General Hydroponics Ebb & Grow Tray

The grow tray, or Ebb & Flow, works by sub-irrigation: The nutrient solution irrigates the substrate and drains back into the reservoir when the pump stops. This regular ebb and flow of the solution allows for excellent oxygenation of the root system. This type of system is aimed at both beginners looking for a simple, easy-to-use tool, and experienced growers who want a modular system that adapts to the specificities of their growing environment and truly maximizes yield. It is the quintessential versatile growing system: It allows for a wide variety of containers (size, material, shape) and, above all, substrates or substrate mixtures (clay pebbles, coconut fiber, perlite, soil). There is no possibility of leaks or overflows, even with minimal maintenance. Its autonomy allows you to be away for a few days without posing a risk to the plants. Easy to clean.
