Afghani, Pakistani, Moroccan and most of the other legendary hash types were/are made with screens and it would be real hard to find seeds in those but hand rubbed would be the only technique where it would be possible. I think the hard part (with the Ingemar story) is to believe that he found both South American (Brazilian) and Indian seeds in hand rubbed hash. He used to state on his “white widow web” that very linage for the Widow. He also said he grew it with mango trees and it had a mango flavor due to that fact. He also said he grew and bred outdoors. Does mango trees do well in Holland?
I think the problem with the MrNice side of the story is that things changed. It's not that hard to see why it could but they seem to still say everything is done the “exact same way”. I have not grown the modern Black Widow so I can't say for sure but the Great White Shark and the Shark Shock won't show the same expressions in smell, flavor and high. Even the description has changed on it where it used to be Super Skunk x White Widow in the 90s and now at MrNice it's Widow x Skunk.
I had the luck of getting gifted some really old seeds in 2014 and tried to germinate them but the only one that would still grow (not frozen all those years) was this lone Great White Shark seed from Greenhouse 1997. it was very different from the Shark Shock of 2011 which I grew in 2014 along that lone GWS. There was nothing of the old Super Skunk and nothing from the old Widow in those new SS seeds. I am not saying it was not good weed but it was smooth, earthy and pretty bland to the boring side where the old seed was really loud in both smell and flavor. Acrid and rancid with huge resin heads and the effect was very akin to the old Super Skunk with a warm heavy stone. The flavor was a mix of the Super Skunk and Widow with a kind of stickiness to the smell. Nothing sweet at all. The high was also quite powerful where the new version (4 different females) were all pretty dull.
I can't really say that Shantibaba says that there were any clones before the seed version but it's a bit odd to talk about it like that though. If it was in fact from his seeds I bet he would have said so, I would. But he keeps the door open for a whole other version of Widow it seems. Hard to tell, he's not really being very specific or precise using “sort of thing” and “stuff” to yada-yada over bits of the stories he tells.
Very informative, thanks for sharing your experience.
