Probably boring Reasoning of me if Vietnamese is stemming from Thai. Please skip if want
But if we agree vietnamese is THE strongest Weed . Stronger than Thai.
And we assume the Vietnamese neded the import of Thai
There whe have two scenarios:
1: They discharged all their own vietnamese weed and just straight grew Thai. BUT why was Vietnamese then different than Thai? Probably cause it acclimatized, ok thats an explonation. but why , if their acclimatized Version was the strongest on earth , why was it not just kept? (therefore beeing simply vietnamese) probably cause it emideatly was pollinated by weaker vietnamese, ok thats an explonation, but hold on then how could we find weed in an acclimatized state (like said we assume vietnamese is stronger than thai, hence different), if threth from weak vietnamese crosspolination was existent. Probably some few Plants stay unpollinated from weak vietnamese , but sooner or later it happens to all of them, and new thai needs to be brought in… Ok thats an explonation, and the ones we rate as "most powerful " are the ones not crosspolinated yet, but already well acclimatized…
2: They interbreed Thai x Vietnamese. But why was Vietnamese then more ultimative then Thai itselve, when it consisted of weaker Vietnamese Weed x strong Thaiweed. The cross should be weaker than pure Thai itselve… Probably cause outcrossing is a Key in breeding… ok thats an explonation. but doesent 100 percent resonate with the beleve that the Landraces are inbreed… But this is anyway a generalized statement.
So, we can find explonations.
The thing is: when i hear that Vietnamese was the strongest Weed, wich i sometimes do , then i automaticall try to find out why. And those two scenarios , are hard to approve/or debunk. And i dont have to.
Its just when i hear stories about vienamese Making process, i hear so much of Hemp, forgein seeds, my initial reaction is: how is this possible.
Well your forgein-explonation is somewhat justified. And it stands on the idea that either acclimatisation to different Region is somewhat benefitial / Or that hybridisation of weaker X stronger Weed equals the strongest weed…
PS: (and i dont wanna fight wich Strain is the strongest, but thats what i feel heard, i also heard the opposite, but lean thowards …)
