This utility model belongs to the field of plant cultivation technology, specifically disclosing a transparent device for hydroponic plant cultivation using a solid substrate. It includes a cultivation container with a partition dividing it into an upper and lower cultivation section. The upper cultivation section contains nutrient soil, and the lower cultivation section contains nutrient water. The partition has multiple fine holes and perforations, with cotton fibers threaded through the perforations. The ends of the cotton fibers extend to the upper and lower cultivation sections respectively. The sidewall of the lower cultivation section has through holes. This utility model separates the nutrient soil and nutrient water layers using the partition and uses the through holes to drain excess water while simultaneously creating an air barrier. During plant growth, the roots extend from the fine holes in the partition into the nutrient water in the lower cultivation section, passing through the air barrier layer. This ensures the roots receive sufficient oxygen, preventing root rot. The through holes also facilitate observation of root growth, ensuring healthy plant growth.
