Gorilla Glue x Girl Scout Cookies strain at a glance

What is the Gorilla Glue x Girl Scout Cookies strain?

Gorilla Glue x Girl Scout Cookies is an original QCS strain: Quebec Cannabis Seeds is its original breeder, and this is one of our own crosses, bred in Quebec since 2015 by a grower with more than 35 years of experience.

This strain is a feminized cross of Gorilla Glue and Girl Scout Cookies, two of the best-known names in modern cannabis. Gorilla Glue, often shortened to GG4, is famous for its sticky, resin-covered flowers and strong, pungent diesel-and-earth character. Girl Scout Cookies, or GSC, is the sweet, baked-goods hybrid that helped start the whole dessert-strain wave. Crossing them is a natural move, and QCS did it to combine the resin and vigour of the first with the sweet, doughy flavour of the second.

Because both parents are popular, a lot of seed companies sell something with a similar name, and each uses its own breeding. You will also find strains with names like Gorilla Cookies on the web. Lineages, THC figures and flowering times you read elsewhere may differ from ours. The numbers on this page are for the QCS version only.

Is Gorilla Glue x Girl Scout Cookies indica or sativa?

QCS lists this cross as 60% sativa and 40% indica, which makes it a balanced hybrid that leans a little toward sativa. In the garden that tends to mean a medium-height plant with some stretch after the flip, rather than the short, squat frame of a pure indica. The product page says it benefits from one topping and a net indoors, which is the usual way to keep a stretchy hybrid even.

The page also mentions good resistance to many common pests and diseases, and dense, resinous flowers. If you are not sure which side of the spectrum you prefer, our guide to what indica does to you is a helpful contrast to a sativa-leaning hybrid like this one.

Smell and flavour: earthy, creamy vanilla and diesel

QCS lists the taste as earthy, cream and vanilla, baked dessert and diesel. That is a lovely mix of the two parents. The earth and diesel come from the Gorilla Glue side, and the cream, vanilla and baked sweetness from the cookie side. Growers commonly report that both parents give a pungent, room-filling smell in late flower, so plan carbon filtration if you grow indoors or have neighbours close by.

Terpene expression, as always, depends on your light, temperature, drying and curing. Many growers of GG-type plants note that caryophyllene, the peppery terpene, often shows up strongly in these lines, which fits the earthy, slightly spicy base. A slow dry and a month in jars will bring the sweet notes forward.

Gorilla Glue x Girl Scout Cookies effects

QCS describes the high as uplifting, creative and euphoric, with a body effect that settles in after about half an hour. The page's own FAQ calls it strong but not overwhelming. That matches what consumers commonly report from both parents: an energetic, happy start followed by physical relaxation, with the body portion arriving a little later.

Effects vary by person and dose. Dry mouth and dry eyes are the most commonly reported downsides for GG and GSC type strains, and some consumers report anxiety at high doses. Start low and go slowly, especially if you have not tried a Gorilla Glue relative before, because those lines have a reputation for being sticky and heavy-hitting.

How strong is Gorilla Glue x Girl Scout Cookies? THC content

QCS lists this cross at 20% THC with low CBD, under 2%. You may see higher numbers quoted for Gorilla Glue on the web, where lab results often land in the mid-to-high twenties for the original cut. Other seed companies' versions may differ; the figures here are for the QCS version, taken from our own grows. In practice, 20% is a respectable, moderately strong figure that many people find easier to enjoy than the extreme end. If you want something stronger, see our seeds over 25% THC.

Growing Gorilla Glue x Girl Scout Cookies: flowering time and yield

Indoors, expect 55 to 65 days of flowering (about 8 to 9 weeks) and a yield of up to 550 g/m². Outdoors it is usually ready in early October, with 600 to 700 g per plant possible. QCS rates it beginner-friendly, easy to grow even for a first-timer.

Practical tips from the product page and from common experience with both parents: top once and use a net to even out the canopy, keep the plant on the moderate side of feeding, and give it good airflow, because dense, resinous flowers in the last weeks can trap moisture. Harvest by checking trichomes with a loupe rather than counting days, and cure patiently. Gorilla Glue relatives are known for sticky trim, so keep your scissors clean.

What customers report

This cross does not have any customer reviews on our site yet, so we will not invent any. What we can tell you is that the specs on this page come from QCS's own grows, not from customer reports. If you grow it, we would love to hear how it goes, and a review helps the next grower.

In the meantime, the web is full of feedback on both parents. Growers of Gorilla Glue and Girl Scout Cookies lines commonly report heavy resin production, strong smells and vigorous growth, with the occasional complaint about sticky trimming and pungent odour. Those are useful clues for planning your own grow.

Is Gorilla Glue x Girl Scout Cookies right for you?

Choose this cross if you want a balanced, slightly sativa-leaning hybrid with a sweet-meets-diesel profile, a creative and happy effect, and a forgiving, beginner-friendly plant that finishes by early October outdoors. If you want a heavier, sleepier evening strain, a kush indica will suit you better, and our review of Black Cherry OG shows one option.
