Getting started

General questions about GrowDirector 4 PRO, demos, purchasing, scalability, and where the system can be used.

Can I get a demo of GrowDirector 4 PRO?

Yes. You can explore the built-in demo in the GrowDirector App or contact our team to schedule a demonstration and discuss your greenhouse or growing facility.

We can walk you through the system, show how the modules work together, and help determine which configuration fits your operation.

The current App page explicitly offers the built-in demo and remote system demonstration. growdirector.com

Why should I choose GrowDirector 4 PRO?

GrowDirector is designed to bring monitoring, automation, and equipment control into one connected system.

Key benefits include:

  • Greenhouse automation: automate irrigation, fertigation, climate, lighting, and connected equipment.
  • Remote control: monitor and manage your operation through the GrowDirector App.
  • Data-driven decisions: use real-time sensor data instead of relying only on manual checks.
  • Reduced manual work: automate repetitive routines and equipment operation.
  • Scalability: start with the modules you need and expand the system as your operation grows.
  • Flexible equipment integration: connect pumps, fans, heaters, chillers, valves, lighting, and other greenhouse equipment.
Where can I buy GrowDirector equipment?

GrowDirector equipment is available through our network of authorized distributors.

Our partners can assist with product availability, quotes, delivery, installation, and local first-line support.

If there is no distributor in your region, contact GrowDirector and we will help you with the next steps. The current distributor page lists partners by region and explicitly describes local supply and support.

Can I expand my GrowDirector system later?

Yes. GrowDirector is designed as a modular system.

You can start with the modules needed for your current operation and add additional modules as your greenhouse or facility expands. New modules connect to the same network and can be configured through the app.

Hydroponics & fertigation

Questions about nutrient dosing, water-quality monitoring, pumps, and hydroponic automation.

Is GrowDirector suitable for hydroponics?

Yes. HydroDirector is specifically designed for hydroponic and fertigation automation.

It can continuously monitor and control key water parameters such as pH, EC, and water temperature, and automate nutrient dosing according to your configured targets. growdirector.com

How many dosing pumps can I connect?

GrowDirector is designed to scale from the dosing pumps integrated with HydroDirector to much larger installations using additional control modules and external pumps.

For larger dosing systems, pumps can be integrated through SocketDirector or DryContactDirector depending on the electrical and control requirements.

For a commercial installation, we recommend confirming the required number, flow rates, and pump configuration with our team before ordering.

I prefer this answer over carrying the old FAQ's very specific 48,000 devices wording into the new page. The current HydroDirector page focuses on scalable pump integration rather than presenting that number as the primary specification.

What size water reservoir can GrowDirector handle?

The practical reservoir size depends primarily on the dosing equipment, required flow rates, irrigation design, and how quickly the system needs to make corrections.

HydroDirector can work with its integrated dosing pumps, while larger pumps can be controlled through SocketDirector or DryContactDirector.

For large commercial reservoirs, contact our team with your reservoir capacity, required flow rates, and fertigation setup so we can recommend the appropriate configuration.

Monitoring & equipment control

Learn what GrowDirector can monitor, automate, and control throughout a growing facility.

What can GrowDirector monitor and control?

GrowDirector can bring environmental monitoring and equipment automation into one system.

Depending on your configuration, you can monitor parameters such as:

  • Air: temperature, humidity, VPD, and CO₂
  • Water: pH, EC, temperature, and other supported water parameters
  • Soil/substrate: moisture and related sensor data
  • Light: PAR and LUX
  • Other supported environmental and process measurements

The system can then use sensor readings, schedules, rules, and automation logic to control connected equipment.

What equipment can be connected to GrowDirector?

GrowDirector can control a wide range of greenhouse and cultivation equipment, including:

  • irrigation pumps
  • dosing pumps
  • circulation and ventilation fans
  • heaters
  • chillers
  • air conditioners
  • humidifiers and dehumidifiers
  • irrigation and solenoid valves
  • lighting
  • compressors
  • other compatible electrical equipment

For standard plug-in equipment, SocketDirector provides individually controlled AC sockets. For relay-controlled or higher-power equipment, DryContactDirector provides dry-contact switching.

Can GrowDirector control both high-power and low-voltage equipment?

Yes. The appropriate module depends on the equipment.

SocketDirector is intended for compatible plug-in AC equipment, while DryContactDirector provides independent dry-contact relay channels for equipment and control circuits requiring external switching.

DryContactDirector supports both AC and DC relay applications, which makes it suitable for a wide range of greenhouse equipment and control systems. growdirector.com

11. Where can GrowDirector be used?

GrowDirector can be used in many controlled-environment agriculture applications, including:

  • commercial greenhouses
  • hydroponic facilities
  • indoor farms
  • container farms
  • nurseries
  • soil-based growing
  • vertical growing
  • research and development facilities

The modular architecture allows the system to be configured around the growing method and equipment used at each site.

Connectivity

How GrowDirector modules connect, communicate, and scale across your operation.

How does GrowDirector's wireless connectivity work?

GrowDirector modules communicate through the site's Wi-Fi network.

There is no need to run communication cables between greenhouse zones. A module can be installed where it is needed, connected through the GrowDirector App, and added to the same network as the rest of the system.

The site's router itself can use either wired internet or a cellular connection, which also makes the system suitable for remote locations. See Connectivity for the current setup process.

Do I need wired internet at the greenhouse?

No. The GrowDirector modules need access to the router's Wi-Fi network, but the router itself can connect to the internet through either a normal wired connection or compatible cellular internet.

For remote greenhouse locations, a cellular router with a SIM/data connection can therefore be used.

What happens if the internet connection is unavailable?

Remote cloud access and remote monitoring require an internet connection.

If internet continuity is critical to your operation, we recommend using a reliable router, considering a cellular backup connection, and discussing your required failover behavior with the GrowDirector team during system design.

I would use this wording rather than copying the old FAQ's unconditional claim that everything will always continue working exactly the same during an outage, because the current public connectivity documentation does not make that guarantee.

App & remote access

Questions about notifications, remote monitoring, automation rules, and system management.

What can I do from the GrowDirector App?

The GrowDirector App is the central interface for the system.

You can use it to:

  • monitor greenhouse conditions in real time
  • control connected equipment
  • configure automation
  • set up and connect modules
  • review system data
  • manage irrigation, fertigation, climate, and lighting
  • access your operation remotely

The current platform is designed so monitoring, automation, and control are managed from the same application.

What notifications can GrowDirector send?

Notifications can be used to alert you when important conditions or system states require attention.

For example, alerts can be configured around critical parameter changes such as temperature, humidity, water conditions, or other monitored values.

Notifications help you respond to changes without continuously checking the system manually. Current product pages specifically describe notifications for critical parameter changes.

Can I monitor GrowDirector from a computer as well as my phone?

Yes. GrowDirector is designed for remote monitoring and management from your phone, tablet, or computer.

This allows you to check the operation and respond to changing conditions even when you are away from the greenhouse.
