Chem 4 Auto

$40.00

Chem 4 is the cut that came out of the original thirteen late, popped years after the fact when the crew got back together, which is where the Reunion name comes from. It is normally a photoperiod only proposition. Seven generations of selection is what it took to carry it into a plant that finishes in nine to ten weeks and fits in a closet.

Chem 4 “Reunion” x Short Stuff #1 (F7) | Feminized autoflower | 6 seeds | 70-80 days from seed | Born-on: Aug 2025

Parent-source credits: Chemdog.

Seed release: Greenpoint Seeds.

The Cross

Greenpoint crossed the original Chem 4 Reunion cut to a select Short Stuff #1 autoflowering plant and inbred the hybrid forward seven generations, selecting each round for the offspring that held the Chemdog traits.

The Parents

Chem 4 is one of the surviving cuts out of Greg Krzanowski’s 1991 Deer Creek bag seed, the single event most of modern American cannabis traces back to. Within that family Chem 4 is the structure and yield side: chunkier in build than its sisters and a heavier producer, which is why it ended up in more commercial rooms than the rest of them.

Short Stuff #1 provides the autoflowering trigger and the compact frame and contributes nothing else.

What’s In The Pack

Six feminized autoflower seeds, consistent after seven generations. Loud enough that concealing it is a genuine planning consideration. Large twisting colas, lime green flowers with enlarged calyxes and orange pistils.

In The Garden

70-80 days from seed. One of the easiest plants in the auto line. Hardy, quick to recover from moderate stress, and genuinely resistant to pests and disease. Short and bushy with heavy lateral branching, which suits a closet. Keep the pH stable and it handles the rest.

Seed release: Greenpoint Seeds.

    Growing nicely. Short thick stem. Planted in late April. Started slow but grew fast in the hot sun. Smells like gasoline.
