Inline Dosing

Continuous feeding, injected straight into your irrigation line.

Feed as the water flows

Fast dosing, backed by real intelligence.

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.

Built for commercial scale

With our 2-inch commercial doser, deliver 60+ gallons per minute with no issues. One Elixir Ultra holds a 1:100 injection ratio at full flow, and you can multiply that by stacking pumps: up to six Elixir Ultras per unit. Valves, sensors, and injectors come as one fully integrated system, so it runs completely automatically with as many recipes as you need.

Not sure which dosing method fits?

Tell us about your crop, your zones, and your water, and our engineers will help you choose between inline, batch, and recirculating dosing, and size the system around it.

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 during the same fill 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 in a multi-step process, then delivers it. Inline dosing skips the tank and meters nutrients straight into the flowing line in a single step, so feed is made on demand as plants are watered. The Aurora II does both, so you can choose per zone, and inline is the faster choice when your feeding windows are tight.

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.

How does inline dosing stay accurate as flow changes?

Flow and dosing are separate systems on the Aurora II. A flow meter reads the real rate passing through the line, and the controller computes the dose from that reading, so the feed ratio holds steady even as flow speeds up or slows down.

Do I need a reservoir tank to run inline dosing?

No. Inline dosing injects directly into the water line as it flows, so there's no reservoir to plumb, size, or find floor space for. That makes it a good fit for propagation rooms and other height-constrained spaces where a batch tank won't fit.

What equipment do I need for inline dosing?

An Aurora II controller, at least one Elixir pump module to inject nutrient, and inline pH and EC sensors on the line. Larger systems add venturi injectors, which use the line's own pressure to inject without bleeding off pressure. The Aurora II coordinates the pumps, sensors, and valves to hold your recipe automatically.

Does inline dosing work at small and large scale?

Yes. A 1-inch system with a wall of nutrient jugs and two Elixir II pumps suits propagation houses and smaller greenhouses. A 2-inch commercial system with Elixir Ultra pumps delivers 60+ gallons per minute for large greenhouses, multi-zone boom irrigation, and continuous-flow operations feeding open fields.

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.
