The Cross
Blue Star Genetics built Old World Genetics as F-4 Blueberry crossed to OTM. Buy Old World Genetics seeds if you want DJ Short's 1998 Blueberry line intact. F-4 means four generations selected from the original. Breeder aimed to stack berry flavor, resin production, and indica structure. OTM adds sour gas edge. They hit the mark on preservation. No data says otherwise.
What Each Parent Brings
F-4 Blueberry delivers tight nodes, purple potential, and fruit punch terps. DJ Short's pool shows in every bud: dense, resin-soaked calyxes. Expect 20 to 25 percent THC in keepers, though unconfirmed here. OTM kicks in sour, gassy fuel. It loosens structure slightly, boosts yield. Cross tempers Blueberry's finickiness. Breeder claims hold: heritage traits dominate.
Blueberry Side
- Berry aroma, sweet to tart.
- Short flowering nodes.
- Resin heads early.
OTM Side
- Gassy exhale.
- Stretch control.
- Bag appeal boost.
The Phenotypes
Variation runs true to Blueberry lines. Indica doms squat at three feet, stack buds like bricks. Sativa leans stretch to five feet, looser but heavier yielding. Sour gas shows in 20 percent of plants, fem line reports say. Run 10 packs minimum. Cut stretchers unless you have height. Keep bricks for moms. No one-hit wonder here. Genetics deliver.
Finding the Keeper
Vegetative: hunt vigor. Blue tints week four, keepers purple fast. Structure firm, no foxtail. Aroma starts berry, gas underneath. Flower week three: resin beads. Trichs milky by week seven, unconfirmed time. Buds firm up, no popcorn. Test sniff: sweet gas wins. Yield 400 to 500 grams square meter indoors, outdoors double in right sun. Reverse now if male sacks. Females show preflowers early.
Stage by Stage
- Veg: Compact interns, blue stems.
- Flower start: Resin frost.
- Mid flower: Berry swell.
- Chop: 30 percent amber.
In the Garden
Mediums lean coco or soil. pH six point zero. Low stretch means 18-hour veg fine. Flower 18 to six. Feed light nitrogen early, bloom nutes week three. Prune lowers for airflow. Yields solid, no fuss. Outdoors finishes early October. Hermie risk low from vault stock.
The Experience
Indica couch lock with berry aftertaste. Gas lingers on exhale. Hits body first, head mellow follows. Two bowls max for focus. Suits evening. No race claims, just what lines do.
