Hybrid
4.8 (247 reviews)
GG4 came about in the 2010s, when breeders Joesy Whales and Lone Watty of GG Strains were working in Las Vegas, growing Chem’s Sister alongside Sour Dubb, and a hermaphroditic Chem’s Sister plant unexpectedly pollinated the Sour Dubb crop. Instead of tossing the resulting seeds, the pair planted them out, grew four distinct phenotypes to evaluate, and selected the fourth as the standout, which is where the name comes from.
Here’s a quick snapshot of the GG4 strain:
Type: Hybrid (roughly 63% indica, 37% sativa)
THC Range: 22%–30%
Dominant Terpenes: Caryophyllene, Limonene, and Humulene
Aroma: Heavy diesel and pine, with an earthy, chocolate-tinged depth
The strain was originally called Gorilla Glue #4 because the resin production was so extreme that it left scissors gummed together during trimming. It didn’t stick around due to trademark issues with the glue company, but people still call it either that or just Original Glue.
GG4’s Chemdawg lineage (via Chem’s Sister) is responsible for much of its diesel-forward intensity and sour edge, while Sour Dubb adds another layer of that same sour-diesel complexity along with a heavier body component. Chocolate Diesel rounds things out, contributing to the strain’s depth and resin output.
THC typically runs between 22% and 30%, putting it among the more potent hybrids, with some especially resinous cuts testing even higher. Looks-wise, GG4 is about as visually on-brand as a strain gets, with dense, chunky buds blanketed in trichomes, and sticky enough that handling the flower without it clinging to your fingers is nearly impossible.
