Hydroponics
The greenhouse hydroponic system is a soilless cultivation method that delivers water and nutrients directly to crops, promoting faster growth and higher yields.
Hydroponic system
Hydroponics is the technique of growing plants using a water-based nutrient solution rather than soil, and can include an aggregate substrate, or growing media, such as vermiculite, coconut coir, or perlite.
NFT（Nutrient Film Technique）
NFT uses slightly tilted pipes to allow a thin film of nutrient solution to flow along the bottom of the channel, continuously providing water and nutrients to plant roots while ensuring oxygen exposure. The system consists of a water pump, a nutrient reservoir, PVC pipes, support structures, and a control system.
- Nutrient Circulation – A water pump delivers the nutrient solution to the top of the pipes, allowing it to flow downward.
- Root Absorption – Plant roots partially dip into the nutrient film to absorb water and nutrients while the remaining part is exposed to air for oxygen intake.
- Gravity Return – Excess solution flows back to the reservoir for filtration and reuse.
✅ Water-efficient – Nutrient solution is continuously recycled, reducing water usage by up to 90%.
✅ Ideal for large-scale production – Modular design is suitable for mass leafy green cultivation.
✅ Prevents soil contamination, reducing disease risks.
❗ Depends on electricity – If the water pump stops, roots may dry out quickly.
Ideal for: Leafy greens (lettuce, spinach, mint) and small-root crops like strawberries.
What is a Vertical Hydroponic Tower?
- A vertical hydroponic tower is a type of aeroponic system. It delivers nutrients to plant roots using misted water.
- Compared to traditional hydroponics, aeroponic towers have several advantages. They let roots get more oxygen while using less water and fewer nutrients. This saves water, cuts costs, and reduces equipment needs.
- Aeroponic towers work well in greenhouses, especially in hot regions. They don’t need complex climate control systems. In traditional hydroponics, high water temperatures can cause root rot if cooling is not enough. Aeroponic systems avoid this problem.
- They can also grow crops that are difficult in regular hydroponic setups. This is helpful when resources are limited. Another big benefit: plants usually grow 1.5 to 2 times faster in aeroponic towers.
Large Solution Tank – The system includes a 100L nutrient solution tank, which can meet the water needs of plants throughout their entire growth cycle. The tank is equipped with wheels, making it easy to move.
Easy Installation & Leak-Proof Design – Each layer is a single integrated structure, ensuring a simple installation process and preventing leaks. The number of planting layers can be customized based on specific needs.
Higher Planting Density – Each layer contains six planting holes, offering more growing spaces than similar products. This results in higher yield per unit area.
Advantages of hydroponic towers
Balanced Nutrient Supply – The internal water flow is evenly distributed, ensuring that plant roots receive consistent nutrition. This promotes uniform crop growth.
Convenient Water Level Monitoring – The system includes a water level indicator and observation window, allowing users to easily monitor water levels at any time.
What is a Rotating Column System?
- The rotating column system utilizes a specialized low-speed rotating motor to maximize space and resource efficiency. It is both aesthetically pleasing and easy to manage.

What is a Hydroponic Ebb and Flow Seedbed?
A hydroponic ebb and flow seedbed is an efficient water-saving irrigation system named after the natural tidal phenomenon. This system originated in the Netherlands, where horticultural technology is highly advanced. It later spread to Japan, the United States, and the United Kingdom, developing rapidly and becoming a primary irrigation method for greenhouses in developed countries.
The ebb and flow system consists of four main parts:
- Ebb and flow cultivation bed
- Nutrient solution circulation system (including nutrient tank, circulation pump, and pipelines)
- Control system
- Cultivation containers (planting trays)
High Water and Nutrient Efficiency
This system uses a closed loop. It recycles water and fertilizer, reaching over 90% efficiency.Faster Growth Rate
Plants grow at least one day faster per week compared to traditional methods. This improves overall production efficiency.Improved Photosynthesis
There is no water on the leaves, so they get more light. This boosts photosynthesis and helps plants absorb nutrients better through transpiration.Stable Root Environment
The ebb and flow system keeps the roots at the right moisture and oxygen levels. It also prevents small roots from drying out at the edges of the trays.
Advantages of Flow Seedbed
Better Humidity Control
Plant leaves stay dry. This reduces the need for chemicals and keeps the plants healthier.Weed and Fungal Prevention
The area under the growing trays stays dry. This helps stop weeds and fungus from growing.Lower Labor Costs
