Part of the Smash Hits Cannabis line from the pioneering Chemdog line created by Greg “Chem Dog” Krzanowski, Chem S1 is among the clones produced. This strain from the legendary director of cultivation at Canna Provisions comes bred from a single Chem D seed from a male flower, giving Chem S1 cannabis its unique characteristics as a stronger, more impactful experience. Again, this strain is known for its potency, so be warned.
