Flood and Drain Systems
Flood and Drain is a very popular, versatile and effective hydroponic technique. In Flood and Drain or 'ebb and flood' as it sometimes known plants sit either on planter tables or in pots / buckets placed above or alongside a nutrient tank or reservoir. Plants are potted in clay pebbles and periodically a water pump is engaged by a timer that floods the pebbles providing your root zone with water and nutrients, once the pump disengages the water drains away back to the reservoir.
