What is the Blue Dream strain?
Blue Dream is a sativa-dominant hybrid of Blueberry and Haze that came out of California, most likely the Santa Cruz area, in the early 2000s. Leafly calls it the most popular strain on its site, and High Times describes it dominating West Coast dispensaries from about 2003 to 2011. Blue Dream usually tests around 17–24% THC with little CBD, flowers in 9 to 10 weeks and is known as a big, forgiving producer.
Ratio from AllBud. Humboldt Seed Organisation describes its feminized Blue Dream as mostly sativa.
Humboldt Seed Organisation rates Blue Dream's yield as high indoors and very high outdoors, and growers have long found it easier than OG-type strains.

Where does the Blue Dream strain come from?
Blue Dream is a cross of Blueberry and Haze that surfaced in California, most likely around Santa Cruz, in the early 2000s, and its original breeder has never been confirmed. Ed Rosenthal told High Times the cross was Haze × DJ Short's Blueberry, and SeedFinder lists Blueberry × Super Silver Haze as the probable parentage.
Which Haze went into Blue Dream is still argued. Some California growers credit Santa Cruz Haze from the Haze Brothers, while others say Super Silver Haze. Blue Dream first spread through clone cuts passed between growers and dispensaries, and today several seed companies, including Humboldt Seed Organisation, sell feminized versions bred from those genetics.
Why did Blue Dream become so popular?
Blue Dream took off because it was easy to grow, yielded heavily and had a sweet, crowd-pleasing aroma. Growers quoted by High Times say Blue Dream was much easier to grow than OG and cheaper for dispensaries to buy while still good quality, which led to huge production during California's green rush. Leafly still ranks Blue Dream as the most popular strain on its site.
Not every Blue Dream is the same plant. High Times reports a long-running rumor of two cuts, one more sativa and one more indica, and a Leafbuyer and Trichome Institute review (not a scientific study) named Blue Dream Colorado's most counterfeited strain.

Reported effects

How do you grow Blue Dream seeds?
Blue Dream seeds grow into vigorous, wide plants that are easy to keep healthy if you control their size: top early, train the branches flat, flower for 9 to 10 weeks, and watch for powdery mildew and spider mites.
- GerminateAbout 1 week
Blue Dream seedlings grow quickly; move them into larger pots soon after the third leaf set so roots don't circle.
- Vegetate4–6 weeks indoors
Top Blue Dream once or twice and pull the branches outward, because the plant grows fast and wide and stretches hard later.
- Flower9–10 weeks
Expect Blue Dream to stretch after the switch to 12/12 and build long, heavy colas; support them and keep air moving through the canopy.
- HarvestDay 63–70 indoors · early–mid October outdoors
Don't rush Blue Dream: growers quoted by High Times blame early harvests for weak flavor and potency.
Grow tips for Blue Dream
- Plan for the stretch. Leafly notes Blue Dream can stretch in flower, so flip it at about half your final target height and fill a SCROG net before the switch.
- Scout for mildew and mites. Leafly's grow notes list Blue Dream as susceptible to powdery mildew and spider mites. Check leaf undersides weekly and keep humidity in check.
- Watch the big colas for rot. Blue Dream's large, dense colas can hold moisture late in bloom, so thin inner leaves and avoid wet, still air in the last weeks.
- Let it finish fully. Blue Dream reaches its best flavor late; wait for mostly cloudy trichomes instead of cutting at the first sign of amber pistils.
- Give outdoor plants space. Outdoors, Blue Dream grows big and wide and finishes in early to mid-October, so plant it where it gets full sun and room to spread.

Matthew Campos –
This strain makes me feel really relaxed and even joyful; on occasion, she could even assist me in solving my difficulties. Unlike other strains, this baby grows incredibly easily and requires a lot of care. She looks amazing in my hidden garden, showcasing her dense, bushy nugs. This is by far the best strain I’ve ever purchased online, I can tell. In eight weeks, it produced the healthiest and thickest buds for me! It didn’t take up a lot of room. All I can say is that its flavors are just wonderful and amazing!
Walter Melendrez –
Fcking awesome! Very easy-to-grow plant and does need a lot of care, unlike other strains, this baby really turns out great on my secret garden; she really shows off her bushy dense nugs. Her smell of sweet fruity scent really fills the room when she’s lit up! My baby could give me deep relaxation and even a happy feeling; she could even sometimes help me with my headaches.

For its flavors, I can taste the blueberry, vanilla, and tropical sticking into my mouth. After a puff, I can feel the energy in my body increasing as well as my creativity.
