant in cured flower. moderate grow.

Smell-first, this one announces itself before the jar is even open — a sharp citrus bite that softens into something almost candy-sweet on the exhale. Chernobyl from Coastal Genetics sits at 22% THC with an 80/20 sativa-dominant split, so the effect runs clear-headed and energetic rather than couch-heavy. Coastal bred this line out of cookie/cake/runtz stock and kept the finish tight: 8–9 weeks from flip to harvest, pulling around 400 g/m² indoors when given a proper light schedule.

Plants stretch the way sativas do, so top early or be ready to manage canopy height. Mold resistance is genuinely solid here — a useful trait if your room runs humid or you're pushing an outdoor run into wetter fall weather. Difficulty lands at moderate, meaning a grower who's done a few cycles won't be caught off guard. Best suited to intermediate growers who want a fast-finishing sativa that doesn't require babysitting.

Genetics & Lineage

Chernobyl traces its genetics to 80% Sativa/20% Indica (Coastal Genetics). This sativa-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 Coastal Genetics, 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 22%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Chernobyl delivers THC levels of 22%, 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 Chernobyl

Chernobyl 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 400g/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

Chernobyl features a citrus, 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, Chernobyl 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.

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
