Quebec Cookies strain at a glance

What is the Quebec Cookies strain?

Quebec Cookies is an original QCS strain: Quebec Cannabis Seeds is its original breeder, and these are our own genetics, bred in Quebec since 2015 by a grower with more than 35 years of experience.

Quebec Cookies is a sativa-dominant hybrid bred by Quebec Cannabis Seeds in Quebec. The name nods to the cookie family of strains that took over the market over the last decade, but the product page does not list the parents, so we will not claim a particular lineage. What it does tell us is the profile: 70% sativa, 30% indica, 19 to 25% THC, a citrus and spice flavour with a sweet finish, and an uplifting, euphoric effect.

The Quebec Cookies strain also has a growing profile that suits a Canadian garden: it is rated easy to moderate, the page says it resists common pests and mould (meaning mould tolerant, not mould-proof), and it yields well. Indoors expect 500 to 600 g/m². Outdoors it finishes in late October, so it suits gardens where autumn stays mild.

Is Quebec Cookies indica or sativa?

Quebec Cookies is listed as 70% sativa and 30% indica, which makes it sativa-dominant. Growers who know sativa-leaning plants will recognise the pattern: taller than a pure indica, with more internodal stretch in the first weeks of flower and a flowering window that is a little longer than most indica-dominant plants. At 8 to 9 weeks, though, it is not a slow one.

Consumers of sativa-leaning cannabis commonly describe a brighter, more mentally active experience than with indica-dominant plants, which fits the uplifting and euphoric description on the page. Curious about the other side of the family? Our guide to what indica does to you makes a useful contrast.

Smell and flavour

QCS lists the taste as citrus and spice, followed by a sweet finish. That is a lively profile, closer to peel and pepper than to the heavy dessert notes people often associate with the word cookies. Citrus-forward cannabis is often linked by consumers to the terpene limonene, and spicy notes to caryophyllene, though every plant is different and the only real test is a properly cured jar.

Because the profile is bright rather than heavy, it can be a good choice for people who find very dessert-sweet strains cloying. Slow drying in a cool, dark room helps preserve the citrus top note.

Quebec Cookies effects

The QCS page describes the effect as uplifting and euphoric. Sativa-dominant cannabis is commonly described by consumers as energising and creative, often as a daytime choice, but individual responses vary a lot and tolerance matters. We make no medical claims.

With a THC range of 19 to 25%, this is a strong strain at the upper end, so start low and go slow, especially if you are new to sativa-style plants that can feel racy at higher doses.

How strong is Quebec Cookies? THC content

QCS lists Quebec Cookies at 19 to 25% THC. The spread matters: a plant at 19% is a solid mid-strength experience, while one near 25% is a heavy hitter. Where you land depends on phenotype, light intensity, nutrition, harvest timing and the cure. A careful grower can usually push towards the top of the range.

If you want something stronger still, browse our seeds over 25% THC. Other seed companies sell Cookies-style strains with different lineages, so numbers elsewhere may differ; those on this page are for the QCS version.

Growing Quebec Cookies: flowering time and yield

Indoors, Quebec Cookies flowers in 8 to 9 weeks and yields 500 to 600 g/m² under good conditions. Outdoors it is ready in late October and QCS lists up to 750 g per plant, so it likes a long, mild autumn. In a short Quebec season, consider growing it in pots you can move into shelter, or in a greenhouse.

Tips for sativa-dominant plants: expect stretch, so top or train early and keep a flat canopy; use a net so heavy tops do not flop; and give plants room because yields reward space. The page rates it easy to moderate and says it resists common pests and mould, but good airflow is still your best protection in the last weeks.

Is Quebec Cookies right for you?

Quebec Cookies suits growers who want a sativa-dominant plant with a bright citrus and spice profile, strong yields and no need for expert-level skill. It is a less natural fit for a short season without a greenhouse, since the outdoor harvest comes in late October. Compare it with our reviews of Blue God or Black Cherry OG, or see all feminized seeds.
