iGrow 1800 - iDoser Nutrient Controller Overview

The iDoser represents the latest in nutrient control technology.

It interfaces the iGrow 1800 for local programming and control and consists of up to eight injectors feeding a manifold where the nutrients and/or acid/base are injected into the water stream drawn from the tank and back to the tank. The water in the tank is constantly being mixed to ensure a uniform mix.

 

Electro-conductivity (EC) and pH sensors are continuously monitoring the nutrient level and acidity of the water. This data is read by the iDoser which then controls the injectors to drive the EC and pH values to their targets.  Water is drawn out from the tank to irrigate the grow areas based on the schedules programmed in the iGrow 1800.

With the iDoser you can do Batch Mode:

 

With the iDoser you can do Re-circulation Mode:

 

The iGrow 1800 controller can also be interfaced with a computer which has the LinkConn software.
This LinkConn software allows for a very modern graphical interface that is easy to program and provides extensive historical data and graphing capabilities. It can interface with the LinkConnTM cloud monitoring and alert system as well as providing for additional data storage.

 

Some of the key features of the iDoser are summarized below:
• Up to eight separate independently controllable ingredients can be supported
• Nutrients can be injected independently or based on a ratio with respect to another nutrient
• Up to eight separate tanks with unique mixed formulations can be supported.
• Basic package includes 16 programmable relay outputs

 

In addition to controlling nutrients and pH of water, the iDoser/iGrow 1800 is also capable of environmental control. For example, it can control on/off equipment such as heaters, fans, louvers. It can control irrigation and misting valves and it can control lights for supplementary and photo periodic lighting. Finally, with an optional CO2 monitor it can control CO2 injectors.

This manual focuses on the iDoser and how it is programmed via the LinkConnTM software. A separate manual covers the programming of the iGrow 1800.
