High-tech type of hydroponic gardening.
Growing medium is primarily air.
The roots hang in the air and are misted with nutrient solution.
Needs a short cycle timer that runs the pump for a few seconds every couple of minutes.
Drip system of Hydroponics
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.
