ThaiBurmese (possibly Yunnanese)
Unusual Thai land-race strain from the Burmese border region.
This is an unusual cultivar from the highlands of Northern Thailand and the nearby border regions of Burma. It may have originated through Yunnanese chinensis cultivars hybridising with narrow-leaflet Thai ganja cultivars. This is a process through which some Indochinese ganja cultivars are thought to have originated.
This strain is cultivated by various ethnic groups in this highland border region, including the Lahu, a trans-border hill tribe living in northern Thailand, northern Laos, Burma and Yunnan. Its appearance and effect are markedly different from those of the Thai-Lao ganja gene pool of the Mekong region of Northeast Thailand.
The Highland Thai strain can grow exceptionally tall, given space, potentially reaching over 4m in soil outdoors. Plants can have notably broader leaflets than typical Thai ganja cultivars. Seeds are large, also suggesting a genetic connection to Yunnanese chinensis strains.
Calyxes are large and resinous, with denser bud formation than is usual for a ganja strain. There are two main phenotypes, namely green and purple. Green types often have a musky, citrus aroma, and purple-blue phenotypes can have mango-carrot scents.
The high has been described as unique in providing a clear conscious expansion with a calm quality.
This is a rare and little seen strain that is recommended to collectors and breeders.

Photoperiod strains rely on seasonal daylight changes, so harvest timing is closely tied to your local climate.
Stage 1
Germination / Early Start
March – April
Wait for: frost risk easing, stronger spring light
Watch for: cold snaps, slow starts, excess moisture
Stage 2
Seedling / Transplant
April – May
Wait for: milder nights and settled weather
Watch for: transplant shock, wind exposure, pests
Stage 3
Vegetative Growth
June – July
Wait for: long days, regular feeding, healthy expansion
Watch for: overcrowding, nutrient issues, insect damage
Stage 4
Flowering
August – September
Wait for: shortening days, dry airflow, branch support
Watch for: mould, botrytis, high humidity, bad weather
Stage 5
Harvest
Late September – October
Wait for: ripe trichomes, dense finished flowers
Watch for: autumn rain, rot, early frosts

I ordered a pack of these and paid for original breeders packaging but still received the re-packaged seeds almost 2 months after ordering. I have had seeds repacked despite paying for original packaging but I assumed it's because there are too many packs but this time I only ordered 12 highland thai seeds so my advice is don't waste your money on original packs and if it's a must have then try different vendor.
The main issue with my order was that too many seeds were forced into the container. I had 3 highland thai completely squashed and 2 of my freebies squashed. the surviving seeds look really good but thats just unacceptable in my books. it takes quite a bit of pressure to squash healthy seeds so this was careless handling.
I hope Seedsman try to improve because they're the easiest company to shop through from my country (in terms of payment methods at checkout)

This is a TALL plant. Are you sure these aren't really Triffid seeds? It's so big we think it's eating small birds and mammals. We've got an outdoor grow in SoCal and it seems to love our climate. Our advice is nurse it under grow lights from seed to about half a foot tall and then replant in a 5 or 7 gallon container, feed it weekly and watch it grow. The live bush has a sweet, earthy aroma, without the stink of a crossbreed and won't attract anyone downwind. We get a soaring intellectual high but no paranoia. 100% germination. We grow only landrace strains and this strain is one of the reasons we switched away from crossbred plants.

5/5 germination, very healthy and vigorous plants! I made the insane decision to grow these indoors, and have kept height under control with brutal supercropping. They're now on week 13 of flower and are nowhere near finished... I had them in 2-gallon pots with organic soil, but would definitely go bigger next time to make nutrient issues a little bit less likely. They give off a distinctive carrot-citrus aroma when rubbed, and one has a pronounced bubblegum scent--looking forward to tasting these beasts!

Biggest cannabis seeds I have handled, like from some prehistoric age. They are very vigorous. Easily and quickly germinate. Once in soil, they emerge green within a couple days and are taller and leafed in no time than other strains that have been growing much longer.
Made the mistake if ground planting them at about 1-foot height. The rabits and ground squirrels decimated them overnight. Popped two more and keeping them in pots until they are 2-feet or taller.
Regular seeds, so if I do get males, will try to breed with other neglected landraces, like Sinai, Lebanese, ..., or make seeds of this one. From what I saw in the earlier vegetation, the fan leaves are probably going to be huge and might make for excellent homemade Thai stick wraps.
