Critical Mass is a hybrid of Skunk #1 and an Afghani landrace cultivated by Amsterdam’s Mr. Nice Seeds.
In the 1990s, breeders Scott Blakey (aka Shatnibaba,) Neville Schoenmakers and Howard Marks (aka Mr. Nice), left Green House Seed Company to form Mr. Nice and began reworking some of the hybrids they grew there under new names. One of those strains was Big Bud, which they renamed Critical Mass.
