Why can a micro submersible pump be used for soilless cultivation?
Core function
The mini submersible pump drives the impeller to rotate through a motor, pumping liquid (such as nutrient solution) from the reservoir to the cultivation system to form a circulating flow.
Water circulation: ensures that the nutrient solution is evenly distributed to avoid excessive or low local concentrations.
Oxygen supply: Oxygen is naturally dissolved when the water flows in contact with the air, or oxygen is actively increased through special designs (such as gas-liquid mixers).
Technical parameters
Flow rate: usually 120-150L/h, suitable for small to medium-sized soilless cultivation systems.
Lift: 0.5-3 meters, meeting the needs of planting racks of different heights.
Power: 5-50W, low energy consumption and silent operation.

2. Specific applications in soilless cultivation
Deep flow technology (DFT)
The dc submersible pump pumps the nutrient solution into the planting trough, and the roots are directly immersed in the flowing liquid layer.
Advantages: High nutrient absorption efficiency, suitable for the rapid growth of leafy vegetables (such as lettuce and spinach).
Nutrient film technology (NFT)
The submersible pump drives the nutrient solution to flow through the planting trough in the form of a thin film, and the roots are only exposed to a thin layer of liquid flow.
Advantages: Adequate oxygen supply, reducing root diseases, suitable for crops such as strawberries and vanilla.
Aeroponic cultivation
The miniature submersible pump cooperates with the atomizer to convert the nutrient solution into tiny particles and spray them on the root system.
Advantages: Maximize the oxygen contact area, suitable for high value-added crops (such as medicinal plants).

Core advantages of micro submersible pumps
Precise control
Automatic start and stop through timers or sensors, simulating natural circadian rhythms and promoting healthy plant growth.
Energy saving and quietness
Low power design (such as 5W model) is suitable for families or small farms, and the operating noise is less than 40 decibels.
Modular design
Can be integrated with drip irrigation, spraying and other systems, and flexibly adapt to different planting needs.

Notes
Regular maintenance: Clean the mini water pump filter every 3 months to prevent algae or root blockage.
Water quality management: Use RO reverse osmosis water or replace the nutrient solution regularly to avoid salt accumulation.
Safety protection: Make sure the small water pump is completely immersed in the liquid to prevent dry burning damage.
