Flood and Drain (aka Ebb and Flow) is a very effective, low-cost, and versatile hydroponic system. The mechanics are straightforward; nutrients are pumped up into a tray flooding the plant sites several times a day, working off a timer. The medium is saturated, and then the system is drained. This period between flood cycles creates a well-aerated and moist environment where your roots, and thus your plants, will thrive!
