GG4 is another Gorilla Glue phenotype that was first bred by GG Strains and was formerly called Gorilla Glue #4. This is a sister strain to GG1 and takes its genetics from parent strains Sour Dubb, Chocolate Diesel, and Chem’s Sister. This strain has won top billing at various Cannabis Cup events in Michigan, Los Angeles, and even Jamaica. GG4 grows very tall, so it may be a good choice only for growers who have plenty of head space. Effects of GG4 include a sense of blissful transcendence, full body relaxation, and significant mood boosts.
