Quebec Blue – Feminized Cannabis Seeds | Canada
Quebec Blue Cannabis Seeds Feminized
Quebec Blue is a feminized, Sativa-dominant hybrid (70% Sativa / 30% Indica) bred from Blue Fire × Grand Daddy Purple, and one of the flagship strains in our Quebec cannabis seeds line. It tests at approximately 23% THC with minimal CBD (under 1%), flowers in 8–10 weeks, stays small (0–4 ft indoors and outdoors), and yields around 500–600 g/m² indoors or up to ~500–750 g per plant outdoors, typically harvesting early to mid-October. The genetics combine Blue Fire's energizing Sativa vigor and sweet, fruity brightness with Grand Daddy Purple's stable Indica structure and mellow sedation, producing reported effects that are uplifting and creative before mellowing into calm relaxation.
Genetics: Blue Fire × Grand Daddy Purple
Blue Fire contributes energizing Sativa influence, sweetness, and a berry-meets-floral taste, plus robust vigor and explosive bud formation.
Grand Daddy Purple contributes heavy sedation, sweet grape-laced undertones, brilliant coloration, and a smooth, luscious smoke.

Flavor, Aroma & Terpenes
Flavor: An immediate peppery bite reminiscent of mild chili or aromatic herbs, softened by a gentle sweet, berry-laced background that becomes more noticeable on the exhale, with earthy and faint citrus-pine notes underneath.
Key terpenes: Camphene, myrcene, phellandrene, terpinolene, and valencene.
Effects
Commonly reported: calm, creative, happy, relaxing, long-lasting, with a mild psychedelic-adjacent quality some users describe at higher doses. Typically starts with an energizing mental spark good for socializing or creative work, gradually mellowing into gentle physical relaxation without heavy sedation at moderate doses.
Effects vary by person and dose. Not medical advice.
Reported Uses
Some users report the balanced profile as supportive for stress, low mood, general aches, tension headaches, or reduced appetite. This reflects general reported use, not medical advice or a treatment claim for any diagnosed condition — consult a healthcare provider before using cannabis for anxiety, depression, chronic pain, insomnia, or any other medical condition.
Growing Conditions
- Indoor: Small stature suits tents or closets; SOG or light LST harnesses the strain's vigorous lateral branching. Good ventilation prevents mold on resinous buds.
- Outdoor: Best in continental or temperate climates; sunlit spots, well-draining soil, and consistent feeding support the higher end of the yield range.
- Greenhouse: Combines natural sunlight with protection from abrupt climate shifts.
Harvesting & Curing
For a deeper look at each stage, see our guide to drying vs. curing marijuana.
- Harvest timing: Mostly milky trichomes with some amber for balanced sedation and vibrant flavor; outdoors, aim for early to mid-October before harsh weather sets in.
- Dry: 7–14 days, dark and airy, ~50% humidity — rushing this step mutes the strain's signature spicy notes.
- Cure: Airtight jars once stems snap rather than bend, burped daily at first; two weeks or longer clarifies the peppery aroma and amplifies subtle sweet notes.
