Bubblegum
Bubblegum is the Indiana-origin hybrid that growers stabilized in the American Midwest through the late 1980s before TH Seeds carried the genetics to Amsterdam and released the most widely circulated feminized seed version in the mid-1990s. The strain became known for one of the most distinctive sweet-candy terpene profiles in commercial cannabis — pink bubblegum on the inhale with a faint earthy exhale that holds the flavor through long cures. TH Seeds' release took the High Times Cannabis Cup in 1994 and 1995, putting Bubblegum on permanent rotation in Amsterdam coffeeshops. Plants finish in eight to nine weeks indoors with medium-density buds, pink-tinted pistils, and a moderate trichome layer. The high is balanced cerebral-physical with a euphoric opening and a long mellow tail, recommended as a flexible afternoon or social strain.

Terpene profile
The aromatic compounds below shape how Bubblegum smells, tastes, and ultimately feels in the body.
- dominant
Myrcene
Sedating, musky, herbal — commonly linked to couch-lock effects.
- secondary
Caryophyllene
Peppery and spicy — the only terpene that binds CB2 receptors, studied for anti-inflammatory action.
- secondary
Limonene
Uplifting citrus — typically associated with mood elevation and stress relief.
- minor
Linalool
Floral and lavender-like — calming, often noted for sleep and anxiety support.

Feed schedule for Bubblegum
These EC and NPK targets are starting points calibrated for the strain's Hybrid lean and easy difficulty rating — not gospel. Drop 15-20% off any EC ceiling on your first run and let the plant tell you where it actually wants to feed.
Suggested feed schedule
- Late veg
- 1.0-1.2 EC
- Early flower
- 1.1-1.3 EC, NPK 2-2-4
- Mid flower
- 1.4-1.6 EC, NPK 1-3-5
- Late flower
- 1.2-1.4 EC
- Final week
- Plain pH-balanced water for the last 5-7 days.

What to expect through the grow cycle
Bubblegum is documented with a 9-week flower split across the standard hybrid phases. The visual below maps a documented 13-week cycle built from 4weeks of vegetative growth and the strain's published flowering window.
Published grow reports for Bubblegum concentrate the most observational notes on the mid-to-late flower transition. This timeline is descriptive — it reflects what reports document, not a how-to. Actual week-to-week behaviour varies with phenotype, light intensity, pot size, and environment.
Phase details
- Veg (weeks 1-4)
- The documented vegetative period for Bubblegum. Plants establish root structure, leaf canopy, and node count before flower triggering, with a easy difficulty rating shaping how forgiving the early canopy work tends to be.
- Stretch (weeks 5-7)
- Bubblegum is documented as having moderate stretch. Reports describe the plant roughly doubling in height during this phase as the hybrid structure establishes its final flowering frame.
- Bud sites (weeks 8-9)
- Pre-flowers form at the nodes and calyxes begin to develop. Grow reports for Bubblegumnote this as the window where the canopy's eventual bud distribution becomes visible.
- Bud development (weeks 10-11)
- Flowers thicken and calyxes fatten through this phase. Documented Bubblegum runs show the bulk of visible flower mass accumulating here, with resin production accelerating toward the end.
- Ripening (week 12)
- Trichomes transition from clear toward cloudy and amber. Reports for Bubblegum describe the Myrcene-led terpene profile maturing through this window, with aroma sharpening week over week.
- Final (week 13)
- Calyx swelling is documented as complete and the harvest window opens. Published Bubblegum runs end here, within the 8-9 week flowering range reported by the breeder.

Common questions about Bubblegum
Did Bubblegum originate in Indiana?
Yes — the working line was stabilized by growers in the American Midwest, specifically traced to Indiana, through the late 1980s. TH Seeds brought the genetics to Amsterdam in the early 1990s and released the most widely distributed feminized version.
Why does Bubblegum smell like candy?
The combination of dominant myrcene with secondary linalool produces an unusual sweet floral expression that reads as pink bubblegum on the inhale. The expression is distinctive enough that experienced growers can identify the strain by smell alone.
