My pack of Project 4516 x Apple Mintz popped 12/12, very healthy and vigorous. I have some other 4516 crosses as well and all of them popped out mostly purple, I would say she is a very consistent parent so far.
The market will put out what customers are willing to buy, just because someone did not work on a strain for a decade does not mean they make trash beans. Honestly look at all the euro breeders who have been working the same strains for 20 years, no one wants that shit. Mr. Nice is probably the best breeder alive but is his shit popular? Some of his sativa work is but it is the same old same old that is better when crossed with "hyped" strains, looking at you Ghost Train Haze.
