GG4

Also known as: Gorilla Glue #4, Original Glue, GG#4

Breeder: Joesy Whales & Mardogg (GG Strains LLC)

GG4 is renowned for extreme resin production, pungent diesel-chocolate aromatics, and heavy-hitting potency. Created accidentally through a hermaphrodite pollination event, it became one of the most awarded strains of the 2010s. High Times named it 'the most powerful strain on Earth' in 2014. Both co-creators have since passed: Joesy Whales died in 2020 and Lone Watty in 2021.

Lineage & Genetics

Cross: (Sour Dubb x Chem's Sister) x Chocolate Diesel

Chem's Sister is a sativa-leaning Chemdawg phenotype. Sour Dubb is believed to descend from East Coast Sour Diesel and Sour Bubble. Chocolate Diesel is a cross of Sour Diesel and Chocolate Thai, adding the mocha/chocolate undertones that distinguish GG4 from other diesel-forward strains.

Environment
Dry Mediterranean or controlled indoor. Humidity below 50% RH in flower.

Grow Tips: Stretches aggressively — expect 50–100% height increase after flip. Branch support is non-negotiable in late flower. Heavy feeder, especially Cal-Mag in early flowering. Carbon filtration is a must — extremely strong smell from week 4. The Chem's Sister parentage carries some hermaphrodite potential under stress.

History & Origin

Born from an accident in Nevada around 2008–2010. Joesy Whales was growing Chem's Sister alongside Sour Dubb when a hermaphrodite pollinated the crop. He discarded the seeds, but friend Mardogg kept a handful. Years later, Mardogg popped six seeds — four females emerged, all stable. Phenotype #4 was the standout. The name was an inside joke about resin gluing their scissors shut. In 2017, a trademark lawsuit from the Gorilla Glue adhesive company led to the official rename 'Original Glue.'
