Ebb and Flow Gardens
Simple and reliable, these gardens periodically flood a tray which contains a hydroponic medium. The medium, such hydrocorrel, can be loose or in containers.
This is a higher performance garden than Ebb and Flow since the feeding is continuous. An air pump percolates nutrient up a column and through a drip ring. Highly oxygenated nutrient flows down through the growing medium and back into the reservoir.
This is the Highest performance garden of the three. The roots are suspended in the air and misted with the nutrient solution. This results in very high levels of oxygenation
