The nutrient liquids are pumped through tubing from a reservoir in these systems - then dripped through the growing medium (usually Rockwool) from above down a feed pipe.The flow rate is reduced by a dripper to each individual plant.The excess nutrient may then be re-circulated from the nutrient tank. If the nutrient is allowed to drain away it is known as known as 'run to waste'.
