Understanding What Hydroponics Is
Hydroponics is an innovative and increasingly popular method of gardening that does not use soil. This technique allows you to grow green, healthy plants in a controlled environment. Before diving into the basics of hydroponics, though, let’s get an understanding of the concept. This section will answer your question: what exactly is hydroponics?
Definition of Hydroponics
Hydroponics, by definition, is a method of growing plants without using traditional soil. Instead, plants are grown in a water-based, nutrient-rich solution. The plant’s roots come into direct contact with the nutrient solution, ensuring that they have constant access to water and essential minerals. This direct contact speeds up the growth process and results in plants that are larger and healthier than those grown in soil.
Brief History of Hydroponics
While hydroponics might seem like a modern concept, it has a long history dating back to ancient civilizations. The hanging gardens of Babylon, one of the seven wonders of the ancient world, used a form of hydroponics. The Aztecs also utilized hydroponics to grow crops on floating rafts on lake surfaces. The scientific understanding and application of hydroponics, however, didn’t occur until the 19th century when researchers began studying the essential requirements for plant growth.
Basics to Hydroponics
If you’re new to hydroponics, understanding the basics is a good starting point. Unlike traditional soil gardening, hydroponics provides plants directly with the nutrients they need to grow. This method often results in faster growth rates and increased yields. A successful hydroponic system involves an optimal balance of light, temperature, pH, nutrients, and water.
Types of Hydroponic Systems
Several types of hydroponic systems exist, each with its own characteristics and benefits. The choices range from deep water culture systems to nutrient film technique systems, aeroponic systems, and wick systems. Choosing a system depends on your needs, space, budget, and level of expertise. While some setups can be very high-tech, there are also simple, cost-effective systems perfect for beginners.
Deciding Which Seedlings to Grow
Now that you understand what hydroponics entails, the next step is deciding which plants you want to grow.
Plants Suited for Hydroponics
While most plants can potentially thrive in hydroponics, some tend to do better than others. Leafy greens like lettuce, spinach, and kale, as well as herbs like basil and mint, make excellent choices for hydroponic gardens. You can also try fruiting plants like tomatoes and peppers.
Factors to Consider When Choosing Seedlings
When deciding on which seedlings to grow, you should consider factors such as the growth rate, space requirements, and maturity time of the plant. You also want to ensure that your chosen plants are suited to your local climate conditions, particularly if your hydroponics system is located outdoors.
Sourcing Quality Seeds
The success of your hydroponic garden begins with the quality of your seeds. It’s crucial to source seeds from reputable suppliers to ensure they are disease-free and of a high standard. Always opt for non-genetically modified seeds and where possible, organic seeds.
Starting Off Seedlings In Hydroponics
After setting up your hydroponic system and choosing your seedlings, the next step is starting off your seedlings in the system.
Preparing the Seeds
Preparing the seeds for hydroponic cultivation is much like preparing them for traditional soil growth. You will need to thoroughly clean the seeds and soak them for a few hours to speed up germination. It’s also advisable to use a seed-starting mix or rockwool to provide a good start for the seeds.
Germinating the Seeds
Seeds need a warm, humid environment to germinate. You can create this environment using a seed tray with a dome lid or a plastic bag. After placing the pre-soaked seeds in the starting mix, keep them under the dome or in the bag until they sprout.
Transplanting Germinated Seeds into the Hydroponic System
Once your seeds have germinated and grown their first set of true leaves, they are ready to be transplanted into your hydroponic system. The complexity of this process will depend on the type of hydroponic system you’re using. Be gentle with the delicate seedlings to avoid damaging the root systems.
Setting Up Your Hydroponic System
Successful hydroponics is reliant on the correct setup of the system. There are several factors to consider, including system selection, component gathering, location scouting, and installation.
Choosing a System
Choosing a particular hydroponic system should be based on your personal needs, resources, and expertise level. The size of your grow area, types of plants you wish to cultivate, and your budget are factors to consider when selecting a system.
Components of a Hydroponic System
Regardless of which hydroponic system you choose, the majority will contain similar basic components like a reservoir (to hold the nutrient solution), a growing medium (where the plants will grow), a pump (to circulate the solution), tubes (for the solution to flow through), and an air stone (for oxygen).
Location for Your System
Choosing the right location for your hydroponic system can significantly impact your plant’s growth. Ideally, your system should be positioned in a location with access to plenty of natural light and a stable temperature. It should also be in a place that is easily accessible for you to regularly check and manage the system.

Once you’ve gathered all your components and chosen a location, you can proceed to set up your system. Follow all the manufacturer’s instructions carefully during installation. Besides the physical setting up of the system, you’ll also need to ensure your reservoir is filled with the appropriate nutrient solution and that the pH level is suitable for your plants.
Nutrient Management for Seedlings
Arguably, one of the most critical aspects of managing seedlings in a hydroponic system is nutrient management.
Understanding Plant Nutrient Requirements
To recreate the nutrient-rich conditions in soil, you’ll need a suitable hydroponic nutrient solution. This nutrient solution must provide all the necessary macro and micro elements required for plant growth such as nitrogen, phosphorus, potassium, calcium, and magnesium.
Choosing the Right Hydroponic Nutrient Solution
There are many pre-made hydroponic nutrients available that are perfect for beginners or if you prefer a hassle-free method. If you want more control, you can create your own nutrient mix. Regardless of which option you take, the nutrient solution must meet your plants’ specific needs.
Feeding Seedlings in Hydroponics
Feeding your seedlings involves adding the nutrient solution to your hydroponic system. The feeding frequency varies depending on the type of hydroponic system and the crop you are growing. Too little nutrients will lead to nutrient deficiencies, while too much can lead to nutrient toxicity.
Managing Water Conditions
Just as nutrients are crucially important in hydroponics, so too is the quality of the water used.
Importance of Water in Hydroponics
Without soil to deliver water, a hydroponic system relies entirely on the water in the nutrient solution to provide hydration to the plants. This is why understanding and managing the water conditions in your hydroponic system is vital.
Maintaining the Correct Water Temperature
Maintaining an optimal water temperature in your hydroponic system is crucial, as water temperature can influence plant growth, nutrient uptake and oxygen levels. Generally, the ideal temperature is between 18-22 degrees centigrade. Outside of this range, plants can become stressed and are more likely to suffer from issues like root rot.
Water Quality Monitoring and Correction
To maintain the quality of water in your hydroponic system, you’ll need to regularly monitor and correct the water’s pH and nutrient concentration levels. You’ll also need to be aware of the water’s overall temperature and ensure that there is sufficient dissolved oxygen for your plants.
Monitoring and Adjusting pH Levels
Just as with traditional soil gardening, pH levels play a crucial role in hydroponics.
Understanding the Role of pH in Hydroponics
pH affects how well plants can absorb nutrients. If the pH is too high or too low, it can prevent the plant roots from taking up certain nutrients, leading to deficiency symptoms. It’s therefore vital to maintain the pH within a range that is optimal for nutrient absorption.
How to Measure pH Levels
To measure the pH of your nutrient solution, you will need a pH testing kit or electronic pH meter. These tools give you a digital or color-coded reading of the pH level.
Adjusting pH in Hydroponic Solutions
If measurements indicate that your pH level is too high or too low, you’ll need to adjust it. To lower the pH, phosphoric acid or sulfuric acid is typically used. To raise the pH, potassium hydroxide or sodium hydroxide can be used. However, adjustments should be made gradually and in small amounts to avoid drastic changes that could stress the plants.
Lighting for Hydroponic Seedlings
The presence of light is fundamental to plant growth. Ensuring your hydroponic seedlings have the right amount and type of light is paramount.
Understanding Plant Light Requirements
Different plants have varying light requirements. While some plants require lots of light to grow, others do fine with less. Plants use the light in the photosynthesis process, where they convert light energy into chemical energy for growth.
Choosing the Right Lighting for Hydroponics
There are several types of grow lights available for hydroponic systems, including fluorescent lights, LED lights, and HID lights. The right lights for your system will depend on several factors, including the type of plants you have, the size of your grow space, and your budget.
