Horizontal pipe hydroponics is a modern soilless culture technology, using PVC pipe as the carrier, through the nutrient wave to supply nutrients and water, suitable for a variety of vegetable cultivation, saving space, increasing yield, reducing pests and diseases. Before planting, it is necessary to prepare the pipeline, seedling tray and seedling lamp. The preparation of nutrient wave is the key, and the proportion, pH and liquid temperature should be adjusted to ensure the normal growth of plants. Horizontal pipe hydroponics is a modern soilless culture technology, which uses the pipe as the carrier of plant growth and supplies the nutrients and water needed by the plant through the nutrient wave.
