The shortest version: Advanced Genetics's take on hybrid genetics, 24% THC, 8-9 weeks flowering, easy grow.

Advanced Genetics lists this at $29.48 — the lowest base price in the comparison ($30.25 floor). Pack options: 3-seed at $29.48, 5-seed at $44.99, plus larger sizes.

Lineage: Chemdog x SFV OG Kush, both cuts selected by Advanced Genetics for their resin output rather than their name recognition. That pairing lands at 60% sativa structure with a firmly indica-weighted effect ceiling — 24% THC tested across multiple harvests, earthy and sweet on the exhale with no sharp chemical edge. Indoor runs average 550g/m² at the 8-to-9-week mark, which is a realistic number for a strain this potent; you're not trading yield for strength here.

Plants stay manageable in both indoor and outdoor settings, and the difficulty rating is genuinely easy — she doesn't throw tantrums over minor humidity swings or a missed feeding. Train her early if you're working with limited canopy space, since the sativa frame will stretch in the first two weeks of flower. A solid pick for newer growers who want a high-THC result without babysitting a finicky pheno.

Genetics & Lineage

Deadhead OG traces its genetics to 40% Indica/60% Sativa (Advanced Genetics). 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 Advanced 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 24%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Deadhead OG delivers THC levels of 24%, 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 Deadhead OG

Deadhead 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 8-9 weeks with yields of 550g/m2. Plants typically reach 100-160cm 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

Deadhead OG features a earthy, 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, Deadhead 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 Deadhead 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.
