Venturi Pumps vs NIDO Digital Dosing: which one should you choose to maximize greenhouse yield?

The comparison between Venturi pumps and NIDO digital dosing lies in system architecture. Venturi systems operate in line, injecting fertilizers through pressure differential, while NIDO converts a storage tank into an intelligent mixing tank. Thanks to pre-mixing and constant digital control, NIDO ensures superior stability of pH and EC parameters.


How Venturi Pumps work in in-line fertigation

Venturi pumps are mechanical injectors that work in line, exploiting the vacuum effect created by pressurized water flow to draw nutrients directly from containers and inject them into the irrigation pipeline. This system is widely used for its mechanical simplicity, as it does not require electrical power for suction and is typically installed in bypass on the main line.

However, in-line Venturi operation has structural limitations:

  • Pressure dependency: dosing varies with water flow fluctuations, making it difficult to maintain a stable EC.
  • No pre-mixing: fertilizer is injected instantly into the water stream, increasing the risk of nutrient inhomogeneity.
  • Manual management: without digital monitoring, the grower must adjust valves based on downstream manual measurements.

NIDO: the evolution of the digital mixing tank for precision agriculture

NIDO is a digital fertigation ecosystem that operates through a storage tank, transforming the water reserve into a controlled mixing environment. Unlike in-line systems, NIDO ONE V2 and NIDO Industrial sample water directly from the tank, analyze pH and EC using industrial-grade sensors, and correct the solution before it reaches the plants, ensuring absolute chemical stability.

Integrating NIDO into a farm system offers advantages unattainable by mechanical solutions:

  • Guaranteed pre-mixing: nutrients are stabilized in the tank before irrigation, eliminating toxic spikes or sudden deficiencies.
  • Flow independence: digital dosing is unaffected by irrigation pressure variations, as corrections occur in the storage tank.
  • App-based monitoring: even without push notifications, users can continuously consult historical data and real-time parameters via the App and Web Lab.

Why a storage tank with NIDO maximizes profits

Managing fertigation through a storage tank means preparing the nutrient solution in a dedicated reservoir before distribution, ensuring perfect homogeneity in every drop delivered. While in-line Venturi systems may deliver varying concentrations depending on emitter distance, NIDO’s mixing tank stabilizes the recipe upstream, guaranteeing identical nutrient supply to every plant.

This tank-based control approach allows you to:

  • Stabilize pH: acids have time to react and stabilize in the water mass before reaching the roots.
  • Optimize EC: NIDO sensors perform up to 96 checks per day, correcting even minor variations caused by evaporation or water refilling.
  • Reduce waste: digital precision eliminates overdosing, drastically reducing the cost of mineral liquid fertilizers.

Frequently Asked Questions (FAQ) about Digital Fertigation

Can NIDO work in line like a Venturi system?
No. NIDO is designed to operate with a storage tank (basin or cistern). This allows the system to sample, mix, and stabilize the solution using its algorithms, achieving a level of precision that purely in-line systems cannot reach.

What happens if internet connectivity is lost while the system is running?
NIDO guarantees offline automation through its internal processor. Once parameters are set via the App, the controller continues to monitor and correct the tank solution every 15 minutes, regardless of internet connectivity.

Which pH correctors should be used with NIDO?
To ensure sensor and pump longevity, the use of phosphoric acid (H₃PO₄) as pH- and potassium hydroxide (KOH) as pH+ is mandatory. Using different acids may damage internal components and void the warranty.

How much water can NIDO Industrial manage?
NIDO Industrial is designed to manage storage tanks from 1,000 to 100,000 liters. Its dosing power and control logic make it suitable for large greenhouse systems using open or closed-loop irrigation tanks.

Can I monitor my greenhouse in real time?
Yes. Through the NIDO App, you can check current pH, EC, and climate values at any time. Although the system does not send push notifications, active user monitoring allows full supervision of the crop from anywhere.
