What the Hell Is Alpine Guava?
James Bean here. October 2nd, 2025. Day two of our harvest season deep-dive, and today we’re talking Alpine Guava — the strain that hits like a caffeinated parrot on spring break.
Picture this: Harry Palms’ legendary Guava’z #62 had a wild night with White Nightmare, and nine weeks later, Alpine Guava popped out screaming at 25% THC. Sin City Seeds didn’t just breed a strain here — they engineered a tropical freight train.
The Genetics Game
Guava’z #62 — Handpicked by Harry Palms like a sommelier picks wine; tropical terps for days.
White Nightmare — The muscle; adds the THC wallop that turns the fruit bomb into a cerebral sledgehammer.
Together they created a hash-maker’s dream that still smokes like top-shelf flower. Built for extract heads who wash everything anyway.
Bag Appeal That Actually Matters
Dense, grape-shaped nugs dusted so heavily that it looks like fake snow. Bright green with orange hairs weaving through like tiny flavor highways. Break one open, and the terp fireworks start.
The Nose Knows
- First whiff: Tropical fruit punch with vanilla cream.
- Crack a nug: Full guava with pineapple backup dancers and a whisper of pine.
- Grind: Smoothie bar meets pine forest. Expect myrcene, limonene, and caryophyllene playing nice.
How It Hits
- T-minus 0: Vacation on the inhale, pine on the exhale.
- 5 minutes: Brain electricity — “oh shit, we’re doing this.”
- 15–45 minutes: Peak silly + focus; creativity unlocked.
- 45–120 minutes: Cruise control; energetic, functional.
- 2–3 hours: Gentle landing; no couch-lock trap.
Real Medical Value (Not Just Getting Lit)
- Depression support
- ADHD focus boost
- Migraine relief
- Nausea & appetite
At ~25% THC, anxiety-prone folks should start low and slow.
Growing This Beast
Indoor
- Flower: 9–10 weeks
- Yield: 450–550 g/m²
- Stretchy — plan training and support
Outdoor
- Harvest: early–mid October
- Yield: 600–800 g/plant (dialed-in grow)
- Prefers warm, dry (“Mediterranean”) conditions
Pro tip: Nutrient sensitive — ease into feed or enjoy crispy leaves and regrets.
Why Hash Makers Lost Their Minds
Method | Typical Yield | Notes |
---|---|---|
Ice water hash | ~4–6% full-melt | Resin heads wash clean |
Rosin | ~18–24% at 180–200°F | Tropical terp punch |
BHO | ~20–28% | Golden terp sauce potential |
When breeders design for the end game, you get Alpine Guava.
Alpine Guava vs. The Competition
- Maui Wowie: Alpine Guava outpaces and out-terps.
- Pineapple Express: Cleaner high, richer flavor; Hollywood vs. the real deal.
- Tropicana Cookies: Less sedating, more productive.
Where To Score It
- Flower: CA/CO/OR/NV dispensaries — ~$45–65 an eighth for quality runs.
- Concentrates: Live rosin ~$60–80 when the wash is on point.
The Bottom Line
Alpine Guava is modern breeding done right: 25% THC without sacrificing flavor. Perfect for mornings, creative sprints, and anyone over couch-lock.
- Great for: AM sessions, projects, flow state.
- Skip if: You’re brand new, bedtime is soon, or tolerance is tiny.
The James Bean Verdict
After 15 years at the helm of America’s longest-running seed bank and judging more cups than I can count, Alpine Guava makes the cut. Not revolutionary — just a near-perfect execution of “tropical sativa that actually works,” with extra credit for hash heads.
You won’t find this cultivar at Seeds Here Now, but we have many similar strains, including White Nightmare BX and Gelato S1. While you’re here, shop our complete collection of regular, feminized, and autoflower cannabis seeds.
