Quick read: 17-23% THC, 100-180cm mature height, 8-10 weeks bloom. Genetics: Chernobyl × Face Off OG from White Label Seeds. Difficulty: easy.

Lineage: Chernobyl × Face Off OG, two strains with very different personalities — one a sativa-leaning triband cross tracing back to Trainwreck, the other a heavy OG Kush descendant. White Label Seeds built Fallout OG around that tension, and the result is a plant that stays compact indoors (typically 70–110 cm) while still pushing 500–700g/m² in an 8–10 week flower window. THC tests cluster in the 17–23% range, which is enough to feel but not so much that newer growers lose control of the experience. The citrus and diesel on the nose lean sharp and clean; the fruity side comes through more on the exhale than the front end.

Growth behavior is forgiving — this one adapts to both indoor and outdoor setups without demanding much correction along the way. Good pick for anyone who wants a high-yielding, low-maintenance plant and doesn't have the ceiling height to run something that stretches aggressively.

Genetics & Lineage

Fallout OG traces its genetics to Chernobyl × Face Off OG from White Label Seeds. This hybrid-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 Sensi Seeds, 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 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Fallout OG delivers THC levels of 17-23%, 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 with a balanced head-and-body experience that evolves over time.

Growing Fallout OG

Fallout OG is rated as easy difficulty, making it an excellent choice for first-time growers. The plants are resilient, forgiving of common mistakes like overwatering or inconsistent feeding schedules.

Indoor Growing: Expect a flowering time of 8-10 weeks with yields of 500-700g/m². Plants typically reach 100-180cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. 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 the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Fallout OG 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, Fallout OG 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.

Who Should Grow Fallout OG?

This strain is ideal for beginner growers looking for a reliable, low-maintenance plant that delivers consistent results without advanced techniques. If you're looking for evening relaxation and deep stress relief, this is your strain.
