Why this one matters: hybrid genetics with a 16-20% THC ceiling and earthy/sweet-led terps. 9-10 weeks total flowering, indoor or outdoor.

Greenhouse Seeds lists this at $19.44 — the upper end of the comparison range (up to $11.23). Pack options: 3-seed at $19.44, 5-seed at $31.10, plus larger sizes.

Lineage: Green-O-Matic × Big Bang Auto, both Green House Seeds originals, gives Auto-Bomb a genetic foundation built for speed and output rather than complexity. At 16–20% THC, the effect lands on the heavier, body-focused end of the spectrum — the kind of stone that settles in the shoulders and stays there. Yields in the 500–700 g/m² range are unusually strong for an autoflower, and the 9–10 week seed-to-harvest window means you can run multiple cycles in a single season outdoors or stack rotations under lights without much downtime. The flavor profile skews earthy with a quiet sweetness underneath — nothing flashy, just clean smoke.

Difficulty is genuinely low: no complicated training required, tolerates minor feeding mistakes, and performs in both indoor and outdoor setups without fussing over the environment. Best suited for newer growers who want a high-yielding auto without a steep learning curve, or experienced growers looking to fill a fast production slot.

Genetics & Lineage

Auto-Bomb traces its genetics to Auto-Bomb (Green House Seeds genetics). This hybrid-dominant autoflower seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Greenhouse Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily euphoric and relaxed 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 20%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Auto-Bomb delivers THC levels of 16-20%, 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 Auto-Bomb

Auto-Bomb 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 9-10 weeks total with yields of 500-700g/m2. Plants typically reach 60-120cm 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

Auto-Bomb 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, Auto-Bomb 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 Auto-Bomb?

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.
