Quick read: 60-80% THC, 100-180cm mature height, 8-10 weeks bloom. Genetics: Guanabana (Blimburn Seeds). Difficulty: moderate.

Smell-first: cut a ripe soursop open and you're close to what this sativa fills a tent with — tropical fruit up front, then a sharp citrus bite, then diesel on the exhale. Guanabana feminized from Blimburn Seeds sits at 60–80% THC, which puts it firmly in the upper tier of potency; this is not a casual afternoon smoke for newer consumers. Indoors, the 8–10 week flower window is reasonable for a sativa, and growers pulling 400–500 g/m² have reported keeping canopy height manageable with a light LST or screen setup. Rated moderate difficulty, it handles both indoor and outdoor environments without being fussy about minor climate swings — useful for growers in regions with unpredictable shoulder seasons.

Best suited to experienced home cultivators who want a high-THC sativa and are comfortable dialling in feed schedules through a longer stretch phase.

Genetics & Lineage

Guanabana traces its genetics to Guanabana (Blimburn Seeds). This sativa-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 Blimburn 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 80%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Guanabana delivers THC levels of 60-80%, 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, starting as a cerebral buzz that gradually expands.

Growing Guanabana

Guanabana is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 8-10 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. 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 dense flower formations.

Flavor, Aroma & Terpene Profile

Guanabana features a fruity, citrus, diesel, sweet 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, Guanabana 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 Guanabana?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
