The shortest version: Greenhouse Seeds's take on indica genetics, 16-20% THC, 9-10 weeks total flowering, easy grow.

Lineage: Guava x Gelato 41 Auto pulls from Green House Seeds' Gelato 41 work crossed into a Guava base, then bred into autoflower form — meaning no light-schedule management required. THC sits in the 16–20% range, which is solid without being overwhelming, and the dominant notes are sweet and earthy rather than the loud citrus or fuel profiles that dominate a lot of the current auto market. Indoors, expect harvest around the 9–10 week mark from seed, with yields pushing 500–700 g/m² under decent lighting. The indica lean (roughly 70%) means plants stay compact and manageable, and the easy difficulty rating holds up — this isn't a strain that punishes minor feeding errors or humidity swings the way some Gelato cuts can.

Good pick for growers running a tent setup who want a relatively fast, forgiving auto with a calmer effect profile and enough yield to make the run worthwhile.

Genetics & Lineage

Guava x Gelato 41 Auto traces its genetics to Guava x Gelato 41 Auto (Green House Seeds genetics). This indica-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 relaxed and sleepy 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

Guava x Gelato 41 Auto 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 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing Guava x Gelato 41 Auto

Guava x Gelato 41 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 9-10 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 40-50% 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 x Gelato 41 Auto features a sweet, earthy 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 x Gelato 41 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.
