In a DWC system:
Plants are placed in net pots filled with a growing medium like hydroton or clay pebbles.
The roots hang directly into a reservoir filled with a nutrient solution.
An air pump connected to air stones constantly oxygenates the water to prevent root rot and ensure healthy growth.
The roots absorb nutrients and water directly, promoting rapid growth.
Faster Growth: Constant access to oxygen and nutrients accelerates plant growth.
Water Efficient: Uses less water compared to traditional soil methods.
Reduced Pests & Diseases: No soil means fewer pests and soil-borne diseases.
Easy Maintenance: Simple setup and minimal daily effort.
Great for Beginners & Experts: Scalable from small home units to commercial systems.
To build a DWC system, you’ll need the following:
Reservoir – Holds the nutrient-rich water solution.
Net Pots – Hold the plants and allow roots to grow downward.
Growing Medium – Clay pebbles or hydroton to support the plant in the net pot.
Air Pump & Air Stones – Provide oxygen to the roots by bubbling air through the water.
Nutrient Solution – A balanced hydroponic fertilizer mix.
pH Meter & EC Meter – For measuring acidity and nutrient concentration in water.
This system is best suited for lightweight, fast-growing plants such as:Lettuce
Spinach
Basil
Kale
Swiss Chard
Strawberries
Herbs (like cilantro, mint)
Tomatoes (with support)
Check pH levels regularly (ideal range: 5.5 – 6.5).
Change the nutrient solution every 1–2 weeks.
Clean the reservoir and air stones to prevent algae or bacteria build-up.
Keep water temperature between 18°C to 22°C.
Ensure proper oxygenation 24/7 using a reliable air pump.
DWC is used in both home gardening and commercial farms because of its simplicity and effectiveness. Home gardeners use it for growing leafy greens and herbs on balconies or rooftops, while commercial growers use large-scale DWC systems to cultivate vegetables in climate-controlle
