Hey Dicko,
Ive never had any Mongolian seed, but I still may have some giant Russian. When I was chasing giant pumpkin stock I had some other genetics gifted as well.
I did give some away, but I'm sure it wasn't all of them. They do the throw multiple heads, not a singular huge head. These are tall as F, with a dominant head and a few lateral flowers.
If I've got some, your welcome to them
If you get onto the mongolians and get a head set in seed I'd like to put my hand up bro.
