Cascading Flood Floors:

The cascading style of flood floor has the water supplied on the high side of the growing area and running a ¼” to 3/8” depth across the floor. The water then runs immediately into the drain piping and is returned to the tank that supplied it.

It takes 30-45 second for the water to cross the floor and enter the drain line. This system allows the grower to water evenly across the crop even if he/she reduces the irrigation cycle to restrict the amount of capillary action if he/ she wants to hold back the crop.

Unlike the traditional style, unfiltered water never enters the supply line. The drain line does not require any valving as it is always open. Since water begins to return almost immediately to the tank system, smaller tanks can be used and there is little to no time between watering floors.

If you intend to grow a smaller (6” and under ) pot ,tray liner, propagation or rockwool cube, this is the system to choose.
