Ultimate Genetics & Terpenes Guide

Everything UK souvenir seed collectors need to know

1. Cannabis Is One Species – Four Genetic Clusters +
Basal / Ruderal – Central Asia – Autoflowering ancestor
Narrow-Leaf Hemp – Europe/China – High-CBD ancestor
Narrow-Leaf Drug – Equatorial – Classic sativa
Broad-Leaf Drug – Hindu Kush – True indica

“Sativa” and “indica” are now outdated marketing labels — they describe shape, not DNA.
2. Terpenes – The Real Flavour & Effect Drivers +
Terpenes are aromatic oils in trichomes — over 150 identified.
They shape aroma, flavour, and modify cannabinoid effects.
In 2025, breeders select for terpenes more than THC %.
3. Myrcene – The Sedative Powerhouse +
Aroma: Earthy, musky, cloves
Effect: Increases cell permeability → THC hits faster and harder
>0.5 % myrcene = classic “couch-lock” feel
Dominant in OG Kush, Blue Wizard, most indica-leaning souvenirs
4. Limonene – The Uplifting Citrus +
Aroma: Lemon, orange peel
Effect: Mood elevation, anti-anxiety, focus
Science: Increases serotonin & dopamine
Dominant in Blue Dream, Blue Lemon Haze, Super Lemon Haze
5. Pinene – The Memory & Focus Terpene +
Aroma: Pine forest, rosemary
Effect: Alertness, memory retention
Science: Blocks acetylcholinesterase — counteracts THC memory fog
Dominant in Jack Herer, Blue Dream, Durban Poison
6. Linalool – The Lavender Calm +
Aroma: Floral, lavender, candy
Effect: Deep calm, anti-anxiety, sleep aid
Science: Boosts GABA — same pathway as benzodiazepines
Dominant in Lavender, Granddaddy Purple, Frostman
7. β-Caryophyllene – The Only Cannabinoid-Like Terpene +
Aroma: Black pepper, cloves
Unique: Directly binds to CB2 receptors
Effect: Anti-inflammatory, pain relief
Dominant in GG#4, Girl Scout Cookies, most Kush lines
8. The Entourage Effect – How It Really Works +
Terpenes + cannabinoids + flavonoids work together.

• Myrcene = faster, stronger THC
• Pinene = clearer head
• Linalool = deeper calm
• Caryophyllene = inflammation relief

This is why two 25 % THC souvenir seeds can feel completely different.
9. Myrcene + Limonene – The Perfect Balanced Hybrid +
Aroma: Earthy citrus with sweet undertones
Overall feel: Happy head high + gentle body relaxation
Real examples: Wedding Cake, Gelato XL, Gorilla Zkittlez
Why it works: Myrcene adds depth, limonene adds uplift — the 50/50 hybrid sweet spot
10. Caryophyllene + Myrcene – Spicy Earth Kush +
Aroma: Pepper, cloves, deep earth
Overall feel: Heavy body stone + anti-inflammatory benefits
Real examples: OG Kush, Bubba Kush, Death Star
Bonus: Caryophyllene binds to CB2 receptors — acts like a cannabinoid
11. Pinene + Limonene – Clear-Headed Sativa +
Aroma: Pine forest with bright citrus
Overall feel: Focused, energetic, no fog
Real examples: Jack Herer, Durban Poison, Blue Dream
Why collectors love it: THC high without the mental haze
12. The Future – Designer Terpene Profiles +
By 2030, expect souvenir seeds with exact terpene recipes: pure mango, coffee, petrol, bubblegum.

Breeders are already dialling in custom profiles — the future is personalised souvenir genetics.
