Growing Hydroponic Coffee – Everything You Need To Know

Most probably, you are here because of two reasons: Either you are wondering if it is possible to grow coffee hydroponically or you already know that it is possible and trying to find out how.

Keep reading because, in this article, we will provide you with the answers you’re looking for.

You will find out how to grow hydroponic coffee properly, what are the suitable conditions, and how to avoid common mistakes.

Common Issues in Growing Hydroponic Coffee
Here is how your plant will look approximately three months in the growth process

 

Growing a hydroponic coffee can be rewarding and challenging at the same time.

These are some things, however, to consider before starting a coffee production. You have to pay attention to the type of coffee, the environmental conditions, and the nutrients that are required.

Here is a briefing of your hydroponic coffee growth.

If you have decided that you will give it a shot, first of all, make sure to remove the tiny plant from the soil and wash its roots with warm water.

Next, place the plant in a growing container. Some people usually skip this phase and directly put the plant in a net cup. You can fill the container or cup, with decorative rocks and clay pebbles, if you feel like it.

In the next few weeks, you will notice a significant growth in the plant. The container has to be filled with water. If you are using passive hydroponics, you won’t need a water pump.

Otherwise, you will have to install one, and THIS ARTICLE will help you determine the size you need and where to find.

It is perfect for decoration of the house. With the hydroponic system, you don’t need to feed it and pay no attention in general.

It will just happily grow and shine beautiful, asking for nothing in return.

The plant should be exposed to natural sunlight, but if you have no access or you are not able to do that, later in the article, we will discuss all the artificial lighting you can provide your plant with.

It may take up to 9 months before you will have to add any sort of nutrient solution. But once the time comes whenever you start to notice significant growth, it is extremely important in order to maintain its healthy life.

Can you imagine any other type of system that can keep houseplants happy and healthy for more than 250 days without maintenance? It is spectacular!

However, you may start to cut off half of the root system after that time, and there are going to be no adverse effects on the plant. You might need to do that only if you notice any of the roots brownings.

For reference, here is how the plant will look after a year of healthy growth.

 

Now we will start with the most critical factor, which is essential for coffee proper growth. We will include the hydroponic growth requirements as well as for regular growth.

What are The Required Nutrients?

It is essential to provide the plants with the ideal soil and nutrients conditions for their optimal growth. The soil needs to be well-drained and loamy.

When the plants are young, you should know that they require exceptional quantities of phosphorous. After the second year of growth, the amounts are getting balanced and easier to maintain alive.

Once the plants are developed and strong, each year’s application of 1400 pounds should be added. Mixing of magnesium, iron, and nutrients containing zinc is required to be continuously added.

Experienced growers can develop hydroponic growth, but ordinary growth can be handled successfully even by beginners.

Suitable Environmental Conditions

There are strict environmental conditions in which coffee growth is optimal. They are not necessary for hydroponic growth, but following them will provide you with the best results. These environmental conditions are referring to the people that are aiming for production more than decoration.

The production will be very low or even not producing at all if the environmental conditions are not met.

The temperatures have to be from 60 to 70 degrees Fahrenheit, and the high humidity is mandatory. If there is a possibility for a cloud-like or misty environment for growth is a huge plus, but not that essential.

For the ingrow growing, it is crucial to provide the plants with the right lighting, which we will discuss later in the article, so keep reading.

A proper touch on the airflow is essential also and highly recommended to provide the plants with dry, and reality cool growing space. At the time of harvesting, drier conditions are recommended to simplify the process.

Soil Requirements

The coffee crop can be grown on a variety of different soil types. However, one of the recommended soils is sandy loam, or the “shadow soil” is the ideal solution as it is reached on organic matter.

The water balance is a factor that has been taken under consideration because it may play a vital role in the coffee growing in general.

It is recommended that the soil deficiencies to be supplemented with the required nutrients before and after planting the coffee until the perfect balance is achieved.

Common Issues in Growing Hydroponic Coffee

If you have been reading from the beginning, you should be aware of the suitable conditions that are required for the proper growth of hydroponic coffee. However, most of the mistakes are related exactly to the conditions.

Mediterranean climate is not suitable for the coffee plant in general, and if you are located in such an area, you should consider indoor growing. Growth issues can occur if the recommended lightning, moisture, and temperature level conditions are not met.

There is not a variety of people that are growing coffee hydroponically, but the few that have attempted it are mainly struggling when the plant reaches 2 meters high.

Of course, this can occur late in the growing process. Still, eventually, the plant has to be removed from the hydroponic system and placed in a greenhouse or suitable environment accordingly for its height.

Otherwise, the plant will fall because of its weight.

The wind, on the other hand, can cause problems even before the plant reaches 2 meters. If your system is exposed to faster airflow than the recommended breeze, it can cause the plant to break and die.

How To Build a Hydroponic System for Coffee Growing

Even if you are a beginner, don’t get discouraged and get started! You don’t need years of experience to do it rightfully.

You can easily get the advantages of this method by following the steps we have prepared for you.

Container Preparations

Empty the container and make a hole, with a diameter about an inch, for around 6 centimeters from the bottom.

Then you need a PVC elbow joint or a similar object that can feed it through the outside of the hole. (Do not forget that it has to face down).

Attach another PVC elbow, but this time on the other end, inside the container facing down as well.

Fill the container about little more than the half, and insert the plant that you want to grow, making sure that the roots are healthy and in the water.

Keep in mind that any container made of plastic will get the job done, so do not waste your time on finding the perfect one.

The roof of your container has to have a hole big enough for the body of the plant to go around and the leaves to be left outside.

Irrigation System Preparation

The fastest and easiest way to create your irrigation system is to use a half an inch main line attached to your water pump. Attach the main to your outflow source of the container and place it in a suitable and secure place.

At the end of the mainline, you can stick a screwdriver or ¼ inch poly nail that has barbed coupling on the one end. After the feeder line is attached, you can stick the other end into the growing medium.

The next step should be to bore holes into the drainpipe that is aligning with the elbow joint you have made earlier on the container. Attach another PVC pipe to the bottom of the elbow and put it through the hole into the drain pipe.

Everything that you have to do now is check for leaks. It is highly possible for a system made of everyday items to have leaked, so do not worry, just seal them and you are ready to go.

Conclusion

You now have a basic understanding of the hydrophobic coffee growth as you read about all the necessary precautions you need to take, conditions, feeding, and finally, how to build a hydroponic system for the coffee plants at home.

You will need to do some research to learn how to grow different crops hydroponically, but in general, there is not that much to learn.

We wish you a successful growth!
