Pots are 11ltr the brain holds 20ltr and the tank holds 200ltr The Multi flow System is basically an ebb & flow type hydroponic system that uses gravity as its major source of moving water through the system.

Also, because this system is an ebb & flow system, as the water is drained out it actually pulls oxygen down to the roots.

Combine the best in both worlds, the flexibility of pots and the growth of hydroponics.

Using the Multiflow is very simple.  First of all you must layout all of the pots and set them up on a level surface.  Then connect the pots together using various fittings and tubing (included).  Once you have done this plug the power cord of the pump  which is in the reservoir into the controller unit and set your watering times.  When the timer reaches the watering time you have selected, the pump turns on inside the reservoir pumping nutrient solution into the controller unit.  This will continue pumping into the controller while gravity pushes the water out to the other pots.  Once the desired watering level is reached, the float switches then cut the power to the pump in the reservoir.

 As long as the timer is on the system will maintain this watering level.  Once the timer turns off, the pump inside the controller is engaged and the nutrient solution is then pumped back into the reservoir.  This will continue until the water level reaches the preset drain depth then the pump will be turned off.   Since the pumps are only pumping a short distance, to and from the reservoir, wear and tear is greatly reduced and will ensure that your pumps last for a long time.

Clay pebbles are an excellent medium for pot culture and Flood and Drain systems. When planting into clay pebbles, the plants should be inserted well into the depth of the substrate to encourage rapid root growth. Plants placed onto the surface of the substrate will not easily root into the top layer.
