Bluelab PeriPod M3 Automatic Nutrient Doser

Hands-Off Reservoir Dosing You Can Actually Trust

The Bluelab PeriPod M3 is a wall-mounted peristaltic dosing unit that responds to triggers from the Bluelab Pro Controller (sold separately) and pumps pH adjuster and nutrient stock solution straight into your tank. Manual dosing is where tanks go wrong: pH climbs overnight and plants sit in a solution that locks out iron and calcium, which surfaces as slow growth, weak roots and poor nutrient uptake a fortnight later. The PeriPod corrects drift as it happens rather than once a day when you remember. It runs 1x 120ml/min pump for pH adjuster and 2x 120ml/min pumps for nutrient stock, so it handles one-part or two-part A&B feeds, and pairs with the Pro Controller so you can watch and adjust pH and EC from a phone, tablet or PC.

Key Benefits

• Three peristaltic pumps at 120ml/min (4fl oz/min) for accurate, repeatable dosing
• Handles A&B or one-part feeds, so it suits almost any nutrient programme
• Individual pump priming and calibration keeps every line accurate
• Rugged wall-mount design keeps pumps and tubing clear of the reservoir
• Replaceable pumps and tubing, so wear parts are a quick swap
• Remote pH and EC control when teamed with the Bluelab Pro Controller
• Works with recirculating and drain-to-waste systems, including Bluelab Dosetronic models

How to Use

• Mount and plumb: fix to a wall near the reservoir and run the 4 metre acid/alkaline resistant line from the pH pump to your adjuster container.
• Nutrient lines: connect the two stock pumps using the supplied 4 metre food-grade tubing, one line per part for A&B feeding.
• Prime each pump individually before first use, then calibrate so the delivered volume matches the controller's dose request.
• Set your targets on the Bluelab Pro Controller; the PeriPod only pumps when the controller calls for a correction.
• Weekly check: top up stock containers and inspect tubing for wear.
