Quick answer

Terpenes are the aromatic compounds that give each cannabis strain its smell, and they track closely with the words people use to describe it. Myrcene reads earthy and musky, limonene reads citrus, caryophyllene reads peppery, and pinene reads like fresh pine. Strain names in Thailand usually point to genetics and lineage rather than a fixed recipe, so two batches of the same name can smell different.

Key facts

Siam Green has 5 branches across Thailand: Phrom Phong, Silom, Nana, Chinatown, and Koh Samui (Chaweng).

Key takeaways

Introduction

Cannabis came off Thailand’s narcotics list in 2022, and licensed dispensaries opened across Bangkok and the islands soon after. With that came a wall of strain names, many imported from American and European breeding programs and a few grown from older landrace lines. A lot of the names read like marketing, and some of them are. What actually sits behind the label is genetics and terpenes. This guide walks through the terpene families you will smell most often, how landrace and hybrid genetics differ, and how to read the strain names you see on a Thai dispensary shelf. Farms like Barkuna Farms grow flower that turns up in dispensaries such as Siam Green Cannabis Co.

How terpenes shape a strain

Terpenes are the aromatic oils a cannabis plant produces. They belong to the same family of compounds that make lemons smell like lemons and a pine forest smell like pine, and they do most of the work your nose registers when you open a jar. They also tend to line up with the language people reach for when they describe a strain. Here are the four you will meet most often in Bangkok.

Myrcene is the most abundant terpene in cannabis. It smells earthy and a little musky, with a ripe-fruit edge, and it shows up in mango and hops too. Strains heavy in myrcene are the ones people most often describe as relaxing.

Limonene is the citrus note. It smells like lemon or orange peel, and limonene-forward strains read bright and sharp on the nose. People tend to describe them as uplifting.

Caryophyllene is the peppery one. It is the same compound that gives black pepper its bite, so it leans spicy and warm. It is also the only common cannabis terpene that binds to the body’s cannabinoid receptors, which is part of why it draws so much research attention.

Pinene smells exactly like it sounds, fresh pine and a hint of rosemary. It is common in sativa-leaning strains and often pairs with a clear-headed, alert description.

Most strains carry several terpenes at once, and the blend is what makes one citrus strain read differently from another. That combined action, where terpenes and cannabinoids shape the experience together, is what people mean when they talk about the “entourage effect.”

Landrace versus hybrid genetics

A landrace is a strain that grew and stabilized in one part of the world without deliberate crossbreeding. Durban Poison is the textbook example, a pure sativa that developed in the Durban region of South Africa. Landrace lines tend to have tighter, more predictable profiles because they have been the same plant in the same place for generations.

Almost everything else on a modern menu is a hybrid, bred by crossing two or more parents to combine traits. Blue Cheese, for instance, comes from Blueberry crossed with Cheese, and you can pick out both parents in the smell. Hybrids are where most of the creative names come from, and they are also why one batch can vary so much from the next. Breeders and farms select different phenotypes, the individual plants that express a cross in slightly different ways, so one grower’s version of a strain can lean in a different direction from another’s.

Reading strain names in Thailand

Most strain names you see in Bangkok come from overseas breeders, and they usually nod to lineage or flavor rather than effect. Mimosa and Tropicana Cherry point at citrus parentage. Candy Crush and Tarte Tatin are named for sweet flavor profiles. Some names, like Gary Satan or Cheetah Piss, are just breeder humor and tell you nothing reliable about the plant.

The useful habit is to treat the name as a starting point, then check the genetics and the smell. The name tells you the intended lineage. The aroma in front of you tells you what the terpenes actually did in that batch. When the two line up, you have a solid read on the flower.

Here are some of the names that come up often in Thai dispensaries, with their lineage and the aromas they tend to carry:

Siam Green Cannabis Co.: from a single shop to five branches

Siam Green Cannabis Co. started as one dispensary focused on sourcing flower and looking after the people who walked in. Today it runs branches in Phrom Phong, Nana, Silom, Chinatown, and Chaweng on Koh Samui.

Siam Green works with established farms to keep a steady supply across its branches. That focus on consistent sourcing is part of how the company has grown inside Thailand’s young cannabis industry.

Ask our staff in person

Terpene profiles and genetics are easier to make sense of with the jar in front of you. Our staff at each branch can explain what a strain’s lineage means, which terpenes are driving the smell, and how two similar-sounding names actually differ. If you are still learning to read a profile, a few minutes at the counter beats any chart.

You can reach any branch directly with questions: Phrom Phong, Silom, Nana, Chinatown, and Koh Samui (Chaweng).

Conclusion

A strain name is a label for genetics, and terpenes are what you actually smell. Learn the four common terpene families, know whether you are looking at a landrace or a hybrid, and treat the name as a clue rather than a promise. Our staff can fill in the rest in person at any branch.
