Substrate
The greenhouse hydroponic system is a soilless cultivation method that delivers water and nutrients directly to crops, promoting faster growth and higher yields.
Greenhouse Substrate Cultivation System
Substrate cultivation is a soilless growing method where plant roots are anchored in artificial substrates instead of soil. Common substrates include coconut coir, rockwool, perlite, and expanded clay, which provide water retention, aeration, and structural support for healthy root development.
Nutrients and water are supplied through drip irrigation or other fertigation systems, ensuring precise nutrient delivery. This method allows better resource efficiency, higher yields, and reduced soil-borne diseases compared to traditional soil-based cultivation.
- Precise Nutrient and Water Management
- Reduced Risk of Soil-Borne Diseases
- Higher Yields and Improved Crop Quality
- Sustainability and Eco-Friendliness
Bag Culture
Plants are grown in substrate-filled grow bags with drainage holes at the bottom. Nutrient solutions are delivered via drip irrigation to support plant growth.
✅ Easy management – Simple setup and replacement, ideal for tomatoes, cucumbers, and strawberries.
✅ Efficient water use – Precision irrigation improves nutrient absorption.
✅ Scalable for large production – Easily adaptable to greenhouse layouts.
❗ Drainage must be optimized to prevent root rot.
Gutter System
Plants are grown in substrate-filled gutters that allow nutrient delivery via drip or sub-irrigation. Excess nutrient solution can be collected and reused.
✅ Nutrient recycling – Unused nutrients are collected for reuse.
✅ Good drainage – Reduces disease risk, suitable for fruiting vegetables like tomatoes and peppers.
✅ Modular design – Works well in automated greenhouse operations.
❗ Regular flushing required to prevent salt buildup.
Rockwool Culture
Plants are grown in rockwool blocks or slabs, which provide excellent moisture retention and aeration. Nutrient solutions are delivered via a drip irrigation system.
✅ High water retention – Reduces irrigation frequency.
✅ Inert and clean – Rockwool does not release harmful substances.
✅ Suitable for dense planting – Increases yield per square meter (e.g., tomatoes, cucumbers, and lettuce).
❗ Non-biodegradable – Requires proper disposal to minimize environmental impact.
Coconut Coir Culture
Plants are grown in coconut coir-filled bags or containers. The material provides high water retention and aeration, with nutrients supplied through a drip irrigation system.
✅ Eco-friendly and biodegradable – A sustainable alternative to rockwool.
✅ Excellent moisture retention – Reduces water loss, ideal for dry regions.
✅ Versatile application – Suitable for tomatoes, strawberries, bell peppers, etc.
❗ Requires EC monitoring – Prevents salt accumulation from affecting plant growth.
