Blue Dream

The Blue Dream cannabis strain crosses Blueberry and Haze strains and measures approximately 18% THC, with little to no CBD. Growth patterns tend to be sativa-like, so expect tall plants if you’re growing this strain. Blue Dream is a sativa-dominant hybrid strain comprising around 60% sativa and 40% indica.

Blue Dream is one of the most popular varieties of cannabis. It is a favorite among novice and veteran cannabis consumers due to its pleasant, sweet berries, sometimes peppery flavor, and manageable effects. This varietal of cannabis could help manage chronic pain, anxiety, and depression.

Due to the popularity of the Blue Dream cannabis strain, there are various versions of it, many built from different varieties of Haze, Blueberry, or some combination of the two. The original Blue Dream is a cross between Mr. Nice’s/Sensi Seeds’ Super Silver Haze and DJ Short’s Blueberry. DJ Short’s seed bank carries a distinct version of Blue Dream called Azure Haze.

growing strains

Compared to many other tall sativas, Blue Dream is comparatively fast and easy to grow, perhaps partly due to the influence of its indica-leaning Blueberry genetics. Blue Dream is also sensitive to small changes in climate and is thought to be best grown indoors. However, as a sativa-leaning variety of cannabis, it can grow quite tall, so some people in subtropical or Mediterranean climates may prefer to plant it outdoors.

Blue Dream also seems to like nutrients, especially nitrogen. The ideal pH for soil is between 6.0 and 7.0 or 5.5 and 6.5 for hydroponic growth. Blue Dream thrives in a “sea of green” (SoG) setup, so it is wise to find a good mother, take cuttings, and plant clones. Expect yields of 15 and 22 ounces per square meter if grown correctly.


Blue Dream can grow to between 4 and 6 feet tall.

Humidity and Temperature

The following refers to indoor grow rooms, where temperature and humidity can be controlled.

Seedling stage: 72-78 degrees Fahrenheit (22-25.5 degrees Celsius); humidity range = 30%-50%
Vegetative stage: similar temperature to above, but increase humidity to about 55%
Flowering stage: ideal temperature is 80-85 degrees Fahrenheit (26.6-29.4 degrees Celsius); humidity should be between 30-40%. Using a dehumidifier can decrease humidity levels gradually between the vegetative and flowering stages.


Blue Dream takes 8-9 weeks to finish flowering. If growing outdoors in the Northern hemisphere, expect Blue Dream to be ready to harvest by mid-September to mid-October. In the Southern hemisphere, expect to harvest around February or March.

Frequently Asked Questions

Is Blue Dream good for anxiety?

It is difficult to say conclusively whether any particular variety of cannabis is suitable for a specific ailment or condition. Strain names can only tell you so much, so it is best to look at the test results and see what cannabinoids and terpenes the cannabis contains.

With this in mind, people have reported that Blue Dream helps manage anxiety due to its relaxing effects. Blue Dream’s uplifting effects also suggest that it could help manage other challenges that often arise alongside anxiety, like stress and depression.

However, some people have also reported paranoia as an adverse side effect of using Blue Dream, so taking it slow and low (low dose over an extended period) and choosing a Blue Dream with moderate THC content might be ideal for novice users.

Why is Blue Dream so popular?

Cannabis varieties, like clothes, tend to go in and out of fashion, with a handful of types becoming all-time classics beloved by novices and connoisseurs alike. Blue Dream is one of these all-time classics for a few good reasons.

Blue Dream has a pleasant taste and aroma: sweet, blueberry, and peppery, which many people enjoy.

The effects are pretty pleasant. Blue Dream has a moderate THC content, and terpenes give the strain a balance between uplifting and relaxing effects. CBG may also help contribute to Blue Dream’s energizing effects. CBD is not always found in Blue Dream, but it is sometimes, which could help balance THC’s effects.

Blue Dream’s parents (Blueberry and Super Silver Haze) are both prize-winning cannabis varieties. DJ Short (Blueberry) and Shantibaba (Super Silver Haze) are legendary breeders who have created some of the most successful cannabis varieties available today. Blue Dream is an excellent expression and blends the quality genetics these two breeders produce.

Is Blue Dream good for sleep?

Due to its uplifting effects, Blue Dream isn’t often recommended for sleep issues like insomnia. However, careful dosing over the day may help reduce anxiety overall, which can help aid sleep at night.
