(e) What is Ebb and Flow Hydroponic System?

The ebb and flow or flood and drain method works by flooding the grow area with nutrient solution at specific intervals, which then drain back into a reservoir containing a pump on a timer. This type of flood and drain hydroponics system is ideal for plants that are used to alternating periods of dryness to wet.

(f) How to Setup Ebb and Flow Hydroponic System?

Okay, let's get started with some planning:

First you need to work out what kind of space you will have available for you plants so you can scale your system accordingly.

It's also important to remember that your plants can grow HUGE meaning high water and nutrient requirements! A smaller reservoir will mean that you need to add water more often.

No matter how small or big a system you build, the principle is exactly the same as shown on this building example.

The growing container (the upper part) can be any shape you wish. For practical reasons, sizes like 60 x 60cm or 80x80cm and bigger are a good plan. If in doubt go for squares or near square rectangles. Be sure to leave adequate space around the system. Your chilli plants will thank you for it.

For bigger systems I would recommend a long (but not too wide) system. My "monster" 30 cm x 5 meter flood & drain system has been ideal for efficient and easy growing.

Back to the basic principle: the plant container (upper part) will be filled with expanded clay pebbles. Some growers mix in 50 / 50 diatomite too for added plant-available silica. (If you go this route, be sure to reduce the frequency of your irrigation as diatomite is more absorbent than clay pebbles.)

I usually start my seedlings off by germinating them in rockwool cubes and then transferring into rockwool blocks. Sometimes I plant aeroponic cuttings (without rockwool or any other propagation media) and that works also well. Just be extra careful with those roots when transplanting.

How the System Works

The timer is first set to pump nutrient solution to the upper tray twice a day.

It floods the upper tray and waters the roots and expanded clay balls with nutrient solution. After a minute (or any time suitable for your ebb) the timer will turn off the pump and the nutrient solution drains back to nutrient container back through the pump. (Make sure your pump allows water to drain back through it. Don't worry - those beautiful people at your local grow shop will sort you out.) An overflow drain ensures that any excess water drains back to reservoir before the expanded clay starts to flow. Best practice is to set the timer to stop the pump when the water reaches overflow tube. A digital (rather than segmental) timer affords the grower more accuracy in setting irrigation times. The overflow should be adjustable so as to make the incoming nutrient solution deep enough to reach the roots of the plants.

Errrr … that's it!

So why it is so efficient then?
