ECO Farm is the most efficient ebb & flow system on the market. With the easy-to-program controller unit, you can pretty much "set it and forget it." And since your pumps are only pumping a short time each day, the system is extremely reliable and efficient. Just set the fill and drain cycles, and the controller unit does the rest!
As for safety, the Grow Flow is the only unit available with fail-safe overflow protection. If the float valve stops operating, the LED indicator lights up on the control panel and the emergency shut-off valve automatically shuts down the system, preventing any spillage or damage to your growing area.
Ebb and Flow or “flood and drain” is an effective, relatively low-cost, and very versatile hydroponic system, which makes it great for beginners and pros alike. Systems come in several shapes and sizes and can be used for the early stages of vegetative growth all the way through harvest.
The mechanics are simple: A hydroponic ebb and flow system works by periodically pumping nutrient-rich solution to the plant sites once, or more often, several times a day. This flooding (the ‘flow’) meets the nutritional needs of your plants by saturating the grow medium with solution. After the mediums have been saturated, the pumps are stopped, and the ‘ebb’ process begins. The ebb is the draining of the solution back to the reservoir. This period in between the flood cycles creates a well aerated and moist environment where your roots, and thus your plants, will thrive.
The ebb and flow system cycles are accomplished with just a few simple hydro components including a central reservoir, a flood tray or modules (buckets), submersible pump(s), timer(s), and sometimes float valves or overflow drains. In most systems, float valves or overflow drains prevent overfilling, while one or two timers control the intervals at which your nutrient reservoirs flood and drain the solution (typically multiple times throughout the day). This straightforward setup with a minimal number of components not only simplifies feeding but also creates a highly effective method of nutrient delivery and root aeration.
