The General Hydroponics version of the ebb and flow table

The Ebb & Flow system uses sub-irrigation; the nutrient solution floods the substrate and then runs off into the tank when the pump stops. This regular ebb and flow of the solution provides the root system with excellent oxygenation.

This type of system is designed for beginners who are looking for a technically simple system that is easy to use, and for experienced growers who are looking for a modular system that can adapt to the specifics of their growing environment that truly maximises the yield.

It is the very definition of the versatile growing system: it allows the use of a wide variety of containers (size, material, shape) and substrates or substrate mixes (clay beads, coir, perlite, soil).

To complete the list of this system’s advantages:

  • It has no risks of leakage or overflow all with minimum maintenance.
  • Its autonomy allows you to leave it unattended for a few days without any risk to your plants.
  • It is easy to clean.


  • EBB&GROW® is manufactured in France in our workshops from 100% recycled* plastic using a process that gives it unrivalled strength. We are the only company on the market to offer a LIFETIME GUARANTEE** for moulded plastics (Tank and growing table). This does not add anything to the price.
  • Its compact design makes it possible to hold up to 32 15×15 cm plastic pots or 22 fabric 1 Gallon pots (3.75L) without any space loss.
  • It withstands the weight: the tank supports the centre of the growing table. This is why the upper tray does not warp.
  • Low system: As the system is only 38 cm high, it leaves your plants enough space to grow.
  • High capacity tank: Up to 100L of solution.
  • Very low electricity consumption: 6.5 Watts


Pots (not included):

Several solutions are available:

  • Plastic pots: a cheap solution
  • Fabric pots: more expensive, but they have the advantage of allowing the nutrient solution to penetrate their full surface area and limit the dispersion of substrate in the system.


You have the choice here too. Using the EBB&GROW® you can grow:

  • Using clay beads (Grorox)
  • Using coir or a coir/perlite mix
  • Using soil
  • Using rockwool (we do not recommend this as it is non recyclable)

Tip: You can also dispense with pots altogether and just fill the top tray with a Grorox and CocoTek Pure mix (60%/40%). This is one of the methods we use in our greenhouse.


An ebb and flow table requires to use a timer (not included) that regulates the irrigation cycles. For irrigation cycles of less than 15 minutes, you should choose a digital timer that supports minute by minute programming.

The pump on/off cycles are to be adapted depending on how you work and:

  • The substrate quantity and type
  • Your climate
  • How much your plants consume
