Optimizing Hydroponic Plant Factories with the LANDO Nutrient Control System

In the fast-evolving world of controlled-environment agriculture, precise management of nutrient solution temperature is as critical as light, pH, and nutrient concentration. The LANDO Nutrient Control System—commonly referred to as the LANDO chiller—offers an elegant, reliable solution for maintaining optimal reservoir temperatures in hydroponic and recirculating systems. Whether you operate a large-scale plant factory or a boutique indoor farm, the LANDO chiller can help you maximize yield, improve crop quality, and prevent root-zone disorders.

The Importance of Temperature Control in Hydroponics

Water temperature directly impacts dissolved oxygen levels, root metabolism, and pathogen survival:

• Warm solution (>21 °C)

  • Dissolved oxygen declines

  • Root respiration becomes inefficient

  • Algae, Pythium, and other pathogens thrive

• Optimal range (18 °C–21 °C)

  • Maximizes oxygen availability

  • Promotes vigorous root growth

  • Suppresses disease and algae

Inconsistent temperatures can undermine even the most sophisticated nutrient-dosing and lighting strategies. By cooling the nutrient reservoir, growers maintain a stable root-zone environment that supports rapid nutrient uptake and healthy plant development.

LANDO Chiller Models & Capacities

Model	Cooling Power	Ideal Reservoir Volume
LD-1/13HP	60W	Up to 100 L
LD-1/10HP	75W	Up to 150 L
LD-1/4HP	200W	Up to 250 L
LD-1/2HP	375W	Up to 500 L
LD-2HP	1,500 W	Large-scale (>1500 L)

Each unit functions like a compact refrigeration system: 

nutrient solution is pumped in, chilled to the set temperature, and returned to the reservoir. The precise thermostat maintains setpoints to within fractions of a degree, ensuring consistent performance cycle after cycle.

Key Features & Benefits

1. Rapid Cooling Performance

   • Instant temperature reduction—equivalent to a mini-fridge dedicated to your nutrient solution.

2. Robust Construction

   • Corrosion-resistant titanium evaporator and heavy-duty steel housing ensure years of continuous operation.

3. User-Friendly Interface

   • Backlit display with three-button control makes temperature setting and monitoring effortless.

4. Auto-Protection & Safety

   • Built-in overload shutdown protects the compressor and prolongs equipment lifespan.

5. Energy Efficiency

   • Power draw ranges from just 37 W on the smallest unit to under 1.5 kW on the largest, minimizing operational costs.

Integration & Installation Best Practices

• Pump & Piping:
  Install a dedicated circulation pump and 13 mm tubing. LANDO units include barbed fittings for easy hose connection.

• Location:
  Place the chiller outside the growing chamber to prevent excess heat buildup.

• Flow Control & Filtration:
  Use an inline valve to regulate flow rate and incorporate a filter upstream of the chiller inlet to trap particulates.

• System Types:
  Compatible with DWC, RDWC, NFT, ebb-and-flow, and other recirculating hydroponic systems. Simply route the return line from the reservoir through the chiller and back.

• Ventilation:
  As with any refrigeration unit, the chiller emits heat. A small fan aimed at the unit’s heat-exchange surfaces helps dissipate warm air.

Real-World Impact

Growers who implement LANDO nutrient chillers report:

• Faster vegetative growth and stronger root systems

• Reduction in root disease incidence

• Cleaner reservoirs with minimal algae formation

• Smoother integration with automated climate and nutrient controls

Whether you run a pilot grow room or a multi-tiered vertical farm, precise root-zone temperature control is a keystone of consistent, high-quality yields.
