Ebb and Flow Hydroponics Questions Answered

Ebb and flow hydroponics is one of the single most popular ways to grow hydroponically indoors. This system, also called the flood and drain system, is so popular because it is relatively easy to use and maintain but you still get the huge results that you should expect from a hydroponic system. Although it is a very easy system to set up and maintain, there are some common questions about the ebb and flow system that should be answered.

Q. What growing medium is typically used to grow with the ebb and flow system?

A. There really isn’t a right answer to this question. People have chosen to use many different growing mediums however the most popular mediums tend to be rockwool cubes and hydroton. Rockwool cubes hold water much longer than hydroton, so you may want to adjust your watering cycles accordingly.

Q. What type of growing method is best for ebb and flow hydroponics?

A. The most efficient way of growing with an ebb and flow hydroponic system is by implementing the “sea of green” method. This method is comprised of growing a higher number of smaller plants, creating a literal sea of green.

Q. How much should I flood the table with nutrient solution?

A. It is best to flood the table to half to thee quarters the height of the container to ensure even nutrient solution distribution. This will vary with your growing medium.

Q. How much nutrient solution should I have in my reservoir?

A. It is a good idea to have at least 25 percent extra nutrient solution left over after flooding your table. This will allow for daily evaporation. Refill the reservoir daily if needed.

These are some of the most popular questions about ebb and flow hydroponics. This system is relatively easy to use, however; you want to make sure you follow these small guidelines in order to have the highest chance of having a successful harvest.

What is Hydroponics?

Hydroponics is the science of growing plants without soil, most often in a soilless mix. When using hydroponics such as an ebb and flow hydroponics system, the nutrient uptake and grow medium oxygen content can be controlled easily. Being able to manage both of these aspects of growth gives the grower bigger yields in a shorter amount of time.

They inert hydroponic medium contains essentially no nutrients. This means that all nutrients are supplied through a nutrient solution fed to the plant. This nutrient solution is fed to the plant many times through a flooding system (as with the ebb and flow system). The solution then drains away and leaves fresh oxygen trapped in the soilless medium around the roots which speeds nutrient uptake by the tiny root hairs. The reason hydroponic gardening works so well is because the plants are able to intake the highest level of plant food/nutrients as possible. Soil on the other hand lacks rich oxygen content which in turn limits the amount of food the plant can intake.

Some people think that hydroponic gardens often require less maintenance and care than a soil system. This can be true depending on your setup, but chances are you will need to spend a bit more time in the garden to help maintain your hydroponic system. The duties will be a little different. You won’t spend as much time directly watering the plants as in soil, but you will have extra time devoted to checking ppm and ph levels, adjusting tubing, filling the reservoir and just generally maintaining your system. Also, when your plants grow faster, there will be more work to do to the plants and your environment to accommodate this rapid growth.

Because of this more productive growth, plants will produce a bit less foliage and more dense flower buds. Plants are even ready for harvest a few days before soil gardens due to the faster growth. Although the results are great using a hydroponics system, it is also important to remember that hydroponic systems, including ebb and flow hydroponics, are not as forgiving as soil gardens. If you have a pump fail or other such problems, you could lose a whole crop in a very short period of time. Just as long as you have the patience and knowledge, you will see great results from hydroponic gardening.

Why Hydroponics Systems?

First off, let me give you a definition of hydroponics: Hydroponics is the science of growing plants without soil, most often in a soil-less mix.

That is a pretty general explanation of what hydroponics is, but that does truly cover the basis for what makes it hydroponics. When growing in soil as humans have for years and years, the plants are actually getting a portion of their nutrients from the soil itself. The difference with hydroponics is that the plant is not getting any nutrients from the growing medium, but instead the nutrients are fed to the plant through a nutrient solution that is fed into the hydroponic medium. By growing using hydroponics, this then gives the grower the ability to control the nutrient intake and oxygen intake of the plants.

Hydroponics works so well because the plant is able to take in food as fast as it can be used. It is also able to get a high amount of oxygen, especially compared to soil growing where oxygen to the roots is limited.

If you are interested in using hydroponics to make your gardening job easier, think again. Contrary to popular belief, hydroponic gardening, such as Ebb and Flow Hydroponics, does usually take a little bit more maintenance and time. You will need to spend more time in the garden because your plants will grow faster, there are more things to check, and more can go wrong.

Don’t think hydro isn’t worth it though, people all over the world wouldn’t be using these hydroponic systems if they weren’t worth it! Plants will grow less leafy foliage and more dense flower buds, and plants are actually ready for harvest a few days earlier than growing in soil.

Besides ebb and flow hydroponics systems, there are also the following systems: air tables, deep water culture (dwc), top feed systems, nutrient film technique (nft), and aeroponics.

Why Ebb and Flow?

Ebb and Flow Hydroponics, often called "flood and drain", are popular because of their proven track record of being low maintenance, easy to use gardens. Ebb and flow systems are set up using a large reservoir or tub where the plants are placed in either pots or rockwool cubes. The reservoir or table will usually hold up to 4 inches of nutrient solution which is usually pumped up to the table from a reservoir sitting below the table. This nutrient solution floods the bottom of the tray, pushing old used up oxygen out of the plant root system and replacing it with the nutrient rich solution.

This solution sits in the tray for a specified period of time, depending on your system, allowing the plants to get plenty of nutrients. The solution is then drained completely out from the tray which sucks new fresh oxygen into the root system, allowing for maximum plant growth. The used nutrient solution is usually diverted back to the reservoir from which it came and can be reused until it is gone. This ebb and flow system is perfect for growing smaller plants using a "sea of green" growing technique.

Ebb and flow hydroponic systems can be used with an organic nutrient solution or the traditional chemical fertilizers, but it is completely up to the grower and suits both just fine. Many growers love this system due to the low maintenance aspect of it, but at the same time the results that are produced from this system. The ebb and flow system is number one for these reasons!
