Growing Blueberry: flowering time and seed-line specs
Published cultivation specifications describe seed lines and listings, not a single guaranteed Blueberry plant. SeedFinder’s DJ Short record gives 45–55 days indoors; Dutch Passion gives 8–9 weeks for its line, while Weedmaps gives 49–56 days.1,2,3

What the sources describe
DJ Short Seeds describes a medium-to-tall indica with long side branches, dense flowers and red, purple and blue hues; Dutch Passion describes broad fan leaves, compact growth and sturdy stems for its version.2,6
Leafly and Dutch Passion both describe sea-of-green suitability for their records or seed line. These are cultivation descriptions, not a guarantee of a particular result.2,4
What to verify before comparing seed information
The original DJ Short entry and modern commercial seed listings should not be treated as interchangeable. SeedFinder says DJ Short’s Blueberry was never available as feminized seed, while Dutch Passion and ILGM offer feminized Blueberry products with their own descriptions.1,2,5
Seeds and the law in the US
The Congressional Research Service says the amended hemp definition excludes viable seeds from a cannabis plant exceeding 0.3% total THC, including THCA, on a dry-weight basis. It says that exclusion and other portions of the definition are delayed until Dec. 11, 2026, while certain synthetic-cannabinoid exclusions take effect Nov. 12, 2026.7 This site does not sell seeds.
