Clean, Medical-Grade Craft Cannabis Grown to GACP Standards in Bangkok
CANABANGKA is a small indoor craft cannabis farm in central Bangkok grown to GACP standards, with cleanliness as the priority. Heavy-metal results on our latest published batch sit far below the reference limits — arsenic under 0.01 ppm against a 5.0 ppm limit, lead 0.34 ppm against 10.0 ppm. A COA is available in-store for every batch we sell.
A small farm that does every step in-house
We don't grow at volume for wholesale. We run small batches in our own sealed rooms, and the people who tend the plants are the same people who trim, cure and pack them. Problems get spotted early and solved without harsh chemistry.
- Small batches, every plant individually tended
- Sealed rooms with controlled temperature, humidity and airflow
- Our own in-house nutrient formula — we know exactly what goes in
- No chemical pesticides during flowering
- Slow cure in temperature-controlled rooms, never force-dried
- Per-batch records, so every jar traces back to a grow cycle
How far below the limits — real results
Heavy-metal results for our flower against the safety limits used for reference, in ppm (parts per million). Lower is better.
| Substance | Our result | Limit | Against the limit |
|---|---|---|---|
| Arsenic | < 0.01 ppm | 5.0 ppm | ~500x below the limit |
| Cadmium | 0.06 ppm | 0.3 ppm | ~5x below the limit |
| Lead | 0.34 ppm | 10.0 ppm | ~29x below the limit |
| Mercury | < 0.1 ppm | 0.5 ppm | ~5x below the limit |
The body clears trace amounts normally when they stay under the limits. Our aim is to sit as far below those limits as we can, not merely to pass.
A “<” means the lab found nothing down to its detection threshold. These figures come from our latest published batch; results vary slightly batch to batch. Ask to see the COA for the batch on the shelf at any branch.
What “medical-grade” means here
People search for medical-grade cannabis to mean flower grown and quality-controlled to a standard fit for medical use: a controlled indoor environment, per-batch record-keeping, and lab testing confirming no contaminant exceeds its limit. We do all three. We make no claim that our cannabis treats any condition — for medical use, talk to a doctor or pharmacist.
Where the cleanliness comes from
Sealed rooms, filtered air
Grow rooms are isolated from outside air, with incoming air filtered and humidity held steady to keep mould from ever starting.
Water and nutrients we control
Our own nutrient formula, with water values measured daily, so we know precisely what the plants receive.
No chemical pesticides in flower
Pests are managed through environment control and plant-by-plant care instead of spraying.
Hand-trimmed, slow-cured
Hand trimming and a slow cure in temperature- and humidity-controlled containers, so aroma comes from the flower itself.
Lab tested
Every batch is sent for contaminant and potency testing, and the COA is kept on hand for customers.
How to read a COA yourself
- 01Check the test date and batch number match the flower you're buying
- 02Check the testing lab is an independent third party, not the seller
- 03Read the heavy-metals section (arsenic, cadmium, lead, mercury) against the limit column
- 04Check the pesticide and mould/yeast sections pass
- 05Read THC/CBD to pick a strength that suits you
- 06If a shop can't show you a COA, treat that as a warning sign
Frequently asked questions
- What is clean cannabis?
- Cannabis grown in a controlled environment with no contaminant — heavy metals, pesticides, mould — above its safety limit, backed by a lab certificate of analysis rather than a marketing claim.
- What is GACP cannabis?
- GACP stands for Good Agricultural and Collection Practices, the standard covering water source, growing medium, pest management, site hygiene, per-batch records and post-harvest handling for herbal crops. CANABANGKA grows to this standard.
- How does medical-grade cannabis differ from ordinary flower?
- In quality control. Medical-grade flower is grown in a controlled indoor system with per-batch records and lab results proving it is free of contaminants above the limits. Outdoor or resold flower often has none of that documentation.
- How far below the limits are CANABANGKA's residue levels?
- Latest published batch: arsenic under 0.01 ppm (limit 5.0), cadmium 0.06 ppm (limit 0.3), lead 0.34 ppm (limit 10.0), mercury under 0.1 ppm (limit 0.5). Every value sits clearly below its limit.
- Can I see the COA?
- Yes, for every batch. Ask at any of our three branches, or message us on LINE or WhatsApp with the strain you're interested in and we'll send it over.
- What does ppm mean?
- Parts per million — the measure of how much of a substance was detected. Safe means under the limit set for that substance, and the further under, the better.
- Is indoor cannabis really cleaner than outdoor?
- Indoor growing controls air, water, humidity and pests far more tightly, which reduces mould and environmental contamination risk. Even so, judge each batch by its lab result.
- Why choose a small farm?
- A small farm can tend each plant, catch problems early without harsh chemicals, and control trimming and curing much more closely.
- Where can I buy clean cannabis in Bangkok?
- At CANABANGKA's three branches: Phetchaburi Soi 13 (Pratunam — farm and flagship), Chinatown (Trok Sai) and Ramkhamhaeng 26/2. COAs available at all of them.
- Can I see the grow rooms?
- Yes. Our urban farm tour at Phetchaburi 13 walks you through the real grow rooms in about 45–60 minutes. Book ahead on LINE.
