Strain Overview
Alpine Guava is the Sin City Seeds release that finally pushed real guava terps into the mainstream menu. The cross is Guava’Z #62 on the female side and White Nightmare on the male, and the result is a sativa-leaning tropical fruit bomb that smells like guava juice with a vanilla cream chaser the second you open the jar. The Guava’Z mom does most of the heavy lifting on flavor. The White Nightmare dad layers in resin, structure, and the kind of stretch that turns a 4×4 into an under-canopy management problem if you sleep on training.
She is loud. Not loud in the gas-funk OG sense, loud in the candy-tropical sense that makes a room smell like a fruit stand. The flower throws long, foxtailing colas with a frost layer that the White Nightmare side is known for, and the cured nug has the kind of bag appeal that sells itself. Most batches test in the 22 to 28 percent THC range with terpene loads above 2 percent, and the dominant note is loud guava with a tropical-fruit-punch backdrop.
She is a sativa-leaning hybrid that hits cleanly. Bright on the front, settled in the back, with a long social run that fits the daytime side of the menu better than the evening. If you are running a tropical-leaning lineup, she is the one to anchor it.

Lineage & History: The Vegas Tropical
Sin City Seeds came out of the Vegas medical scene with a small catalog of heavy-hitters. Blue Power, White Nightmare, and a deep work in tropical and gas crosses gave them a reputation for clean genetics and reliable phenos. White Nightmare in particular became a cornerstone of their breeding program, a White-leaning indica that throws elite resin output and lends itself to crosses that need a frost backbone.
Guava’Z #62 is the other half. The Z is Zkittlez, the Guava lineage trace runs through the modern fruit-forward Cookies-family hunts, and the #62 designation is the keeper from the hunt that locked the guava expression. She is sweet, tropical, and resin-heavy on her own, the kind of mother that imparts her dominant terpene profile across most phenos in any cross she is run through.
Crossing the two was a deliberate move toward extract-grade flower. Sin City has been clear that the goal of the project was to combine elite terpene expression with the kind of resin output that produces reliable solventless and hydrocarbon yields. They landed it. The Alpine Guava cut that GSRH carries throws guava-loud terps with the resin volume that makes her a real extract candidate, not just a flavor-only flower run.
The cut you get here is the verified Sin City work, cloned forward from a tested mother and HLVd-screened before shipment. Bag appeal is loud, structural reliability is solid, and the terps run as advertised.
Flavor & Aroma
Crack a jar and the guava hits first. Sweet, tropical, almost juice-like, with a vanilla cream layer underneath that softens the front and makes the profile more complex than a one-note candy strain. There is a faint pine snap in the back from the terpinolene, and a slight floral lift that ties the whole bouquet together. Some phenos lean harder toward pineapple, others stay closer to pure guava, the dominant impression is always tropical fruit with a creamy back.
On the inhale she opens with sweet guava and tropical fruit punch. Mid-palate the cream rolls in, vanilla, soft, with a faint citrus pop from the limonene. Exhale finishes round, sweet, with a long tropical fade that hangs on the tongue. Smoke is medium-bodied, smooth, easier on the throat than most modern fuel-leaning hybrids. The flavor on the cured flower carries cleanly into both rosin and live resin, and the rosin in particular pulls the cream side hardest.
She presses to rosin elite. The Sin City notes about extract-grade output hold up in real-world washes. Yields are competitive with any modern fruit-forward hybrid, and the terp retention through the press is loud.
Effects & What to Expect
Onset is fast. Within five minutes the cerebral lift starts, bright, mood-forward, with a clear sociability that pulls focus outward. The first thirty minutes are the sativa-dominant part of the run, talkative, energetic, music-engaged, with no racy edge that pushes toward anxious territory. She is a clean uplift, not a hard sativa wire.
The mid-section settles. By an hour in the cerebral side has softened to a warm focus, and a light body load lands without pulling toward the couch. Most phenos hold the head-forward character through the second hour. Total run time is two to two and a half hours, with the fade gentle and the come-down clean.
Daytime, mid-afternoon, social fit. She is a working strain that pairs well with conversation, light tasks, and outdoor time. New users should still respect the THC number, but the head-forward character makes her one of the more comfortable high-THC sativas in the modern menu.
Growing Alpine Guava
She is intermediate. Vigorous in veg, tall in stretch, and responsive to aggressive training. If you have grown a Zkittlez cross or any sativa-leaning Cookies hybrid, she will feel familiar.
Stretch on the flip is significant. Expect 2x to 2.5x, sometimes more with sativa-leaning phenos. Top her early and often, lollipop the bottom third before flip, and run a screen if you are working in a smaller tent. Branching is strong but lanky, the lateral colas develop long and need support, and a 4×4 fits four plants in 3-gallon pots comfortably without crowding. Indoor flowering finishes 50 to 65 days, with most phenos cutting around day 56 to 60. Outdoor harvest lands late September to early October in dry-fall climates.
Feed her medium intensity. Around 850 to 1000 ppm in peak flower works well. She rewards a strong calcium-magnesium program through stretch and prefers a slightly cooler night drop in late flower to push resin coverage. Watch the canopy, the long colas can foxtail under hot light if you run too close, give her two to three feet of headroom from the canopy to the lamp. Humidity discipline matters in late flower, drop RH to 45 percent for the last two weeks because the long colas can hold moisture in the inner stack.
She is a clone, not a seed run, so what you see is what the mother produces. The cut from Sin City throws consistent guava-loud expression, and the GSRH cut is HLVd-screened before shipment. She arrives rooted and ready to plant the day it lands at your door.

Loud. The guava-tropical front is unmistakable past week three of flower, and the smell will fill a small grow space within minutes of opening the door. Carbon filter is required.
