The Cross
Blue Star buy Blue Star seeds pairs F4 Blueberry with OTM. Breeder targeted dank floral blueberry jam traits from the F4 mother. If you want to buy F4 Blueberry seeds, this pulls straight from DJ Short's 1998 line. Limited fem production took three reversal tries for 52 seeds. They got a juicy fruit pheno and crossed it back to Blueberry mom. Cross hit the mark on fruit intensity variation. No hype, just selection work.
What Each Parent Brings
F4 Blueberry delivers the core: dense floral notes, thick blueberry jam aroma, resin heads that stack early. DJ Short's old gen stock, stabilized over generations. Expect 56 to 63 day flower, balanced hybrid structure. OTM adds structure punch. Brings vigor, branch strength, yield boost without washing out fruit. Not a flavor bomb itself, but holds the Blueberry traits without stretch or weakness. Confirmed from breeding notes: OTM selected to amplify, not dilute.
Blueberry Side
Ripens to purple calyx if cold snapped. Terps lean purple fruit, earth base. THC unknown, but old Blueberry lines test mid-20s in good hands.
OTM Side
Keeps nodes tight, resists mold in flower stretch. Adds a pepper edge to cut pure sweetness. Breeder claims hold up in phenotype reports.
The Phenotypes
Variation runs fruit to floral. One in four hits deep blueberry jam. Others lean juicy fruit or muted purple. No duds reported, but hunt for the keeper. Blue Star Blueberry seeds show why old crosses need pheno runs. Cut anything under two weeks flower time or no fruit terps by week four. Keep the dank ones. Breeder notes confirm: phenotype spread in fruitiness and intensity.
- Blueberry dominant: 25 percent, thick nugs, jam terps.
- Juicy fruit: 40 percent, faster veg, lighter yield.
- Floral hybrid: 35 percent, resin heavy, balanced smoke.
Finding the Keeper
Seedling stage: Look for fast taproot, no triples. Veg: Bushy interns, no foxtail. Flower week three: Resin beads on fans, fruit terp spike. Structure: Eight to 10 nodes by flip, colas stack even. Aroma: Blueberry must cut through by week five, or cull. Growth pattern: 2 to 3 foot indoor, minimal stretch. Blue Star Genetics OTM influence shows in side branch yield. Test smoke at 56 days: Dank floral wins.
In the Garden
Run under 1000w HPS or LED equiv. Veg 4 to 6 weeks, flip at 18 inches. Flower 56 to 63 days, no re-veg risk. Yields 0.5 to 1 gram per watt with CO2. Prune lowers week two flower. Stable, but pheno hunt pays off. Old vault genetics hold true.
The Experience
Balanced hybrid hit: cerebral lift into body calm. Blueberry sweetness lingers, floral back. Good for day end, not couch lock. Effects match old DJ Short reports. No medical talk, just what growers note.
