here's a clone of a clone story for ya
i got permafrost from a friend who got it from the breeder (TWxsuperdank)
he said he cloned it for about 10 generations
i got it and cloned it for another 5-6 generations
we both kept monthers, but when they get too big we flowered them and started a new mother (here in oregon a 12" plant in veg is considered mature by OMMP and part of your 6 flowering, sometimes putting you over the limit)
so anyway, i gave a clone back to the friend....he gave it back to the breeder, and the breeder said it was better than the origional he had and decided to scrap his and keep going with mine. dont know what he thought was better. something must have changed or gotten better.
