Gorilla Glue #4 Feminized

Gorilla Glue #4 Feminized is a hybrid photoperiod plant leaning slightly indica, for growers who want heavy resin and a sour pine and fuel aroma. Expect 25 to 28% THC, a flowering window of 8 to 9 weeks (56 to 63 days) and a plant you control with the switch to 12 hours of light.

Genetics

Chem's Sister × Sour Dubb × Chocolate Diesel, a three-way cross at 60% indica and 40% sativa. Chem's Sister gives potency and a sharp chemical edge, Sour Dubb adds a sour, fuel-driven aroma, and Chocolate Diesel gives earthy depth and extra resin. Also in our catalogue: a cross with another favourite, GG4 x Zkittlez.

Aroma and effect

Caryophyllene leads, followed by myrcene, limonene and humulene: sour pine with a fuel finish, over earthy and peppery notes. The effect opens cerebral and focused, then settles into full-body relaxation within 30 to 45 minutes. CBD stays under 1%, so nothing buffers the THC.

Growing

A medium to tall plant with strong lateral branching, for tent, greenhouse or sunny garden, that flowers in 8 to 9 weeks (56 to 63 days) from the switch to 12 hours of light. Indoor yield runs 500 to 600 g/m²; outdoor plants give 600 g or more each, harvested in early to mid-October. Difficulty is moderate.

In Quebec, along the St. Lawrence, plan for the cold (see our guide to growing cannabis outdoors in Canada). The thick resin makes trimming slow and calls for steady airflow and low humidity in late flower; the trimmings are worth keeping for our guide to cannabis hash.
