Spec sheet first — strain: hybrid, seed type: autoflower, THC: 18-25%, yield band: high, environment: indoor or outdoor.

Smell-first: crack open a jar of Guava RF3 and the earthy-sweet profile hits before you even get to cultivation notes — but the grow data is what keeps growers coming back. Seedsman's Guava RF3 Auto runs 9–11 weeks seed to harvest and has been pulling 400–550g/m² in both tent and outdoor setups, which is a serious number for an autoflower. THC tests between 18–25%, so this isn't a lightweight, but it also isn't a one-hit-wonder couch-locker — expect a clear, functional ceiling for most users. Difficulty is rated easy, meaning the auto's forgiving nature handles minor feeding mistakes and light-schedule inconsistencies without punishing you hard. The flavor profile stays on the subtler side — earthy base with a sweet finish rather than anything candy-forward or loud.

Best suited for newer growers who want a high-yielding auto without babysitting a finicky plant through a long photoperiod cycle.

Guava RF3 Auto traces its genetics to Guava RF3 (Seedsman 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.

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 25%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Guava RF3 Auto delivers THC levels of 18-25%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. 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 Guava RF3 Auto

Guava RF3 Auto 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 9-11 weeks total with yields of 400-550g/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

Guava RF3 Auto 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, Guava RF3 Auto 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.
