The accidental cross that won three Cannabis Cups — chocolate, diesel, heavy.
GG #4 — originally Gorilla Glue #4, renamed after a 2017 trademark settlement with the actual Gorilla Glue adhesive company — came out of Las Vegas / Nevada breeder Joesy Whales and Lone Watty in the early 2010s. The lineage is Chem's Sister × Sour Dubb × Chocolate Diesel, which means it pulls from three of the heaviest diesel-leaning families in the catalog. Won three Cannabis Cup wins between 2014 and 2015 — that's what catapulted it from regional cut to national rotation. The '#4' survived the rename because that's how everyone already referred to the cut. On our shelves it's a heavy-hitter pick — popular enough to be a frequent reorder, not so popular it crowds the shelf.

Aromatic chemistry
Three layers and it walks across a room. The top is sharp diesel and pine resin, almost solvent-edged when you first crack the jar. Underneath that is dark chocolate and coffee grounds. The base is damp earth with a sour fruit note way underneath — the Sour Dubb peeking through. This is not a discreet strain.
Close, with the chocolate side stepping forward. On the inhale heavy diesel and pine — the same sharpness that hit you on the nose, but warmer. On the exhale coffee and dark chocolate come through, with a tar-pine resinous finish that sticks to the back of the throat. Burns slow. The ash is dark and oily — that's the trich-density showing.
Yes — same strain. The Gorilla Glue Co. trademark forced the rename in 2017 to Original Glue, but most Washington shops still list both. Same Joesy Whales / Lone Watty genetics either way.
Joesy Whales accidentally combined the parents and noticed the buds were so resinous they gummed up trim scissors — that's the 'Glue' name origin. The high THC plus the heavy resin is what made the strain famous, and what won it three Cannabis Cup wins between 2014 and 2015.
Heavy-hitter pick. Regulars who like Chemdawg, Sour Diesel, or Original Glue's cousins (GG #5, GG #1) rotate this in when they want the chocolate-diesel side of the family. We don't usually hand this to a first-time customer — the diesel is polarizing on the nose, and the THC runs hot enough that lower-tolerance customers can over-shoot.
GG #4 tests in the 23–28% THC range, near the top of the shelf for flower. Customers with a built tolerance handle it fine; lower-tolerance customers should go a half-dose or less the first time and see where it lands. The body weight comes on fast, even though the bud burns slow.
Most regulars reach for it after dinner, when the couch is part of the plan. The body weight comes on fast and the strain rewards slow consumption. Not a daytime strain.
Not a daytime strain. Not subtle on the nose — anyone in the same room is going to know what you opened. And not the strain to ration carefully; GG #4 burns slow but the body-weight comes on fast.
