Bluelab Peripod M4 120ml/min

Manual reservoir management, spot-checking pH and EC, then adjusting by hand, works fine at small scale, but it becomes a genuine labour cost as system size and reservoir count increase. The Bluelab PeriPod is a peristaltic dosing system designed to automate that process entirely, maintaining stable pH and nutrient levels in a reservoir without requiring manual intervention. Paired with the Bluelab Pro Controller Wi-Fi, it responds directly to real-time pH and EC readings, dosing pH adjusters and nutrient stock solutions as needed to keep conditions in the target range continuously.

Each PeriPod channel uses a medical-grade peristaltic pump, the same pump technology used in precision medical dosing applications, for long-lasting accuracy and consistent flow rate. Pumps can be individually calibrated to the viscosity of the specific nutrient or stock solution running through them, meaning dosing accuracy holds even when running products of differing thickness side by side. Adjustments can be fine-tuned in increments as small as 0.1 pH and 0.1 EC. Multiple PeriPods can be linked together to build complex multi-part nutrient schedules, with a maximum of 12 pumps able to run from a single system, and the included Edenic app allows individual nutrient ratios to be set and managed remotely.

Practical design details support long-term reliability: opaque nutrient tubing prevents algae growth inside the lines, the doser can be positioned lower than the injection point without affecting performance, and the pump cassettes and tubing are fully replaceable, extending the working life of the unit well beyond what a sealed, non-serviceable doser would offer. Designed and assembled in New Zealand. Requires a Bluelab Pro Controller Wi-Fi to operate. Wall-mounted design, quiet and fan-cooled.

This model has four dosing channels with a flow rate of up to 120 ml per minute per pump, suited to small to medium commercial systems requiring an additional dosing channel over the M3. Note: PeriPod M4 cannot be connected with a PeriPod L3.
