Maintaining the right nutrient concentration and pH level is one of the most important aspects of successful hydroponic growing. Even minor fluctuations can affect nutrient uptake, slow plant growth, and reduce yields.
Two popular solutions used by hydroponic growers are Growee and Dosatron. While both help automate nutrient delivery, they use completely different technologies. Dosatron relies on mechanical water-pressure injection, while Growee uses sensors and smart automation to monitor and adjust water chemistry in real time.
So which system is right for your grow?
This guide compares Growee and Dosatron, explains how each system works, and helps you decide which solution best fits your hydroponic setup.

What Is Growee?
Growee is a smart hydroponic automation system designed to monitor and manage nutrient levels and pH automatically.
Using EC and pH sensors placed directly in the reservoir, Growee continuously checks water conditions and makes adjustments whenever values move outside the desired range.
The system can:
- Monitor EC levels in real time
- Monitor pH levels continuously
- Automatically dose nutrients
- Automatically add pH Up or pH Down
- Send alerts and data through a mobile app
- Reduce manual testing and adjustments
Growee is particularly useful for recirculating hydroponic systems where nutrient concentrations constantly change as plants absorb water and nutrients.
What Is Dosatron?
Dosatron is a mechanical fertilizer injector powered entirely by water pressure.
Installed directly into an irrigation line, it automatically mixes concentrated nutrients into water at a predetermined ratio whenever water flows through the system.
Unlike smart controllers, Dosatron does not measure nutrient levels or pH.
Instead, it injects nutrients at a fixed ratio regardless of what is happening in the reservoir.
Dosatron is widely used in:
- Commercial greenhouses
- Irrigation systems
- Run-to-waste hydroponic operations
- Agricultural applications
Because it operates without electricity, Dosatron is valued for its simplicity and reliability.
How Growee and Dosatron Work
Growee’s Smart Dosing System
Growee uses a closed-loop automation process:
- Sensors measure EC and pH.
- The system compares readings to target values.
- Dosing pumps activate only when corrections are needed.
- Once targets are reached, dosing stops automatically.
This continuous monitoring helps maintain stable growing conditions around the clock.
Dosatron’s Mechanical Injection System
Dosatron uses an open-loop process:
- Water flows through the injector.
- Nutrient concentrate is drawn into the water stream.
- Nutrients are injected at a preset ratio.
- The system continues injecting regardless of actual EC or pH levels.
Because no measurements are taken, growers must manually test and adjust their solution when needed.

Understanding Open-Loop vs Closed-Loop Dosing
One of the biggest differences between these systems is how they respond to changing reservoir conditions.
Open-Loop Dosing
An open-loop system performs an action without checking the outcome.
Dosatron injects nutrients at the selected ratio every time water passes through the unit. It does not know if nutrient levels are too high, too low, or exactly where they should be.
As plants consume nutrients, reservoir conditions change, but Dosatron continues dosing exactly the same way.
Closed-Loop Dosing
A closed-loop system constantly measures conditions and adjusts accordingly.
Growee continuously monitors EC and pH levels. If readings drift outside the desired range, corrective dosing occurs automatically.
This helps maintain more stable nutrient availability throughout the grow cycle.
Why EC and pH Control Matter
Healthy plants depend on consistent nutrient availability.
Importance of EC
Electrical Conductivity (EC) measures nutrient concentration in the water.
If EC becomes too low:
- Nutrient deficiencies may occur
- Growth can slow down
If EC becomes too high:
- Plants may experience nutrient burn
- Water uptake may decrease
Importance of pH
pH determines how effectively roots can absorb nutrients.
When pH drifts outside the ideal range:
- Nutrient lockout can occur
- Deficiency symptoms may appear
- Plant performance may decline
Maintaining stable EC and pH levels helps maximize plant health and yield potential.
Benefits of Using Dosatron
Dosatron remains a popular choice because of its simplicity.
Advantages
- No electricity required
- Durable mechanical design
- Reliable nutrient injection
- Ideal for greenhouse irrigation

These features can save time while helping maintain optimal growing conditions.
Which System Is Best for Your Grow?
Choose Dosatron If:
- You operate a run-to-waste system.
- You prefer simple mechanical equipment.
- You have limited electrical access.
- You already use commercial irrigation infrastructure.
- You do not mind manual water testing.
Choose Growee If:
- You run DWC, RDWC, or NFT systems.
- You want automatic pH control.
- You want real-time EC monitoring.
- You travel frequently.
- You want remote monitoring through an app.
- You want less daily maintenance.
Final Verdict
Both Growee and Dosatron can improve nutrient management, but they serve different types of growers.
Dosatron is a reliable mechanical injector that excels in simple irrigation setups and large-scale operations where fixed-ratio nutrient injection is sufficient.
Growee offers a more advanced approach by actively monitoring reservoir conditions and making automatic adjustments when needed. This closed-loop technology helps maintain stable EC and pH levels, making it particularly valuable for recirculating hydroponic systems.
For growers seeking precision, automation, and real-time control, Growee provides significantly greater oversight of nutrient management. For those prioritizing simplicity and water-pressure operation, Dosatron remains a dependable choice.
Frequently Asked Questions (FAQs)
Can Growee replace a Dosatron?
In many hydroponic setups, yes. Growee can manage nutrient dosing automatically while also monitoring EC and pH levels. However, commercial irrigation systems designed around inline injection may still prefer Dosatron.
What is the main difference between Growee and Dosatron?
Growee uses sensors and automated feedback to adjust nutrient levels, while Dosatron injects nutrients at a fixed ratio without monitoring water conditions.
Does Dosatron control pH?
No. Dosatron only injects nutrient solution. pH monitoring and adjustment must be done manually.
Does Growee automatically adjust pH?
Yes. Growee can automatically add pH Up or pH Down when readings move outside the target range.
Which system is better for DWC and RDWC?
Growee is generally better suited for Deep Water Culture (DWC) and Recirculating Deep Water Culture (RDWC) because it continuously monitors changing reservoir conditions.
Does Growee require regular maintenance?
Yes. EC and pH probes should be cleaned and calibrated periodically to maintain accurate readings.
Does Dosatron require electricity?
No. Dosatron operates entirely using water pressure and does not need electrical power.
Is Growee worth it for home hydroponic growers?
