Ebb and Flow Bench – Labor, Water and Fertilizer Saving Nursery

Ebb and flow benches, also known as ebb and flow tables, flood and drain tables, or flood benches, are an increasingly popular greenhouse bench for propagating seedlings and hydroponic growing in modern times.

It is specially equipped with an ebb and flow system made of ABS bench trays that are molded with a network of drainage channels. This unique structure allows nutrient-rich water pumped from the reservoir watering all plants evenly throughout the entire surface of the greenhouse bench and then draining completely when the watering is finished. The water then returns to the reservoir under gravity for recycling.

Ebb and flow benches help you save both labor and nutrient-rich water while ensuring seedlings grow strong and vigorous.

Mobile ebb & flow bench with extended frame

Features

The fully recirculating system saves 50%–90% water, 75%–90% fertilizer and 60%–90% labor costs when compared to traditional watering methods.
Plants are always watered very evenly while keeping the floor remaining clean and dry.
Extended frame type is available for installing lighting system.
It can easily control relative humidity, lighting and carbon dioxide level in the growing environment.
Most plants grown on ebb & flow benches tend to finish 1 to 2 weeks earlier than other irrigation systems.
Ebb & flow benches can be stacked in propagation and seeding areas, and growth chambers.
Compatible with many computer control systems and various specifications are available to meet different demands.
