Bluelab PeriPod M4 for Pro Controller

Automatic pH and Three-Part Nutrient Dosing, 4 Pumps at 120 ml/min

Mixing multi-part nutrients and correcting pH by hand is slow and hard to repeat batch after batch. The PeriPod is the dosing half of a Bluelab Pro Controller system: the controller measures the reservoir and the PeriPod's peristaltic pumps dose pH adjusters and nutrient stock solutions as needed. Set individual nutrient ratios in the Edenic app.

With four pumps defaulting to pH plus nutrients A, B and C, the M4 handles three-part feeds or a two-part feed with an additive. It suits home and small to mid-size commercial reservoirs.

Key Features & Benefits

• 4 pumps at 120 ml/min — each pump can be configured for pH or nutrient delivery.
• Linkable — connect multiple PeriPods for complex schedules, up to 12 pumps.
• Quiet and fan-cooled — compact, wall-mounted design that can sit lower than the injection point.
• Viscosity calibration — individual pump priming and calibration for each nutrient.
• Algae-resistant tubing — opaque nutrient tubing limits light in the lines.

Who Should Use the PeriPod M4

Growers running a Pro Controller Wi-Fi with three-part nutrients, or a two-part feed plus an additive, alongside pH correction.

About Bluelab PeriPod M4

The PeriPod M4 ships with a getting started guide, 4 m of acid/alkaline-resistant tubing for pH dosing and 3x 4 m lengths of food-grade nutrient tubing. It runs on a 24 V DC power supply and carries a 2-year limited warranty (6 months on cassettes and tubing).

Frequently Asked Questions

Which controller do PeriPods work with?

PeriPods are dosers for the Bluelab Pro Controller Wi-Fi (BCTPRC02) and the earlier Pro Controller (CONTPRO). The controller measures the reservoir and tells the PeriPod when and how much to dose.

Can I mix PeriPod M and L models?

No. PeriPod M3 and M4 units cannot be connected on the same system as a PeriPod L3. Choose one series to match your reservoir size and link up to 12 pumps.

What is a peristaltic pump?

A peristaltic pump moves liquid by squeezing a flexible tube with rollers, so the solution only touches the tubing. That makes it accurate and well suited to concentrated nutrients and pH adjusters. Bluelab rates PeriPod flow accuracy at ±10% at 25°C / 77°F.

Do the pumps need calibration?

Calibration is not required, but each pump has a calibration feature so you can match it to the viscosity of the nutrient it doses. Individual priming is also supported.

Which acids can the tubing handle?

As a guide, Bluelab lists acid concentrations of less than 80% phosphoric, 35% nitric, 30% sulfuric or 20% citric acid by volume for PeriPods. Test tubing with your specific chemical before relying on it.
