DIY Ebb and Flow System - The Best And Ultimate Tips 2022 Hydroponics

Today let’s talk about how to DIY ebb and flow system. If you’ve never heard of or witnessed Ebb and Flow hydroponics in the field do not be concerned. The Ebb and Flow hydroponic systems aren’t very often observed on the scene of weed growth. Why? The answer lies in the name.

The entire process of hydroponics relies on the flooding and drainage of roots of plants at specific intervals of time. Floods can be devastating and are definitely not something you would want to occur if you’re growing inside.

Another reason, very closely linked to the one mentioned above is the fact that cannabis is typically grown in illegal ways, which means it is grown in the hydroponic system inside the home.

Being in the middle of a flood in your hands when you’re the illegal grower isn’t something you’d want to do in the last week of week 8, 9, or 10 of your growth… It’s not like we’ve ever had weed grown illegally.

As mentioned previously, Ebb and Flow is a method for growing hydroponics that employs clay pellets, gravel, or lava rock as a cultivation medium.

The systems regularly flood as well as drain plants using nutrient-rich water.

The frequent flood cycles and drainage appear to the plant that is “drowning” in a way that’s the reason:

If the plants are submerged the rounds last between five to fifteen minutes. This implies the plants are made to undergo a process of having their roots submerged by water, just like the Deep Water Culture setup.

However, since these intervals of flooding take only a few minutes and the water drains and the roots aren’t immersed for the length of the plant and this is the major distinction as compared to Deep Water Culture.

What happens to oxygen? And how do plants receive the right amount of oxygen needed to develop properly?

You may be acquainted with the air stone and its function in oxygenating root systems in Deep Water setups, but considering that the Ebb and Flow technique relies on the water of one tank flooding plants that are housed in a different container meaning that the water flowing around will not be adequately oxygenated.

The floods basically “drown” plants, making them crave oxygen. This is when the draining phases come out. In those times when the roots aren’t being flooded, they are absorbing huge quantities of oxygen until the next time of flooding.

The addition of an airstone to the tank will increase oxygen levels of water as well as reduce the possibility of pathogens or other diseases present within the water.

How Do The Ebb And Flow Hydroponic System Work

How Do The System Work

So, how hydroponic system work? The individual potted plants are placed on a drain table, or “growing bed” that can be able to hold several inches of water. The nutrition solution is pumped into and then pumped into the bed.

The plants are supplied with water from the bottom of the drain holes of the pots.

After a couple of minutes of soak, the water pump is cut off and the table is drained in the form of a nutrient solution that flows back to the reservoir beneath it. The flood-drain process repeats itself 2-4 times daily. Simple, but extremely efficient.

In the realm of homemade aquaponic systems (which is a larger world than you imagine because nobody is smart enough to talk about illegal weed-growing operations) We distinguish two fundamental flow and ebb systems.

The first kind is so-called “containers with series” which is appropriately named because of being that every plant is given its particular plant container that gets filled simultaneously with the other containers.

The containers are linked together and must be placed on a firm surface at all times because of flooding times. It is crucial to remember that the height of the overflow tube is the one that determines the water level

This means you must always place your containers higher than the water reservoir. You can place them on a bench, table, or something similar which can hold the weight.

Ebb and Flow System

The other type is known as “flood designs for trays” which is based on the idea of all plants being put in one large tray that is regularly flooded. This design is ideal for the purpose of shifting your plants around and this isn’t an activity you’ll often do in the midst of growing the weed.

But, they have been more well-known in the case of small, low-level indoor weed ops due to the fact that they’re simpler to put together.

This, along with our tendency to prefer to do things in a more difficult way, since if something doesn’t smell good then we don’t bother (we prefer to imagine ourselves as being”the US Marine Corps of weed).

In this article, we’ll be discussing how to create the perfect Ebb or Flow cannabis plants both in the series and flood tray designs. Without further delay this is it.

Considerations to Make Before Getting Started

Before Getting Started Ebb And Flow System

Whatever way you decide to make the move to the next step, there are some essential aspects to take into consideration:

Location and Lighting

Where will you construct or set up your system? Is there enough space to accommodate it? Does the area be suitable for the kind of plants you’d like to cultivate?

And, most importantly, do you put your system inside or outside? If it is indoors, it will require adequate lighting. Outside sunlight will provide illumination.


Size Flow Ebb Greenhouse

How many plants you would like to cultivate? The bigger system, the more quantity of grow sites accessible.

Remember that the bigger your setup is, the bigger everything it needs: water light, nutrients growing medium, and components such as pumping and timing devices. Also, of course, the money needed to cover everything.


The bigger this system’s capacity, the greater the amount of water it needs. Also, you must decide the type of water you’ll utilize (tap water purified water, purified water, or distillation water? ).

Additionally, think about where the water is coming from and the best way to transfer it into your system.

Upkeep and Costs

There are physical maintenance and financial upkeep things to take into consideration. The water has to be changed every two weeks and also requires regular cleaning.

Financially, there are many aspects to take into consideration: water bills, power, nutrients, cleaning solutions the pH as well as the EC testing strips (or pH and EC meters), and more.

How to Make an Ebb and Flow Systems in Just a Few Steps

How to Make an Ebb and Flow Systems in Just a Few Steps

Container in Series

Connect all containers using tubing. Be sure to place it on a flat surface, so that all containers flow evenly throughout flow times.

Connect the overflow tube to your system. The tube is connected to the system in which all containers are linked to one another.

Once the water has reached the level of the overflow point, it flows and then returns to the reservoir, to be returned to the system This means that adjusting the overflow’s height will determine the water’s level during flood times.

Make sure that the water is at the right height in all containers, by adjusting the level of an overflow pipe.

Then connect your equipment to the reservoir, then add nutrients to the water, and then add plants to the reservoirs. Don’t forget to plug in everything that requires plugging, such as your water pumps (plug into the power source and plug in all of its tubings) and an air compressor.

Assembling Flood and Drain Systems

Assembling Flood and Drain Systems

What about a flood and drain system? One of the toughest elements of creating an effective flooding and drainage system involves ensuring that you have the right structure to support your flood tray. Certain growers employ pond liners or build their own beds, however for those who are new to the business user you can use an existing table, or like it is sufficient.

This will allow the flood table to be placed over your nutrition tank. After you’ve got your foundation, you’re able to follow these steps to build the system.

  1. Then, in the flood tray make two 35mm holes into the bottom of the tray. These holes should be about a couple of inches apart. They should also be at one side of the tray since they’ll have to go over the edges of your support.
  2. Attach both fittings to your flood tray. The rubber seal must be located on the inside of your flood tray. The tube fitting’s end is hanging from the underside.
  3. Inject two or three Ebb and Flow extensions into one of the pieces that you have secured onto the tray’s bottom.
  4. Set a screen fixture onto the overflow. Now you’ve constructed an overflow tray. (You might have to modify it in accordance with the pot’s size)
  5. Put one screen on top of the other piece, which is on the base of your flood tray. This is your water intake, which comes from the submersible pump.
  6. Set the flood tray in a position where the fittings are above the reservoir for hydroponics.
  7. You’ll need to measure tubing from the base of your reservoir up to the fixing, which will fix the tube to the flood tray. A thing to keep in mind is that there must be a lid to the tank. You must cut holes big enough for both tubes to go through. Light entering your tank will encourage bacteria to grow.
  8. The tube should be connected to the water pump, then feed into the valve, then join it with the fitting for the inlet.
  9. Attach an additional length of the tube to your overflow so that it fits within the lid, but is clear of the surface of the water. This can aid in the flow of oxygen back into the tank.
  10. The tank should be filled with the appropriate quantity of water and then start the system. Verify that there aren’t any leaks in the inlet or overflow.
  11. Then, you can install your timer, and be ready for your Rockwool pots or cubes that are to be used.

If you are planning to pump air make sure you use black tubing and that the hole inside the lid of your tank is small enough to allow the tube to pass through, but has no illumination.

If you’re in the market for a water source, it is best that you wait till your flood table has been set. If you choose an 8 ft. 4 feet. flood table, a 170 GPH(Gallon per hour) pump will work. If your table’s size is 4 feet. 8 feet. then 300 GPH water pumps will be sufficient.

Flood Tray

Flood Tray greenhouse

Two large, thin trays on a smooth surface. However, make sure that there is enough space between them or beneath them for the reservoir to be able to sit.

Connect all tubing. The reservoir should be placed near (optimally beneath) the flood tray, fill it with water and connect to the air and water pumps.

Create an overflow tube within both flood trays, obviously. This is the reason leaving space beneath the trays (as in the image above) is essential and you’ll have an opening in your flood tray, that will then be filled with an overflow tube (actually two tubes, one for each tray) and when the water flows over the tube, it’ll fall directly back into the reservoir.

Include nutrients in the water and then add plants into the flooding tray.

Connect the water supply and air pump to outlets for power and then take pleasure in.
