Most widely used type of hydroponic system in the world. A timer controls a submersed pump.
The timer turns the pump on and nutrient solution is dripped onto thebase of each plant by a small drip line.
Recovery Drip System: excess nutrient solution that runs off iscollected back in the reservoir for re-use.
The Non-Recovery System does not collect the run off.
A recovery system:· uses nutrient solution a bit more efficiently and allows for the use of a more inexpensive timer.
The non-recovery system:· needs to have a more precise time· Watering cycles can be adjusted to insure that the plantsget enough nutrient solution and the runoff is kept to a minimum. Requires less maintenance.
