Bluelab PeriPods M3 M4 L3 | Peristaltic Dosing Pump Hydroponics Australia

Bluelab PeriPods M3, M4 & L3, Peristaltic Dosing Pumps

A PeriPod doses pH adjuster and nutrient stock solutions into your reservoir so you stop doing it by hand. It responds to electrical triggers from a Bluelab Pro Controller, which is the part that measures pH and EC and decides when a dose is needed.

You need both. A PeriPod on its own has no probes and no way of knowing what your reservoir is doing. If you don't already run a Pro Controller, budget for one alongside this.

The pumps are medical grade and can be calibrated to the viscosity of whatever you're dosing, which is what keeps flow rates consistent between a thin pH down and a thick nutrient concentrate. Pumps, cassettes and tubing are all replaceable, so the unit is serviceable rather than disposable.

Available Sizes

• PeriPod M3, $1,564.95. Three pumps. Pump 1 is set to pH by default and the other two to nutrient, though any pump can be reassigned. Suits a two-part nutrient plus pH correction.
• PeriPod M4, $2,109.95. Four pumps at the same 120ml per minute flow rate as the M3. The extra pump is for another nutrient part, not more volume. Suits a three-part programme plus pH.
• PeriPod L3, $3,809.95. Three pumps in the larger L series housing, 392mm against the M3's 220mm. Built for bigger sites and higher dosing demand.

Pick on how many separate solutions you need to dose, not on reservoir size. Every pump handles one bottle.

Chaining PeriPods

Up to three units of the same series link together, giving you a maximum of 12 pumps for a complex multi-part programme.

M and L series cannot be mixed. An M3 and an M4 chain together fine. An L3 only chains to other L3s. Worth getting right before you order, because it decides what you can add later.

Key Benefits

• Automated pH and nutrient dosing. Removes spot checks and manual adjustment, holding the reservoir at your setpoints between visits.
• Medical-grade peristaltic pumps. Solution moves through the tubing without touching the pump mechanism, so acids, alkalis and concentrates don't degrade it and nothing cross-contaminates.
• Pumps calibrate to viscosity. A thick nutrient concentrate and a thin pH adjuster don't flow the same way. Calibrating per pump is what keeps doses accurate.
• Control down to 0.1 pH and 0.1 EC. Fine enough to hold a setpoint rather than correcting after a drift.
• Replaceable pumps, cassettes and tubing. The wearing parts come out, so the unit stays in service.
• Opaque nutrient tubing. Blocks light, which stops algae growing inside the lines.
• Fan-cooled and wall-mounted. Quiet in a room and out of the way.
• Can sit below the injection point. The pumps lift solution, so mounting height is flexible.

How It Works

• The Pro Controller measures your reservoir. Its probes read pH and EC continuously against the setpoints you've configured.
• It sends a dosing trigger to the PeriPod. An electrical signal, not a measurement. The PeriPod does no sensing of its own.
• The pump runs for a calculated time. Rollers compress the tubing and push solution through, with volume set by run time against the calibrated flow rate.
• Solution enters the reservoir. Inlet tubes sit in your stock bottles, outlet tubes in the tank.
• The controller re-reads and stops when in range. Dosing continues in increments rather than one large correction.

What's in the Box

• 4 metres of acid and alkali resistant tubing for pH adjuster
• 4 metres of opaque food-grade nutrient tubing per nutrient pump
• 24V DC power supply
• Dosing cable and mounting screws

Ideal For

• Growers already running a Pro Controller. This is the dosing half of that system, and the reason to have bought the controller.
• Multi-part nutrient programmes. One pump per bottle, so a three-part plus pH needs four pumps.
• Recirculating and drain-to-waste systems. Both are supported. It is not an inline doser and shouldn't be plumbed as one.
• Sites where nobody is on hand daily. The value is in what happens to your reservoir on the days you don't visit.

Bluelab PeriPods are peristaltic dosing pumps for the Bluelab Pro Controller, available in three and four pump configurations for automated multi-part nutrient and pH delivery.

Frequently Asked Questions

Do I need a Bluelab Pro Controller as well?

Yes. The PeriPod is a pump and nothing more. It has no probes and can't measure your reservoir. The Pro Controller does the measuring and sends the dosing trigger, and it's sold separately. Buying a PeriPod on its own leaves you with a pump that has nothing telling it when to run.

What's the difference between M3, M4 and L3?

The number is how many pumps you get. M3 has three, M4 has four at the same flow rate, so the fourth pump is for another nutrient part rather than extra volume. L3 is the larger L series with three pumps, physically bigger at 392mm against the M3's 220mm, for higher demand sites.

How many pumps do I actually need?

One per bottle you want dosed. A two-part nutrient plus pH down is three pumps, so an M3. A three-part plus pH is four, so an M4. Count your bottles, not your litres.

Can I link an M3 and an L3 together?

No. M series chains to M series and L3 chains only to other L3s. You can link up to three units of the same series for a maximum of 12 pumps. Decide which series you're on before you buy the first one.

What nutrients can I run through it?

Most liquid mineral, chelated and organic formulas. Pumps calibrate to the viscosity of what they're dosing, so thick concentrates are handled. Avoid pure oils and heavy organic teas with solids in them, and flush the lines with clean water when changing products.

Can I mount it above the reservoir?

The unit can sit lower than the injection point, so mounting height is flexible. It's wall-mounted and fan-cooled. It isn't designed to be plumbed inline.

Does it qualify for free shipping?

Yes. All three configurations clear the $150 threshold comfortably, so they ship free to VIC, NSW, QLD, SA and ACT. WA, NT, Tasmania and remote areas are quoted separately.
