Soilless culture (soilless cultivation) is a cultivation method that uses substrates without natural soil or solely while seedlings are produced, followed by nutrient solution irrigation after transplanting. Because soilless culture is capable of generating a good rhizosphere environment to replace the soil environment and effectively prevent soil continuous cropping diseases and physiological disorders caused by soil salt accumulation, it can fully meet crops' nutrition requirements on mineral, water, gas, and other environmental conditions.
Furthermore, the fundamental material for cultivation may be recycled, so it has the advantages of saving water, fertilizer, and labor while producing a high yield and excellent quality. Planting holes: 6 pcs /layer.
