Is your facility actually ready for the 4/20 pre-roll rush?
If your plan is “add more hands,” you’re already paying the tax. Over time, temp training, inconsistent packs, and that last-minute rework pile that eats your margin.
4/20 demand doesn’t just spike. It compresses time. You’re trying to hit bigger numbers with the same crew, the same space, and the same QA pressure. Labor turns into the limiter fast, and quality gets blamed when the real problem is throughput.
That’s why we’re running the STM Canna 4/20 Sale. It’s built for producers who want more daily output without turning the break room into a hand-rolling classroom.
Sale ends 4/21/26.
The 4/20 bottleneck isn’t “pre-rolls.” It’s steps.
Most lines don’t fall behind at the same spot. They fall behind wherever hands are still doing repetitive work.
Grind prep gets rushed. Density gets inconsistent. Closing becomes a slow walk at the end of the shift, where everyone is tired, and your brand still needs to look clean on the shelf.
Pick the bundle that fixes the step that’s actually stopping your line.
Perfect Your Prep: The Mini Grind and Roll Bundle
A premium pre-roll starts before the cone ever gets filled. If your grind swings batch to batch, everything downstream gets harder. Packing gets weird. Burn gets weird. Your team starts “fixing” it by feel, and that’s where consistency goes to die.
This bundle gives you a tight prep-and-fill station that fits on a standard tabletop.
Mini Revolution Grinder
This grinder is built for production, not pulverizing flower. You run interchangeable scalloped blade discs and variable speed control to cut cleanly. It processes up to 1 lb every 1 to 2 minutes without overheating, so you keep terp integrity and avoid turning material into dust. Stems and seeds stay intact for easier post-sifting.
That math matters. At 1 lb per 1 to 2 minutes, you’re looking at 30 to 60 lb per hour of grind capacity on the prep side.
Mini RocketBox Plus+
Once the grind looks right, you move straight into filling. The Mini RocketBox Plus+ packs up to 143 pre-rolls in under 60 seconds. Adjustable vibration lets you dial density from crutch to tip so your joints don’t come out soft in the middle and tight at the end.
One tray. One flow. Less handling.
Why this bundle wins
You get consistent particle size and consistent pack density in the same station. That’s how you stop canoe complaints before they start. One clean grind plus one consistent fill makes your smoke behave like a premium SKU, batch after batch.
Quick real-world picture: the fastest hand packer on the team sets the pace until they don’t. A machine doesn’t get tired on April 19.
Master the Finish: The Jumpstarter Bundle
Some shops fill fast and still fall behind. Closing becomes the choke point. You end up with filled trays stacked like airport luggage, waiting on a few people to twist and crown for hours.
This bundle turns your station into a true fill-to-close system.
Mini RocketBox Plus+
Same foundation here. Up to 143 pre-rolls in under 60 seconds, with a consistent pack that makes closing cleaner.
Atomic Closer Turbo
This is where your labor hours disappear in a good way. The Atomic Closer Turbo produces a Dutch Crown finish on 72 joints in under 30 seconds. Output runs up to 3,600+ joints per hour, with a shelf-ready look and a more uniform burn.
No hand cramps. No “who twisted these” mystery trays.
Why this bundle wins
Two machines can replace an entire table of closing labor during peak weeks. Your product looks the same from the first tray to the last tray. That consistency protects your brand when volume is high, and everyone is moving fast.
Here’s a simple capacity gut-check you can run today:
If you need 20,000 pre-rolls ready in 10 production days, you need 2,000 per day. When you write it down, you stop guessing. Then you build the line that hits it.
Keep the line moving: Buy 3 trays, get 1 FREE
Bundles only help if your workflow stays unbroken. That’s why both bundles run on the STM One-Tray Workflow. You move product from machine to machine without re-traying cones.
For 4/20, we’re doing a tray deal built for nonstop runs:
Buy 3 trays of any count and size, get the 4th tray free.
Mix and match to match your SKUs: 84mm, 98mm, 109mm, and Dogwalker trays. More trays mean less idle time between cycles, especially when you’re running long shifts, and your cone inventory is stacked.
One underrated win here: trays act like a buffer. When a team member steps away, the line keeps breathing.

Next step: do this one-line math
Daily target = total pre-rolls needed ÷ production days available
Once you have that daily number, the next question gets simple.
How many trays do you need to keep your filler and closer running for a full shift?
Don’t wait until the schedule gets ugly
4/20 doesn’t care about your hiring plan. If you want to protect margins, you lock in throughput early, then you let your crew focus on QA, flow, and keeping the line fed.
