I swear these type of threads pop up every couple weeks. There was one complaining about the lack of Thai strains a couple weeks ago.
It's funny how the guy says, I know about Ace's strains I'd like something different. But still everyone chimes in, Cannabiogen and Ace immediately. What a bunch of stoners. And it shows how Ace owns the sativa specialty market.
It's inevitable that these strains are rare, even in a sane world without global trade and law enforcement forcing people to grow short flowering strains most people would go for stuff that takes 24 weeks to finish.
It doesn't help that most growers in equatorial zones probably don't have access to the internet or market seeds globally. These areas tend to be undeveloped with terrible economies. I'm sure there's dudes in central Africa, Columbia, Brazil, Kerala, SE Asia, who'd love to sell some seeds. Only way to get them is to go there.
I understand that shorter flowering strains have made their way into many of these areas but I'm guessing the closer you get to the equator the more useless they become. Most strains would autoflower. Get a foot high and no higher.
The equator is so humid, once they auto flowered they'd immediately rot. Equatorial strains have that loose leafy structure for a reason.
To me it's questionable why someone at the equator would want a strain from somewhere else, except to make hybrids. And why someone far from the equator would want an equatorial strain except as a novelty.
That said I understand why you want the real 24 week strains and not the shorter flowering re-creations and hybrids offered by the popular companies online. For the reasons above these strains are great-I would have never grown Thai or Malawi if it wasn't for a tamed, 12 week version someone took a lot of time and energy to breed and develop.
But it's not the same thing as a true unpredictable, possibly hermaphroditic, 20 weeks plus flowering landrace. The Real Seed company usually has a couple, the dude above who mentions French Touch seeds, old Gypsy stuff, Derg Cora collective may be heading you in the right direction.
I know if you dig you may find some more. Snow High Seeds is overpriced but they have some long flowering stuff. They have a Panama Red x Congolese listed at 16-24 weeks flowering. For $198! Holy shit that's awful. Pay to play I guess.
Vietnamese Laughing Grass, Lambsbread Haze..Holy fuck $198 for the LambHaze and I look closer and it's only 5 seeds!! I was about to say why don't people talk more about this company, I'm curious if they're good or bad. But damn they better be fucking good or else they're crazy scammers. Almost have to be good at those prices.
But there is stuff out there is you know where to look. The website ********** has a huge database of seed companies. Do a search for there for Thai or whatever and you'll be headed in the right direction.
