Summary

• Terpenes are the aromatic compounds that give each cannabis strain its unique smell — and they shape the effect just as much as THC does.
• The ‘entourage effect’ describes how terpenes interact with cannabinoids: the same THC level produces very different experiences depending on the terpene profile.
• Myrcene = earthy, sedating. Limonene = citrus, uplifting. Caryophyllene = spicy, anti-inflammatory. Pinene = pine, alertness. Linalool = floral, calming.
• Terpenes are volatile — heat, UV, and poor drying destroy them. Slow drying and a proper cure of 4–8 weeks preserves them.
• Choosing seeds by terpene family (citrus, earthy, floral, fuel) is a more reliable guide to effect than choosing by THC percentage.

The Chemistry of Cannabis Aroma

Close your eyes and think about the best cannabis you ever smelled. That explosion of citrus, pine, fuel, berries, or earth, that is terpenes. Not THC, not CBD. Terpenes are aromatic compounds produced in the trichomes of the cannabis plant, also foundthroughout nature: limonene in lemon peel, linalool in lavender, pinene in pine needles.

Why Terpenes Matter More Than THC

For decades, potency was measured almost exclusively in THC percentage, always an oversimplification. The ‘entourage effect’ describes how terpenes interact with cannabinoids to modulate the experience. Two strains with identical THC levels can produce completely different effects depending on their terpene profile.

The Key Cannabis Terpenes

Myrcene: Earthy, Musky, Sedating
The most common terpene in cannabis. Associated with the body-heavy, relaxing effect of indica-dominant strains. Also found in hops and mangoes. High-myrcene strains tend toward physical sedation.
Limonene: Citrus, Uplifting, Mood-Enhancing
Found in lemon and orange peel. Associated with elevated mood and stress relief. Common in Lemon Haze, Tangie, and citrus-forward varieties. Produces energetic, daytime-friendly effects.
Caryophyllene: Spicy, Peppery, Anti-Inflammatory
The only terpene known to interact directly with cannabinoid receptors (CB2). Associated with anti-inflammatory properties. Found in black pepper and cloves. Common in Kush varieties and Cookies-family strains.
Pinene: Pine, Fresh, Alertness
The most common terpene in nature. Associated with alertness and memory retention, and may counteract some short-term memory effects of THC. Found in Jack Herer and Blue Dream.
Linalool: Floral, Lavender, Calming
The dominant terpene in lavender. Associated with calming and anti-anxiety effects. Found in many Kush varieties. Particularly interesting for stress and sleep applications.

Terpene Preservation: Why Curing Matters

Terpenes are volatile. They evaporate with heat, UV, and poor handling. A badly dried bud always disappoints regardless of genetics.
Best practice: slow dry at 18–22°C, 45–55% humidity for 10–14 days, then cure in sealed jars for 4–8 weeks, burping daily for the first two weeks.

Choosing Seeds by Terpene Profile

At Jonny Seeds’, strains are organised by flavour family: Fruit Flavors, Terpene Safari (rare and unique terps), and Colour Garden. These categories help you navigate by what matters, not just THC numbers. Citrus-forward and energetic? Look for limonene-dominant strains. Deep earthy relaxation? Myrcene-heavy varieties.
