Chem Dog #4 brings lemon-cleaner sharpness, pine, and fuel to a family reunion that never learned to keep the smell down. This indica-leaning selection belongs to the original Chemdog seed family, with a history rooted in Grateful Dead parking-lot lore and a reputation that goes well beyond the backstory.
The accepted account traces that seed stash to flower purchased through Joe Brand and P-Bud in 1991. Chemdog germinated seeds from it over several years, then gave Joe four remaining seeds in 2006. Joe selected plant #4 as the closest match to the original flower and called it the Reunion Pheno. Its exact parents remain unknown. The reunion has a story; the ancestry still has a blank space.
Pungent citrus leads the nose, with sweet earth and pine underneath. The flavor follows through with a fuel edge that hangs around after the brighter notes fade. There’s enough sweetness to round the corners, but the Chem character keeps its work boots on.
Flowers are commonly described as substantial and resinous, giving the sharp aroma a suitably frosted delivery system. Color and density vary with the grow, while that citrus-and-chemical profile remains the more useful calling card.
Longtime fans describe a euphoric lift followed by pronounced physical relaxation, sometimes with a creative streak before the heavier calm settles in. The mood can brighten while the motivation to get up becomes negotiable. An indica lean doesn’t erase the head high; it gives it somewhere comfortable to land.
The original Chem Dog #4 is a clone-only selection. Seeds sold under the name represent reproductions or breeding work rather than the original plant itself, so provenance matters when the goal is that specific cut.
Published flowering estimates vary from roughly nine to eleven weeks, with Weedmaps listing 70–77 days indoors and a late-October outdoor finish in suitable Northern Hemisphere conditions. Treat those dates as planning estimates, with the particular cut and growing environment determining the finish.
Its substantial flowers make branch support and airflow practical considerations during bloom. Outdoor growers need a season that can carry those buds through autumn. The reunion is worth planning for; the harvest calendar shouldn’t be a surprise guest.
