ChernobylStrain, Effects, Genetics, Grow Guide & Where to Buy
Few cultivars carry the cult following Chernobyl has built across the US grow community , and the genetics live up to the reputation. It is a sativa-dominant (18% indica / 82% sativa) testing at roughly 22% THC, with a flowering window of 8-10 weeks under a 12/12 photoperiod. What follows is a complete reference: terpene-led effects, genetic background, indoor and outdoor grow guidance, and the fastest way to get Chernobyl seeds shipped to your state.

ChernobylEffects & Experience
Chernobyl is best known for creative, focused, energetic. The effects come on within the first 10 minutes and settle into a stable plateau that lasts 90 minutes to two hours at typical doses. Growers and users consistently note that the high stays true to its profile rather than drifting, what you feel in the first 20 minutes is what you have for the next 90.
Growing Chernobyl
Growing Chernobyl fits indoor growers with vertical headroom; sativa stretch can double plant height after the 12/12 flip. Chernobyl is photoperiod, which means you control when it flowers by switching from 18/6 (vegetative) to 12/12 (flowering). Most indoor growers veg for 4-6 weeks before the flip. Indoor yields land around 450-550 g/m² under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce 500-700 g/plant. Expected plant height is 120-180 cm, with intermediate cultivation difficulty. Practical tips that move the needle: feed cal-mag from week 2 onward at 2-3 mL per gallon, most reverse-osmosis and soft tap water setups need it; and defoliate strategically on day 21 of flower; remove fan leaves blocking interior bud sites without stripping the plant. The most common challenge growers report is late-flower humidity if your indoor RH climbs above 55% during the final two weeks.

What is the THC content of Chernobyl?+
Chernobyl tests at approximately 22% THC when grown to its potential. Real-world numbers depend on grow conditions, harvest timing, and curing, well-grown phenotypes can land at the high end of that range, while poorly cured flower tests lower.
Is Chernobyl good for beginner growers?+
Chernobyl is rated intermediate difficulty. Photoperiod genetics give you control over plant size and harvest timing, which means a bit more responsibility for getting the schedule right. Most growers with one harvest behind them handle this strain without difficulty.
