Groen Automation Gram Master – Automated Cannabis Weighing & Packing System

The Gram Master™ by Groen Automation is an automated cannabis packaging machine designed to streamline your post-harvest operation with legal-for-trade accuracy, fast throughput, and gentle flower handling. Built for cannabis operators who value precision, compliance, and speed, the Gram Master lets you pack more units, waste less product, and reduce labor overhead—all with one machine.

🔧 How It Works

1. Load buds into 12 top-mounted conveyors.
2. Tap the foot pedal to activate weighing sequence.
3. The system uses 12 precision load cells + an NTEP-certified final check scale to calculate the optimal drop combination with 0.01g accuracy.
4. Product is dispensed into a bag or jar by operator.
5. Second operator uses the Fill Spinner rotary table to seal and reload containers.

Whether you're packing grams, eighths (3.5g), quarters, halves or full ounces, the Gram Master offers flexible presets for all common cannabis retail formats.
