you need a tray... a res... a pump... fittings & hose...

and it works like this...





here is a DIY version from the GrowFAQ

How do I make an ebb & flow

How do I make an ebb & flow
hydroponic system?





The goal: To demonstrate the construction of an Ebb & Flow hydroponic system.

The system being constructed is small, however the design is the same as larger systems.





Parts list...

  • Restaurant bus tub, 15 1/2" x 20 1/2" x 4 1/2", flood tray.
  • Restaurant bus tub, 15 1/2" x 20 1/2" x 7", reservoir.
  • Reservoir lid, 15 3/4" x 22".
  • Overflow fitting.
  • Fill/drain fitting.
  • Water pump, 70 gph.
  • Tubing, 1/2" ID.
  • Aquarium air pump.
  • Air stones.
  • Green air line.

    Notice, in the pictures above, the one inch holes, in the flood tray for the overflow, and fill/drain fittings, also, the two inch holes in the lid, for the fittings to pass through.


    A view of the plumbed flood tray with lid. See how it fits over the fittings.​


    This is a view of the reservoir with lid, and plumbed flood tray.


    Here, it's all assembled. The water and air pumps are not shown. The power cord, and air lines fit between, the reservoir and lid. A small notch may need to be added, to avoid pinching the air lines, and to help the flood tray sit level.


    Assembled with six 5 1/2" square pots. Notice the easy access to both fittings. The fill/drain fitting has a connector for a 1/2" hose, under the screen. Remove the screen, connect the hose, turn the pump on, and pump out the nutrient solution. Makes reservoir change outs very easy.


    Another view of the system.


    Note: Choosing a container...

    Not all containers are made equal. Some are very sturdy, while others are not. Using a weak container will only lead to failure and a flood. Choose heavy duty containers. Also, some containers will need a center support to keep them level under the weight of the nutrient solution.

    Note: About sizes...

    The reservoir should be large enough, to hold two, to three times the volume of the flood tray or table. The pump should be sized to flood the tray in 5 min. or less.

Good video...

But I do not like that uses the word NETPOTS... netpots have no business in ebb/flow...

DWC AERO NFT sure... but not in a true ebb flow... I can go into it if you want...:lol:

and I do not like the fact that he says to drill holes in the bottom of the tray without clarification...

The solution is supposed to return to the res via the fill tube... which should be the lowest spot on the tray...

But since rubbermaid totes are different... and have weird low spots... you need to drill the holes he mentions...

But that is part of not using the right materials..

not part of a true ebb flow system...;-)

But everything else is spot on ... and in a real nice presentation too...:clap:

I like it...:clap::clap::clap:

shall we take another look?:razz:

i use mesh bottom pots in my setup thats what the guys at worms way told me to do

One of the great conveniences of doing ebb flow in pots is that the plants are mobile...

Using netpots will cause the roots to tangle and or get airpruned...

I know quite a few users here that started using netpots... but after they switched to solid pots, they realized how much more convenient it is to be able to move the plants around...

Just my thought though... and a lot of other Ebb/Flowers as well...
