Blue Dream

The parent lines of Blue Dream are well documented, but its origin is not: the strain crosses Blueberry with a Haze and appeared around 2003 as a clone-only cutting in dispensaries in Santa Cruz, California, without any breeder ever claiming it as their own. Sativa-leaning at roughly 60 % sativa, it was passed on clonally for years before seed versions under the same name followed.

Genetics and Origin:

Cannabis author Ed Rosenthal classifies the strain as a cross of Haze and DJ Short's Blueberry. Which Haze was involved remains unclear: batch records from a producer who grows the line commercially cite Blueberry from DJ Short and a Santa Cruz Haze, Humboldt Seed Organization lists Blueberry x Super Silver Haze for its own version, and DNA Genetics lists Blueberry x Haze #1. A journalistic investigation additionally documents a version from Mystic Seeds, described as Blueberry x OG Kush, and concludes that no single originator can be identified.

Documented descendants include Atomic Blue Dream from Sensi Seeds, Blue Amnesia from Amsterdam Genetics, Alki Haze from South Bay Genetics, and Blue Dream Auto from Humboldt Seed Organization, for which the breeder states a Ruderalis cross was used.

Aroma and Flavor:

The aroma is dominated by sweet blueberry and berry notes, complemented by earthy and vanilla-like undertones. In flavor, berry, vanilla and herbal nuances are mentioned. Humboldt Seed Organization describes Haze, citrus and cedar in the aroma of its own version, along with a lemony flavor with pine and incense; Blimburn Seeds additionally lists mango.

Effects:

User reports describe a clear, head-focused onset with elevated mood, euphoria and increased creativity, often talkative, later accompanied by physical relaxation. Dry mouth, dry eyes and dizziness are mentioned as side effects; some reviews report restlessness, anxiety and paranoia at higher amounts.

THC and CBD Content:

For commercially grown flower of this strain, 39 batch analyses have been published. They range from 18 to 23.7 % THC at 0.01 to 0.09 % CBD, varying considerably by batch, cultivation and phenotype. One flower of this strain sold as medical cannabis is listed at 15 % THC and under 1 % CBD. Separate from this are the figures from seed suppliers: Humboldt Seed Organization states 19 % THC and 0.1 % CBD, while Blimburn Seeds and DNA Genetics each state 17 to 24 % THC.

Lab Results:

The same batches were tested for terpenes. Total content ranges from 1.73 to 4.61 %. Myrcene leads almost throughout at 0.61 to 2.223 %, followed by caryophyllene at 0.30 to 1.05 %, ocimene at 0.06 to 0.81 % and humulene at 0.14 to 0.29 %. Other strain descriptions place pinene second in the profile; in these analyses it appears only in trace amounts, while farnesene repeatedly ranks among the four strongest terpenes.

Cultivation:

Strain descriptions cite 8 to 10 weeks of flowering and mid-October as the outdoor harvest time, up to 430 g/m² indoors and up to 500 g per plant outdoors. The strain is grown both indoors and outdoors, with a preference for temperate locations with plenty of midday sun; difficulty is rated moderate. It is described as suitable for the Sea of Green method, with powdery mildew and spider mites noted as weak points.

Versions from Different Breeders:

Seed versions differ considerably in their stated figures. Humboldt Seed Organization lists its own feminized version at 70 % sativa and 30 % indica, 65 to 70 days of flowering, 400 to 600 g/m² indoors, 2000 to 3000 g per plant outdoors, 3 to 4 m growth height, and harvest in mid-October. Blimburn Seeds states 8 to 10 weeks, 600 g/m², 500 to 700 g per plant, 2 m height, and a 1st place in the outdoor category of Spannabis 2011. DNA Genetics also states 8 to 10 weeks. In addition, there is the autoflowering Blue Dream Auto from Humboldt Seed Organization, with 13 % THC, a total cycle of 70 to 75 days from germination to harvest, 30 to 75 g per plant indoors, and a height of 1 to 1.5 m.

Community Experiences:

One point recurs throughout grow reports: the stated flowering time is often exceeded. One grower harvested after more than 80 days of flowering; on one plant, trichomes remained clear even after 90 days, while another report cites 8 to 9 weeks. Those growing from seed describe strong variation between plants, since the lines in circulation are reproductions and do not match the original cutting. Experiences on moisture tolerance conflict: one outdoor grow survived two weeks of continuous rain with almost no mold. Also documented is a deep purple phenotype, which the grower attributes to the Blueberry lineage and to cold; the seedlings were kept at 15 to 17 °C.
