Building your own hydroponic garden is easier than you might think and can bring numerous benefits, such as having fresh, nutritious food all year round, saving money, reducing environmental impact and even serving as a relaxing hobby. In this complete guide, we’ll show you everything you need to know to start your hydroponics journey, from choosing materials to caring for the plants.
What is hydroponics?
Hydroponics is a cultivation technique that does not require the use of soil. The plants grow in an inert medium, such as expanded clay or rock wool, and their roots are bathed in a nutrient solution rich in water and essential nutrients for their development.
Why choose hydroponics?
- Faster growth: Hydroponic plants tend to grow faster because the nutrients are always available to the roots.
- Greater productivity: You can obtain a greater quantity of food in a smaller space.
- Less water consumption: Hydroponics uses water more efficiently because it is reused in a closed system.
- Higher quality: Hydroponic food is generally more nutritious and tastier.
- Grow anywhere: You can grow your food at home, in your apartment, on your balcony or even in an office.
- Sustainability: Hydroponics reduces the use of pesticides and chemical fertilizers, contributing to a healthier environment.
Hydroponics vs. Traditional Agriculture
Unlike traditional agriculture, which relies on the soil to supply plants with nutrients, hydroponics offers much greater control over the growing process. This means that you can adjust the amount of nutrients, temperature and lighting to optimize the growth of your plants. What’s more, hydroponics allows you to grow plants in controlled environments, such as indoors, which is ideal for regions with adverse climates.
Setting up your hydroponic garden: What materials do you need?
Are you excited about the idea of having your own hydroponic garden at home? Now that you know what hydroponics is and what its benefits are, we’ll show you the basic materials you need to set up your system.

Which Hydroponic System to Choose?
Now that you know what materials you need to set up your hydroponic garden, it’s time to choose the type of system that’s right for you. There are several hydroponic systems available, each with its own characteristics and advantages.
But which system should you choose?
Choosing the ideal system depends on several factors, such as the space available, your level of experience and the type of plant you want to grow. Let’s take a look at some of the most popular hydroponic systems and their main characteristics:
Types of Hydroponic Systems
- Deep Water Culture (DWC): In this system, the roots of the plants are submerged in a reservoir with a nutrient solution. It is one of the simplest and easiest systems to set up, but can be more susceptible to algae growth.
- Nutrient Film Technique (NFT): In this system, a thin film of nutrient solution flows continuously over the roots of the plants, which are suspended in inclined channels. It is an efficient system and allows good control over the temperature of the nutrient solution.
- Wick System: In this system, the roots of the plants are in contact with a wick that is immersed in the nutrient solution. It’s a very simple system and ideal for beginners, but can be limited in terms of plant growth.
- Aeroponics: In this system, the roots of the plants are suspended in the air and sprayed with a fine mist of nutrient solution. It is an advanced system and requires precise control of humidity and temperature.
- Ebb and Flow: In this system, the tray in which the plants are planted is periodically filled and emptied with the nutrient solution. It’s a versatile system and easy to control.
Which system to choose?
- Available space: If you have little space, vertical systems or systems that use smaller containers are more suitable.
- Level of experience: If you are a beginner, DWC or Wick systems may be a good option, as they are simpler to set up and operate.
- Type of plant: Some plants adapt better to certain systems. For example, plants with more delicate roots, such as lettuce, can benefit from systems such as NFT.
Other factors to consider:
- Cost: The cost of materials can vary greatly between different systems.
- Maintenance: Some systems require more maintenance than others.
- Productivity: The productivity of each system can vary depending on various factors, such as the variety of plant and the growing conditions.
There is no perfect hydroponic system. Choosing the ideal system depends on your needs and preferences. The most important thing is to choose a system that you feel comfortable setting up and looking after.
