I used TPD a lot three years ago and was not impressed with 99.9% of them, however second genaration seedlings were somewhat better but not great. I found that a seedling from TPD works a lot better than TPD for me. I used Martin Blondell last year (kid from TPD) and got the big eyes I expected to get three years ago. Almost every seedling from MB had huge eyes. This is one useing MB as the pollen parent
This is one useing it as the pod parent.
I have several seedlings both ways that I will move to the hybridizing area later in the year.
