The library
31 strains, four lines
Everything currently in the book. Add what you want and send the list to the breeder, and he will come back on what is actually in the tin, because runs are small and a printed list is always slightly ahead of the shelf.
Regular seeds, not feminised.
White Lightning Line
Emergen-C × Kush Mintz

What Sweettooth is
Sweettooth is a Chiang Mai based cannabis seed company specialising in exotic California genetics and small-batch quality. It sits somewhere between premium flower culture and modern street aesthetics, with a mascot you will not forget, and it is owned and run by people connected to both the Thai and the international cannabis scenes.
It is not a rack of packets by a till. The whole reason it works is that the same people run the farm an hour south, so when you ask what a cut actually does in this climate, somebody has already grown it and can tell you what happened. Ask at the counter in the shop and you will be pointed at whoever knows.
What we sell
- Small-batch drops and limited pheno runs Seeds are released in batches rather than held as endless stock. When a pheno run is done it is done, which is how a small breeder keeps quality honest.
- Crosses involving the house strain, White Lightnin White Lightnin is Sweettooth’s signature cut and the backbone of most of the in-house work. If you want to know what it throws in a cross, come and ask, because that answer changes with every run. This is the part worth making the trip for. Nobody can tell you over a website how a cross behaves through a Chiang Mai wet season.
- Imported California genetics, selected here Exotic California lines brought in and then actually grown out in this climate before anything is said about them. A lot of fashionable American genetics have exactly the wrong flower structure for northern Thailand, and we would rather find that out than you.
- Collectible packaging Designed to match the quality of the genetics inside. It is a small thing that says whether anyone cared.
How we work
- 01
Trusted genetics
Honest labelling and stable seed results. Every cut is run before it is offered, so what the packet says is what comes up.
- 02
Modern and edgy
Street culture meets horticulture. The aesthetic is deliberate and so is the packaging, because collectors keep boxes.
- 03
Potent but playful
Serious breeding, delivered without the pomposity. The mascot is a dog with a lollipop. That is on purpose.
- 04
Community driven
Active engagement across the Chiang Mai grower scene and the wider Thai and international one. Most of what gets learned here gets learned from other growers.
Picking genetics for this climate
Northern Thailand gives a grower light for free and then spends four months trying to rot the crop. Relative humidity here sits above eighty-five percent from around June to October, and a dense, tight flower in that air holds moisture until botrytis starts inside it where you cannot see.
That one fact should drive every genetics decision you make here. Open, airy structures dry out between waterings. A lot of the fashionable American cuts are exactly the wrong shape for this place, however good they look in a photograph. We would rather tell you that across a counter than sell you a packet and find out together.
There is more on all of this in the growing guide, and the farm page covers how we dry and cure what comes off it.
Before you buy
Growing cannabis in Thailand is not simply open. Depending on scale you may need to notify or hold a licence, and the requirements have shifted more than once since 2022. Work out where you stand before you plant.
And do not travel with them. Seeds count as cannabis material at a border, and the consequences are not proportionate to the size of the thing in your bag.
Common questions
What is Sweettooth Seeds?
Sweettooth Seeds, also written Sweet Tooth Genetics, is a Chiang Mai based cannabis seed company specialising in exotic California genetics and small-batch quality. It is run by the same company as The Spot dispensary on Nimman Soi 11, and its signature house strain is White Lightnin.
Are cannabis seeds legal in Thailand?
Cannabis seeds are treated differently from flower under Thai law and are not classified as a controlled herb in the same way. Cultivation is the part that is regulated: depending on scale you may need to notify or hold a licence, and those requirements have changed several times since 2022. Confirm your own position before you plant, not after.
Can I take cannabis seeds out of Thailand?
No. Carrying cannabis material of any kind, seeds included, across a Thai border is a serious criminal offence. Seeds bought in Thailand stay in Thailand.
What is White Lightnin?
White Lightnin is Sweettooth’s signature house strain and the backbone of most of its in-house breeding work. Crosses involving it make up a large part of the library.
Which cannabis genetics actually grow well in northern Thailand?
Open, airy flower structures do best, because relative humidity in Chiang Mai sits above 85 percent for roughly four months a year and dense flowers hold moisture until they rot from the inside. Dense, tight cultivars photograph well and fail here. The seed library exists so that this gets said out loud before you buy rather than after you lose a crop.
Where can I buy cannabis seeds in Chiang Mai?
Sweettooth is the seed side of the same company that runs The Spot. The full library is listed on this page. Send your picks to the breeder on WhatsApp at 061 523 7941, or ask at the counter in the shop at 36 Nimmana Haeminda Road, Lane 11, Suthep, Mueang Chiang Mai, Chiang Mai 50200, open 10:00 to 22:00 Monday to Friday, 13:00 to 23:00 Saturday and Sunday. Payment happens in person, not on the website.
How much do Sweettooth seeds cost?
Every pack is ฿800 for 5 seeds, whichever strain you pick. There are 31 strains in the library across four lines, and the price is the same across all of them.
Are Sweettooth seeds feminised?
No. Everything in the library is regular seed, so expect roughly half males and plan your selection around that. It is printed on the breeder’s own menu and it is the first thing worth knowing before you buy.
Does Sweettooth Seeds have an Instagram or Telegram?
Yes. Instagram is @sweettoothseeds.th and Telegram is t.me/Sweettoothseedscnx, and the breeder is on WhatsApp at 061 523 7941. New drops and pheno runs are announced on the feeds first, usually before they reach the library on this page.
