STM Canna RocketBox Pro
by STM Canna
| Price | $120,000+ |
| Throughput | ~1,000/hr (rated) |
| Formats | cones |
| Key Differentiator | High-volume cone-fill system (requires pairing with STM's Atomic Closer for complete workflow) — achieves ~1,000 j*ints per hour at real-world operating conditions. |
Strengths
- Reliable cone-filling at high volumes
- Widely deployed across large MSOs — proven at scale
- Strong support network and parts availability
- Fast changeover between pre-roll sizes
Weaknesses
- Not a complete system — requires pairing with STM's Atomic Closer (adds ~$60K)
- Cone-fill only — no straight roll or blunt capability
- Real-world throughput ~1,000/hr (not the rated 2,500/hr for 1-gram SKUs)
- Requires consistently ground, properly moisture-controlled material
Overview
The STM Canna RocketBox Pro is a high-volume cone-filling system, but it’s not a standalone solution. You’ll need to pair it with STM’s Atomic Closer for the complete workflow, bringing total system cost to ~$120K+. Real-world throughput averages around 1,000 jints per hour for typical 1-gram pre-rolls (despite rated specs of 2,500/hr, operators consistently report 1,000/hr with real-world material). For large dispensries running pre-rolls as a high-volume commodity product with proper material prep, this setup can handle significant volume.
The machine fills pre-formed cones using a vibrational filling method combined with a tamping system. Consistency is good — not exceptional. Weight variance is within acceptable commercial tolerances, but operators sourcing premium flower will notice the difference versus a rolling machine.
Who Makes It
STM Canna is one of the most established names in pre-roll automation. The RocketBox Pro sits at the top of their commercial line and benefits from STM’s large installer and support network across the US and Canada.
Operator Impressions
Widely regarded as the workhorse of large-scale pre-roll operations. Operators frequently cite reliability and parts availability as key advantages. The consistent feedback: material prep is everything. The machine rewards well-ground, moisture-controlled input and punishes inconsistent prep with jams and weight variance.
Total Cost of Ownership
Total system cost of ~$120K+ (RocketBox Pro + Atomic Closer) positions this in the mid-to-premium range. At real-world throughput of 1,000/hr, the cost-per-unit is reasonable for high-volume operations, but the upfront capital is significant. Maintenance costs are well-documented and parts are widely available, which is a major advantage for operators prioritizing reliability.
Best-Fit Profile
High-volume dispens*ries and MSOs running commodity pre-rolls at scale. Optimal when throughput and cost efficiency are the primary objectives and premium brand positioning is secondary.
