I purchased some GHS Exodus Cheese through Seedsman Seeds and it is a keeper, but my mother died before I started any more clones off her.
Just my experience, my buddy says that all seed companies put their seed in a big mixer and you get what you get. LOL
Have had good experiences with Barneys Farm and TGA genetics. Black Widow from Mr. Nice Seeds was a bust.
Actually some of the best product I have gotten is from a private breeder in Nor Cal, beautiful plants, good genetics and a very decent stone. The reason I don't use more of his stuff is it's not very good medical for my conditions.
