Best cannabis farms in Thailand (2025)
Growing cannabis is equal parts science and art. The right balance of light, nutrients, and care makes the difference between a forgettable flower and something that is truly medical-grade. And while there are a lot of great cannabis farms in Thailand, finding the one that offers quality and consistency is no easy feat.
Below, we’ve rounded up five cannabis farms in Thailand that are growing top-tier buds, so you don’t have to sift through the so-so to find the spectacular.
5 Best cannabis farms in Thailand
1. RGT Cannabis Farm
Opening hours: Daily, 9.30 am to 5pm
Location: RGT Cannabis Farm, 256 Moo 18, Baan Nong Phueng Soi 4, Inthakhin, Mae Taeng, Chiang Mai 50150

If you’re looking for a cannabis farm in Thailand that specialises in medical-grade cultivation, RGT Cannabis Farm (The Right Global Trading Co., Ltd) should be on your radar.
As one of the few farms certified by the world renown certifying company SGS for Good Agricultural and Collecting Practices (GACP) for the The Medical Cannabis Industry, RGT Cannabis Farm operates at the highest level. This means that every bud that leaves their facility is pharmaceutical-grade, meticulously grown, and entirely free from questionable pesticides and chemicals.
Their secret is the aeroponics cultivation method. Instead of soil, RGT’s cannabis thrives in a high-tech misting system that delivers nutrients straight to the roots. The result is pure, potent strains.
You’re welcome to tour the facility in Chiang Mai and see the process up close (visits are by appointment only). But since they’re serious about their quality control, you have to suit up in a hairnet and protective gear. Yes, it can feel like entering a biotech lab rather than a growhouse, but that’s exactly the point.
Once inside, you’ll see rows of lush, carefully nurtured plants thriving in a humidity-controlled environment. You can also get a glimpse at the rigorous testing each batch undergoes before hitting the market. And if you love that unmistakable fresh bud aroma, well, you’re in for a treat.
The team is just as impressive as the facility. Passionate and knowledgeable, they’re happy to walk you through the process, answer questions, and share insights into what makes their cannabis so high-quality.
2. Medicana
Location: Medicana, 1679/2 Ladphrao 94, Phlabphla, Wang Thonglang, Bangkok 10310

Opened for the first time in 2022, Medicana was the first licensed indoor cannabis facility in Bangkok. Ever since then, they’ve gone to establish a major presence in Thailand’s cannabis industry.
From day one, their focus has been clear: to deliver medical-grade cannabis cultivated with precision, backed by science, and free from the inconsistencies you’ll find elsewhere. And so far, they’ve made good on that promise.

Inside their indoor cannabis facility in Bangkok, it’s all about control. Over 80 cultivation units nurture more than 2,000 plants in an optimised environment, with smart farming systems, automated fertigation, and a genetics program designed to refine and enhance each strain. The goal is absolute consistency. Every batch meets strict FDA standards, is COA tested, terpene profiled, and is completely free from heavy metals or contaminants.
Medicana is perhaps best known for their high-CBD, high-THC medical strains. If you’ve been exploring Thailand’s cannabis scene, you might recognise their signature cultivars. Gastropop, Motor Breath, Pineapple Express, Dosidos, and Banana Punch? That’s Medicana.
In addition to the premium cultivars, Medicana also supplies pre-sorted cannabis clones. Available in Rockwool and in volumes from 100 to 1,000 plants, these clones give growers a head start with genetically identical, high-performing cuttings taken from carefully selected mother plants.
3. Sticky Hands Laboratory

There aren’t a lot of cannabis farms in Thailand that boast the same hands-on approach and dedication as Sticky Hands Laboratory. More than a farm, this high-tech cultivation lab produces some of the most sought-after strains in the country with a firm grip on quality control, genetic refinement, and climate mastery.
Using AutoClimate, a smart environmental system that controls temperature, humidity, and airflow, Sticky Hands Laboratory makes sure every plant gets the perfect growing conditions. This allows them to cultivate bigger, healthier buds and stronger flavours every time. And they don’t just grow for the sake of it. They lab-test every strain, so whatever you’re getting from their farm is the highest quality.

Their lineup reads like a connoisseur’s dream. Panna Cotta (a Wedding Cake x Sundae Driver cross) is a favourite for its smooth smoke and rich terpene profile. Not to be outdone, their Diesel (Mexican Sativa x Afghani) brings back that nostalgic ‘90s sharp-sweet gas. And if you’re after something to fully switch off, Strawberry Marshmallow OG wraps floral, earthy flavours.
Sticky Hands Laboratory’s quality has also taken trophies. Their Slapz strain recently took 1st place at Full Moon Sesh’s Hash Holes. A mix of Runtz and Grease Monkey, it hits fast and hard with a deep, gassy aroma that stays with you.
4. Iridescent Med
Opening hours: Daily, 9am to 5pm
Location: Iridescent Med Company Limited (Head Office) 407/39, Samrong Nuea Subdistrict, Mueang Samut Prakan District, Samut Prakan 10270
Contact information: Website | Instagram | LINE
Iridescent Med is another fantastic cannabis farm in Thailand with two large-scale cultivation sites (also double as factories). Both follow GACP standards guidelines for high-quality production.
The larger facility in Chon Buri spans an impressive 20,000 square metres. It churns out up to 16 metric tons of medical cannabis flowers annually. The farm stands out for its eco-friendly process, using only clean energy and leftover heat to cut down on waste. Their Bang Pu factory, though smaller at 1,500 square metres, specialises in rare cannabinoids for medical use and produces over a metric ton of medical-grade flowers each year.

Iridescent Med’s rigorous pheno hunting allows them to cultivate distinct strains that are uniquely their own. Some of their notable strains include Sugar Cane, Compound Z, Hybrid, Apple Banana, and Nuke THC, which can be found in dispensaries across Thailand.
For those in Bangkok, Iridescent Med also operates a dispensary in Ekkamai. Here, you can sample their goods before deciding to go all in.
5. Tropical Thunder

Having spent years perfecting a cultivation method that prioritises balance, sustainability, and flavour, Tropical Thunder grows their top-quality cannabis the natural way.
Instead of using artificial fertilisers, they focus on living soil, where worms, fungi, and microbes break down organic matter to create rich, nutrient-packed earth. This slow, natural process helps their plants grow strong and healthy, keeping the soil full of life for future harvests.
Unlike the quick-fix approach of synthetic fertilisers, Tropical Thunder relies on organic amendments like alfalfa meal, feather meal, and rock phosphate, which gradually release nutrients as microbes decompose them. It’s a patient approach, but it leads to healthier, more flavourful buds.

And the results speak for themselves. Their award-winning Miami Mami strain (a zesty, fuel-tinged hybrid) clinched first place at the Budtender Cup 2024. Plus, they also secured second place at The Phuket Cannabis Cup #3 for The Open Category.
Their farm may be smaller than some, but they make every space count. With beds on wheels, they can move plants around easily to make sure each one gets the best conditions to thrive. With big plans ahead, they’re proving that when it comes to cannabis farms in Thailand, small scale doesn’t mean small impact.
We’re sure there are numerous other cannabis farms in Thailand offering high-quality products, but if you’re looking for reliable options, these five are a great place to start.
