Bubba Kush
Bubba Kush is the heavy California indica that grower Matt 'Bubba' Berger stabilized in the late 1990s after an OG Kush plant pollinated an unknown Northern Lights-type indica in his garden. Reserva Privada released the most widely circulated seed version through DNA Genetics, preserving the dominant pre-98 Bubba phenotype that anchors the modern Kush family alongside OG. Plants stay short and stocky with broad-fingered leaves, finish in eight to nine weeks indoors, and produce dense, dark-green nugs that smell strongly of coffee and chocolate with a faint hash note. The high is one of the heaviest pure-indica expressions in commercial seed — slow, deeply physical, and reliably sedating, which is why it sits on most short lists for cannabis-assisted sleep.

Terpene profile
The aromatic compounds below shape how Bubba Kush 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
Humulene
Hoppy and earthy — appetite-suppressing and shared with hops and sage.

Lineage
Bubba Kush traces to OG Kush × Northern Lights. The cross sits in the Kush family, which influences both the terpene profile and the flowering structure described above.

Feed schedule for Bubba Kush
These EC and NPK targets are starting points calibrated for the strain's Indica 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
- 1.1-1.3 EC
- Early flower
- 1.2-1.4 EC, NPK 2-3-4
- Mid flower
- 1.5-1.7 EC, NPK 1-4-6
- Late flower
- 1.3-1.5 EC
- Final week
- Plain pH-balanced water for the last 5-7 days.

What to expect through the grow cycle
Bubba Kush is documented with a 9-week flower and a compact stretch typical of indica-leaning structure. 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 Bubba Kush concentrate the most observational notes on the late-flower ripening window. 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 Bubba Kush. 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)
- Bubba Kush is documented as having low stretch. Reports describe the plant roughly doubling in height during this phase as the indica-leaning 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 Bubba Kushnote 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 Bubba Kush 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 Bubba Kush 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 Bubba Kush runs end here, within the 8-9 week flowering range reported by the breeder.

Common questions about Bubba Kush
Why is Bubba Kush called Bubba?
The strain is named after grower Matt 'Bubba' Berger, who stabilized the phenotype in the late 1990s. The 'Pre-98' designation refers to plants from cuttings taken before 1998, considered the reference standard for the line.
Is Bubba Kush good for sleep?
Yes. The combination of dominant myrcene, secondary caryophyllene, and a 90 percent indica ratio produces one of the most reliably sedating highs in commercial seed. Most users are in bed within 45 minutes.
