Original Cali Pack by Don Merfos Exotics.

The Story

GuanaBana takes its name from the soursop fruit, the spiky tropical fruit known across Southeast Asia and Latin America for its sharp-sweet, custard-like pulp. The name suits the cross. Amnesia Haze is a Dutch coffeeshop institution, a multi-Cannabis Cup winner bred from South Asian and Jamaican landraces crossed with Haze genetics, recognised for its long, soaring cerebral effect and citrus-tropical nose. White Widow is the other parent: the 1995 High Times Cannabis Cup winner, one of the most replicated and referenced strains in European cannabis history, a resin-heavy balanced hybrid developed in the Netherlands in the early nineties. Where Amnesia Haze brings the sky-high lift and aromatic intensity, White Widow contributes structure, resin production, and a grounding quality that keeps the high from running loose.

Don Merfos Exotics selected GuanaBana from this cross for its award-winning expression: a 50-day indoor finish, full trichome coverage, and a cerebral profile that leans hard into focus and creative energy without burning out fast. The tingly onset that Amnesia Haze is known for is preserved here. The resin coat from White Widow is visible from the first look at the bud.

The Nose

Break the seal and Tropical fills the room immediately, the kind of soursop-and-citrus wave that reads more like fruit than flower. Right underneath it, Fruity comes through layered and ripe, not sharp, more like a bowl of mixed fruit in a warm room. As the nugs open up, Sweet rounds the top end while Earthy grounds the base, keeping the profile from tipping too far into candy territory. A trailing note of Herbal sits at the back, the Amnesia Haze landrace influence showing through as a slightly vegetal, green complexity that gives the nose real depth. Terpinolene drives the floral-fruity lift at the top, the terpene most responsible for that fresh, almost pine-meets-citrus character that defines Amnesia-lineage strains. Limonene adds citrus pop and lemon-peel brightness through the mid-layer. Myrcene anchors the whole profile with musky, herbal depth. Dense, well-structured buds with heavy resin coverage and a nose that shifts as the jar warms up.

The Smoke

The first draw opens with tropical and fruity across the full palate, smooth and immediate, no harshness. Sweet follows on the exhale, clean and rounded. Midway through, earthy and herbal develop as the Myrcene builds with heat, giving the mid-session a more grounded, green character that balances the fruit up top. The Terpinolene concentrates in the resin ring toward the roach, pushing that floral-fruity lift into the finish. Limonene stays bright throughout, keeping the smoke clean and citrus-forward even as the earthy notes arrive. Pale ash, even burn from start to finish.

The High

The onset is fast and precise. Focused arrives first, the kind of mental sharpening where tasks feel manageable and distractions drop away. Right alongside it, Energetic moves through the body, not a restless physical buzz but a clean motivational current that makes you want to do something with your hands or your mind. Within the first ten minutes, Euphoria and Mood Uplift land together, lifting the floor of the session so the whole experience runs at a brighter register. Creative follows as the Terpinolene settles in, opening up lateral thinking and making conversation easy. Happy runs underneath all of it, steady and warm throughout.

The tingly sensation spreads through the temples and behind the eyes early, the Amnesia Haze signature showing up exactly as expected. The White Widow genetics keep the ride structured rather than scattered, which matters at this THC level. At this potency with medium anxiety risk, experienced smokers will find this a highly functional daytime high. Pacing matters: GuanaBana is potent enough that a heavy morning session can run well into the afternoon.
