The main characteristics of soilless cultivation are:

• Soil-free Environment: Using hydroponics or solid substrates (such as rockwool, coco peat) to replace soil.
• Precision Control: Precisely regulating nutrients, water, light, and temperature through automation systems.
• Efficient Resource Utilization: Reducing water and fertilizer use while enhancing resource utilization efficiency.

The advantages of soilless cultivation are:

• High Yield and Quality: Optimizing growth conditions to increase crop yield and quality.
• Water and Fertilizer Conservation: Recycling nutrient solution to reduce water and fertilizer waste.
• Pest and Disease Reduction: The soil-free environment lowers the incidence of pests and diseases, reducing pesticide use.
• High Space Utilization: Allows for multi-layered vertical cultivation, suitable for areas with limited space.
• Environmentally Friendly: Reduces soil degradation and pollution, protecting the ecological environment.

The applications of soilless cultivation include:

• Vegetable Cultivation: Such as tomatoes, cucumbers, and lettuce.
• Flower Cultivation: Such as roses and lilies.
• Medicinal Plant Cultivation: Such as mint and lavender.

Soilless cultivation in greenhouses achieves high-yield, high-quality, and environmentally friendly planting goals through precise control of plant growth conditions. It is particularly suitable for areas with limited resources or poor environmental conditions and has great potential for future applications.
