Inline Dosing

Continuous feeding, injected straight into your irrigation line.

Feed as the water flows

Inline, batch, or recirculating. One controller does all three.

What is inline dosing?

Inline dosing injects nutrients directly into your irrigation line as water flows to your plants, so every feed is mixed fresh and delivered on demand. There is no large batch tank to fill and wait on, and live pH and EC readings let the system correct the solution in real time as it runs.

The Aurora II drives the whole process: Elixir pumps inject each nutrient into the line, inline sensors read the result, and the controller holds your recipe automatically. The same controller also runs batch and recirculating dosing, so you can pick the method that fits each zone, or mix them, without changing hardware.

Nutrients injected as the water flows

An Aurora II and its Elixir pumps meter each nutrient straight into the irrigation main while inline sensors track pH and EC in real time. Run pH Up, pH Down, and any ratio of nutrients, and let the controller hold your target feed continuously, zone by zone, with no manual mixing.

Inline dosing, built to scale

Start with a wall of nutrient jugs and a single Aurora II, then grow into a row of IBC totes feeding a whole facility, all on the same controller. With up to 18 dosing pumps, 20 valve outputs, and flow, pressure, and level sensing, one Aurora II scales your inline system from a single room to a commercial operation.

Frequently asked questions

What is inline dosing?

Inline dosing injects nutrients directly into the irrigation line as water flows to your plants, for continuous, on-demand feeding. The solution is mixed fresh in the line and corrected in real time from live pH and EC readings, with no separate batch tank.

How is inline dosing different from batch dosing?

Batch dosing mixes a full tank to your recipe and then delivers it. Inline dosing skips the tank and meters nutrients straight into the flowing line, so feed is made on demand as plants are watered. The Aurora II does both, so you can choose per zone.

What equipment do I need for inline dosing?

An Aurora II controller, at least one Elixir II or Elixir Max pump module to inject nutrient, and inline pH and EC sensors on the line. The Aurora II coordinates the pumps, sensors, and valves to hold your recipe automatically.

Can the same controller also do batch and recirculating dosing?

Yes. The Aurora II runs inline, batch, and recirculating dosing, and you can mix methods across zones without changing controllers.

Does inline dosing work at small and large scale?

Yes. The same Aurora II runs a compact setup with a wall of nutrient jugs and scales up to a row of IBC totes feeding a full facility, with up to 18 dosing pumps and 20 valve outputs.

How accurate is inline dosing?

Lab-grade pH and EC sensors read the line in real time, and the Aurora II's dosing algorithm meters nutrient in fine increments, so the feed stays on target as flow and water chemistry change.
