DWC (Deep Water Culture) is a hydroponic method that completely immerses plant roots in nutrient rich aqueous solutions. This system is also known as a raft system, as plants float on the water surface in a raft like system. The core of the DWC system is to suspend plant roots in nutrient solution, providing them with permanent nutrients, water, and oxygen.
DWC systems typically consist of a deep reservoir and a net pot. The net pot is suspended above the nutrient solution, and the roots of the plant are completely submerged in the solution. To ensure sufficient oxygen supply to the roots, an air stone connected to an air pump is usually added at the bottom of the reservoir, which helps circulate nutrient solution and supply oxygen through bubbles.
DWC (Deep Water Culture) is the preferred system of choice for growing leaf lettuce, which are very fast growing and water loving plants, making them an ideal choice for the DWC hydroponic system. Many commercial hydroponic lettuce operations employ this method, using floating Styrofoam rafts to hold the plant cups or just the plants themselves.

| features and advantages: | - Economical: The DWC system consumes less water and has low maintenance costs. - Easy to install: suitable for beginners, with relatively simple installation and maintenance - Fast growth rate: Due to the high oxygen and nutrient rich solution, the growth rate of plants is faster than planting in ordinary soil. | The advantages of RDWC hydroponic system mainly include high efficiency, environmental protection, labor saving, and automated control. |
| application: | for growing leaf lettuce, which are very fast growing and water loving plants | The RDWC hydroponic system is suitable for growing a variety of plants, including lettuce, kale, spinach, and tomatoes. These plants grow well in hydroponic systems, with low nutrient requirements and suitable growth conditions. |
This hydroponic system can be as simple as a bucket full of mixed hydroponic nutrients with a hole in the lid to support a net pot or it can be made large enough to support multiple plants. DWC hydroponics requires nothing more than a simple air stone and air pump to keep the nutrient solution stirred, oxygenated and fresh.
Economical: The DWC system consumes less water and has low maintenance costs.
Easy to install: suitable for beginners, with relatively simple installation and maintenance
Fast growth rate: Due to the high oxygen and nutrient rich solution, the growth rate of plants is faster than planting in ordinary soil. For example, lettuce can be harvested within 30 days, while it takes about 60 days in soil.
Sets of DWC hydroponic system include: 20L Buckets, Net cups, Nutrient pump, Air hose, Air stone, Air low adjustable valve, Ring drip irrigation set, Water level and drainage fitting, Main pipe with accessories
RDWC (Recirculating Deep Water Culture ) hydroponic Systems is an improved version of DWC (Deep Water Culture) systems, allowing plants to receive unlimited amounts of nutrients. A method used to grow plants with the roots submerged in a highly oxygenated nutrient solution.
By using RDWC System, you can optimize your plants maximum growth potential due to the super oxygenated nutrient solution that is constantly re-cooling and mixing the nutrients.
With high volume of water that is contained and circulated in the system PH and EC levels are continuously.
Sets of RDWC hydroponic system include: 27L Grow buckets, Main supply bucket, Net cups, Nutrient pump, Air hose, Clay pebble, Water level floating fitting, Cycle and water pump, Air stone, Main pipe, Shut off valve, (Water chiller)
Efficiency: The RDWC hydroponic system supplies liquid fertilizer to plant roots through droppers, providing a balanced supply of water, oxygen, and fertilizer, allowing plants to grow at lower pressures, thereby increasing root activity and improving yield and quality.
Environment friendly: The RDWC hydroponic system is designed to recycle the water and nutrient solution, reducing water waste. Excess water in the system is collected and recycled, reducing evaporation and waste.
In addition, by not using base fertilizer, it can reduce soil and water pollution caused by excessive fertilization.
Labor saving: The RDWC hydroponic system achieves precise environmental regulation and nutrient supply through automated control equipment, reducing manual labor intensity. Liquid fertilizer is automatically supplied through droppers, eliminating the need for frequent watering or fertilization, thus saving a lot of time.
Automated control: The RDWC hydroponic system can be equipped with automated control equipment to automatically determine watering and fertilization amounts based on crop growth, reducing manual intervention and improving planting efficiency.
