DJ Short

Origins and early work

DJ Short began selecting cannabis in the late 1970s, working with landrace and early hybrid material circulating in the United States after the 'great Thai stick era' of 1975–1979. In his own account, published in Cultivating Exceptional Cannabis (2003), he started from a small population of seeds found in imported flower, including Highland Thai, Chocolate Thai, Purple Thai, and Afghani indica varieties ^[1] Weak / limited. The 'weak' label here reflects that the historical record relies primarily on Short's own retrospective writing and interviews — there are no contemporaneous lab records or third-party documentation of the original 1979–1980 selections.

Short has described his early method as a slow, small-scale pheno-hunt: germinating modest numbers of seeds, flowering them, and keeping mothers from standouts rather than running large F2 populations. This is the same approach most hobbyist breeders of the pre-internet era used, and it shapes how his lines behave today — they tend to be variable, with multiple distinct phenotypes rather than a uniform 'IBL' Anecdote.

Blueberry and the fruit-flavored family

The cultivar that made Short's name is Blueberry, a cross derived from Purple Thai and Afghani parents. Blueberry was bred in the 1980s but only became commercially famous in the 1990s, when seeds were released through the Dutch seed bank Dutch Passion ^[2]. Blueberry won the High Times Cannabis Cup for Best Indica in 2000 ^[3] Strong evidence — this is a matter of contemporaneous magazine record.

Closely related releases from the same gene pool include Flo (a more sativa-leaning selection), Blue Velvet, Blue Moonshine, and Old Time Moonshine. Together these formed what Short and others have called the 'Blue family.' The fruity, candy-like aroma associated with these plants is widely attributed in marketing copy to high myrcene or specific terpene ratios, but published terpene analyses of modern 'Blueberry' samples vary widely between labs and cuts Disputed. The aroma is real and reproducible in certain phenotypes; the simple terpene explanation often given in dispensary copy is folklore Weak / limited.

Relationship with Dutch Passion and later self-publishing

Short licensed Blueberry and Flo to Dutch Passion in the early 1990s, which is how the genetics first reached a global market via the Dutch seed catalog system ^[2]. He later parted ways with Dutch Passion over disputes about how the genetics were being maintained and represented — Short publicly stated in interviews with Cannabis Culture and High Times during the 2000s that the seed-bank versions had drifted from his originals ^[4] Weak / limited.

From the mid-2000s onward, Short released seeds under his own banner (variously 'DJ Short Seeds' and 'DJ Short / Delta-9 Collective'), often through North American seed retailers. Because cannabis breeding has no formal cultivar registration system, multiple seed companies have sold 'Blueberry' over the decades with no enforceable claim to authenticity. This is a structural problem in cannabis, not unique to Short's lines ^[5].

Influence on later breeders

Blueberry genetics show up, by stated lineage, in a large number of later commercial cultivars: Blue Dream (Blueberry × Haze, origin attributed to Santa Cruz, California in the mid-2000s), Blueberry Headband, Berry White, Blue Cheese, and many others. The accuracy of these lineage claims varies — they rely on breeder testimony rather than genetic verification Disputed. Phylogenetic work by Sawler et al. (2015) and later Vergara et al. demonstrated that strain-name claims in cannabis often do not match genetic clustering ^[6] Strong evidence, so 'descended from Blueberry' should be read as a marketing lineage, not a verified pedigree.

That caveat aside, Short is genuinely one of the small group of identifiable North American breeders — alongside figures like Neville Schoenmakers, Sam the Skunkman, and the Haze Brothers — whose named selections shaped what the commercial seed market looked like by the 2000s.

Myths and clarifications

A few claims about DJ Short circulate widely and deserve flagging:

• 'DJ Short invented the indica/sativa hybrid.' False. Afghan-Thai crosses predate his work by at least a decade; Sacred Seed Co.'s Skunk #1 (released 1978) is the better-documented early hybrid ^[5] Strong evidence.
• 'Original Blueberry is extinct / only DJ has it.' Partly disputed. Short himself has said the cut he keeps is the closest to his original selection, but no genetic comparison has been published to verify this No data.
• 'Blueberry's color and flavor come from anthocyanins reacting with myrcene.' Folklore. Anthocyanins produce purple coloration in cold conditions; they are not responsible for blueberry flavor, and there is no published mechanism linking them to myrcene No data. The fruity aroma in Blueberry phenotypes is more plausibly tied to specific ester and terpene combinations that have not been fully characterized in peer-reviewed work.

When evaluating any 'DJ Short' seed pack on the market today, the honest framing is: you are buying genetics in the Blueberry lineage, selected at some remove from the breeder's original 1980s population, with no third-party verification system to confirm authenticity.
