Quick Summary Ozone Robusta #4 is an indica-dominant hybrid known for its roasted coffee aroma and relaxing effects. It delivers solid body relaxation with a grounded head high. Best used in the evening when you want to unwind without total couch lock.
Strain Information
- Lineage: Kaya’s Koffee × Hamma Hamma

Effects Robusta #4 provides a smooth, balanced high that starts with mild cerebral relaxation before moving into the body. Most users report:
- Strong physical relaxation
- Reduced stress and tension
- Calm, grounded mental state
- Mild appetite increase
- Good for evening use
It’s not extremely sedative compared to heavier indicas, making it suitable for relaxed activities or light creative work before bed.

Aroma & Flavor This strain lives up to its name with a bold, roasted coffee aroma backed by dark cocoa, earthy, and gassy notes. On the exhale, you may notice subtle pine and spice. The flavor translates well when smoked or vaped, especially if the flower is fresh.
Appearance Buds are chunky and moderately frosty with dark green and purple hues. While not the most visually striking strain from Ozone, it has solid bag appeal for a mid-tier option.
Who Should Try Ozone Robusta #4
- People who enjoy coffee-forward, earthy strains
- Those looking for relaxing effects without total sedation
- Users who want decent flavor from an affordable brand
Who Should Skip It
- People chasing top-shelf potency or complex terpene profiles
- Those who prefer heavy knockout indicas
How Does It Compare to Other Ozone Strains? Robusta #4 stands out in the Ozone lineup for its actual flavor. Many Ozone strains can taste generic, but this one delivers noticeable coffee and earthy notes. Effects are reliable but not exceptional.

Final Verdict Ozone Robusta #4 is a solid mid-tier indica-dominant hybrid. It won’t blow you away, but it offers honest relaxation and better-than-average flavor for the price. If you see it fresh and reasonably priced, it’s worth trying — especially if you like coffee and earth notes.
Score: 7.6/10
