These figures are ranges, not promises. Flowering time, harvest date and yield vary depending on growing conditions: the grower, the method and the season's weather. "Mold resistant" means mold tolerant: less prone to mold and slower to be affected. No strain is 100% mold resistant. How we set these numbers →
Taste & Aroma Profile
Sweet berry, like ripe blueberries, with earthy and spicy cedar undertones from the Haze — and, reviewers note, no skunk smell, which makes it one of the easier autoflowers to grow discreetly.
About Blue Dream
Genetics & strain profile
Blue Dream Autoflower is bred by Quebec Cannabis Seeds from Blueberry and Super Silver Haze genetics — the West Coast’s best-selling strain — on an autoflowering clock. It is a 70% sativa, 30% indica autoflower with 20% THC and 3 to 5% CBD, one of our QCS Originals, easy to grow even for beginners, and it carries our mould-tolerant badge. Seven reviews average 4.9 out of 5, and they describe exactly what Blue Dream is for: “I’m tired of strains that tranquilize you — great high but you can still function”, from a grower who uses it before mountain biking; “great calming without couch lock”; “fat, dense buds”, two of three plants with a blueish hue for one grower. First-timers report all five seeds up in four days planted straight into soil. The honest notes: one grower got “not a single blue plant”, and a regular buyer had one pack fail to germinate — replaced right away. Our seeds are guaranteed.
How Blue Dream Autoflower grows
Because it is an autoflower, it flowers on its own schedule without a change in light hours, and the plant reaches a manageable 60 to 90 cm, which suits a tent, a closet or a balcony. It flowers in 8 to 9 weeks; from seed, reviewers harvested at about ten and a half weeks. Indoors it gives up to 400 g/m²; outdoors up to 450 g per plant, with harvest in mid to late August from a May start — and because it does not wait for short days, a June or July start still finishes before the frost. It is a thirsty plant, as one experienced grower notes: water generously and feed at half strength even in soil, since autoflowers burn on full-strength nutrients. It resists pests and mould well, and the Haze side keeps the buds a little more open than a pure indica, which helps. Low-stress training is fine; skip topping and transplanting. Cool nights late in flower bring out the blue, but not every phenotype shows it.
Taste, aroma and effect
Sweet berry, like ripe blueberries, with earthy and spicy cedar undertones from the Haze — and, reviewers note, no skunk smell, which makes it one of the easier autoflowers to grow discreetly. The high is euphoric and relaxing but clear and functional: a daytime strain you can do things on, with the 3 to 5% CBD taking the edge off the Haze. At 20% THC it is moderate. For the photoperiod version, see Blue Dream; for other autoflowers, Girl Scout Cookies Autoflower and Cheesecake Autoflower; for the Blueberry side, Blueberry.

I bought this because I’m tired of strains that tranquilize you. This strain is awesome! Great high but you can still function and do things. I use this before mountain biking or playing ultimate. No skunk smell. Good yield. Thirsty plant. Use nutes even in soil, one half strength. Not a single blue plant but otherwise I’m very happy with it.
