The multiflow system is the only flood and drain system which allows the grower to move individual plants around regardless of which stage you are in the plants life. Another advantage is you can add to your existing system for less cost.

If you only wish to flood and drain one to four plants the EF 120 is probably the best choice for you the tank holds more than 50L and is so simple to set up it can be completely assembled in less than five mins only needs about 30 liters of pebbles.

The E.F. 230 is probably the most popular flood and drain table as it is 44" x44" so it sits nice under a 600w light it is just as easy to set up as the 120 and requires about 80L of pebbles and is normally used to house between 10 and 20 plants. This system sits on top of its tank which holds 123L of water.

The 420 is a long and narrow table ideal for attic spaces fits around the same number of plants as the EF 230 and requires about the same amount of pebbles, seems to be popular for growers who want to grow in a narrow space. As with all the EF range it sits on its own tank, this one holds around 100L.

There is a 2m x 1m EF 620 but most people prefer to use two EF 230s just for ease as the cost is around the same.
