    The Golden Trifecta: Potent, Fast, And Bountiful

    The original strain that was created by Critical Mass Collective Seeds was Monster Mass - the re-worked variation of Critical Mass. The result was an unbelievably fast-flowering strain that packed a wallop and produced flowers like no other.

    Monster Mass made waves, and, with a 45-day flowering time, it turned heads. The cherry on top was that Monster Mass was also capable of producing 800g/㎡ of ultra-potent flowers. This was just the tip of the iceberg, as Monster Mass became the base for creating a handful of exciting hybrids.

    When you look at Critical Mass Collective Seeds’ offerings, you will be genuinely impressed by each strain's ability to flower within 50-days. Additionally, the yields are monster and the potency is sky-high. Take a look at their incredible selection, such as Moonshine Mass, Super Mutant Mass, and Psychotropic Mass.

    Improving The Golden Trifecta With The Autoflowering Trait

    You read that right - Critical Mass Collective Seeds offers their regular seeds in autoflowering form. These already incredible strains are made even better by having autoflowering genetics injected into them.

    Prepare for the fastest flowering cannabis strains that pack everything you could ever want when you choose Critical Mass Collective Seeds.
