Rolling benches are a very popular hydroponic system for greenhouses. The hydroponic irrigation method used is usually ebb and flow system ( also named flood and drain system ), that is through regular bottom water fertilization to ensure adequate nutrient supply while reducing water consumption by at least 33%, and reduce the amount of nitrogen used by 30%-35%, increase the water utilization rate by more than 40%.
Then through the circulation system to further increase the utilization rate of water and fertilizer.
With the hydroponic bucket system, it can form a growing system for large plants, or it can be combined with the hydroponic tray to form a sprouting system for seedlings.
This hydroponic system is suitable for all kinds of plants, such as leafy vegetables, herbs, large plants (tomatoes, watermelons, cucumbers, peppers, etc.), and various bucket plants, etc.
Even so, the labor cost required is very small, but the output is amazing, especially the advantages of planting vegetables are very obvious.
