question
How often does the nutrient solution need to be replaced?
For commercial NFT leaf vegetable systems, full replacement is recommended every 2–3 planting cycles. Daily monitoring of EC and pH is required, and only water and nutrients are supplemented normally between replacements.
What are the advantages of NFT hydroponic system?
Thin flowing nutrient film keeps crop roots supplied with both water, nutrition and oxygen. It effectively prevents root rot, saves water, and supports fast growth of leafy vegetables. The modular structure is easy to expand for commercial farms.
Is remote monitoring available for smart farm equipment?
Yes. The cloud control cabinet supports remote data viewing, parameter adjustment and automatic alarm push. Managers can monitor and operate the whole farm through mobile phones or computers anytime.
How to maintain stable EC and pH value in hydroponics?
Equip a water & fertilizer integrated machine with EC/pH real-time monitoring. The system automatically adds fertilizer or acid-base regulators to maintain stable nutrient solution parameters according to preset crop growth standards.
What core intelligent devices does a smart farm include?
Environmental sensors (temperature, humidity, CO₂, light intensity, EC/PH), water and fertilizer integrated machines, circulating water pumps, grow lights, ventilation, cooling and heating equipment, cloud control cabinets and surveillance cameras.
Is year-round continuous planting available?
Yes. Intelligent environmental control breaks seasonal limits to enable non-stop production all year round, unaffected by cold, heat, rain or snow.
What crops are suitable for smart soilless farms?
Recommended: Leafy vegetables (lettuce, leaf lettuce, pakchoi, coriander), strawberries, tomatoes, cucumbers, peppers, chives and other fruits and vegetables.Not recommended: Deep-rooted plants, large arbors and root vegetables such as sweet potatoes and radishes.
What are the common soilless cultivation modes?
Main types: hydroponics (deep & shallow flow), aeroponics, coco peat/rockwool substrate culture, three-dimensional pipeline cultivation and NFT nutrient film technique.
What are the differences between soilless cultivation and traditional soil cultivation?
Soilless cultivation features faster growth, higher yield, fewer pests and diseases, as well as water and fertilizer conservation. It is not restricted by land conditions. The smart version realizes largely automated operation and greatly cuts labor costs.
What is a smart soilless cultivation farm?
A modern farm that combines soilless cultivation techniques (hydroponics, aeroponics, substrate culture, etc.) with the Internet of Things, automatic control, big data and intelligent devices. It grows crops without natural soil, and intelligently manages water, fertilizer, light, temperature, humidity and ventilation throughout the process.
