Gorilla Glue #4 Feminized

Gorilla Glue #4 Feminized at a glance

Gorilla Glue #4 Feminized is a hybrid photoperiod plant leaning slightly indica, at 60% indica and 40% sativa, bred from Chem's Sister × Sour Dubb × Chocolate Diesel. THC is listed as high, at 25 to 28%, and the aroma is sour pine with a fuel finish. It flowers in 8 to 9 weeks (56 to 63 days).

Genetics

Three parents sit behind the plant. Chem's Sister gives potency and a sharp chemical edge, Sour Dubb adds a sour, fuel-driven aroma, and Chocolate Diesel grounds it with earthy depth and extra resin. The result is the heavy resin of a chemical, diesel ancestry, with enough sativa to keep the effect lively.

We also offer a cross of this plant with another favourite, GG4 x Zkittlez, as well as the Fast version and the Auto version of the name. This page covers the regular feminized photoperiod plant.

Aroma and effect

Sour pine with a fuel finish, over earthy and peppery notes. Caryophyllene leads the terpene profile and gives the sharp, peppery bite that defines the first impression. Myrcene adds an earthy musk that softens the chemical edge, limonene a faint citrus brightness on the exhale, and humulene rounds it out.

The effect opens cerebral and focused, then settles into full-body relaxation within 30 to 45 minutes. The onset is fairly quick for a high-THC hybrid, and with CBD under 1%, nothing buffers the THC.

Growing guide

Difficulty is moderate: Gorilla Glue #4 suits growers with at least one cycle behind them. The plant is medium to tall with strong lateral branching, and its heavy resin means more trimming and a real risk of mould in dense buds if humidity and airflow slip. It flowers in 8 to 9 weeks (56 to 63 days).

Indoors: from veg to flower

Start with one to two weeks of germination and seedling, followed by a short veg of 2 to 3 weeks, then switch to 12/12. Flowering takes 8 to 9 weeks (56 to 63 days) from the switch, a one-week window.

Plan the canopy before you flip the lights and leave room for stretch in the first weeks of flower. Topping, low-stress training or a screen of green keep the height in check and spread the tops evenly; our guide to training techniques shows how. Keep 20 to 26°C in veg.

From the fifth week of flower, keep relative humidity below 50%, with air moving above and below the canopy. The dense buds and thick trichome coat let grey mould settle fast without steady airflow.

Outdoors in Quebec

Pick a sunny, sheltered spot and plant out after the last frost. Harvest falls in early to mid-October, so along the St. Lawrence cold, wet autumn weather and early frost sit at the centre of the plan. A greenhouse helps, and seedlings started indoors in spring reach the garden with the full season ahead.

Our guide to growing cannabis outdoors in Canada and guide to late harvests in northern climates explain how to plan for the cold.

Growing tips

Train early. Topping or bending the main stem in veg opens the canopy and puts several tops at the same height. Once the buds get heavy in late flower, stakes or a screen keep the lateral branches from bending under the weight.

Give plain, pH-balanced water for the last 7 to 10 days before the cut, then judge it by the trichomes under a magnifier: mostly cloudy with a small share of amber. The heavy resin makes the trim slow work.

Dry by the golden rule of drying, 18/60/18. Hang the branches head down in a dark, ventilated room, run the dehumidifier day and night for the first 48 to 72 hours, then hold 18°C and 60% humidity until day 18. Dense, resinous tops hold water, so be patient before the jars.

Resin this heavy makes the trimmings worth keeping; our guide to cannabis hash explains what to do with them.
