A ebb and flow rolling bench (tidal seedbed) is a versatile growing system capable of supporting a wide range of crops. This hydroponics technique, also known as the flood-drain method, maintains crops by periodically flooding trays with nutrient-rich water. Crops are suspended in the trays and roots are submerged in the nutrient-rich water as it floods, ensuring that the plants receive adequate nutrition. With the Tidal Ebb and Flow hydroponic system, growers can easily grow healthy crops.
Standard specifications for rolling benchs are usually 0.7 m in height, which can be fine-tuned up or down, and 1.7 m or 1.8 m in width, which can also be customized according to greenhouse dimensions. The length can be customized according to demand, usually between 20 and 30 meters, but to ensure good operation, the length of the rolling bench is preferably not more than 40 meters. Rolling bench mesh is usually made of steel wire welded and hot-dip galvanized to provide excellent corrosion resistance and load-bearing capacity. The mesh size is usually 30mm x 130mm, but customized designs are available upon request.
A significant advantage of ebb and flow rolling benchs is their ability to effectively increase the growing area of a greenhouse. Its layout is flexible and can be arranged vertically or horizontally in islands. Either way,all that is required is a shared “moving walkway”, which can increase the usable space of the greenhouse to more than 80%.
Ebb and flow rolling bench systems are widely used in horticulture, floriculture, nursery management and plant breeding, and have become an indispensable part of modern agricultural production, especially for greenhouse flower growing, vegetable seedling production and rice seedling production.It can use many different types of growing media, such as expanded clay pellets, perlite, peat moss and rockwool. However, the disadvantage of the ebb and flow system is that it can lead to high relative humidity in the plant canopy.
