Hydroponics For Indoors Cultivation

Basic Principles of Hydroponics

Before diving into the different types of small-scale hydroponics systems, it’s essential to understand the basic principles behind hydroponic cultivation. Unlike traditional soil-based gardening, where plants extract nutrients from the soil, hydroponics delivers nutrients directly to the plants’ root systems through water solutions. By eliminating the need for soil, hydroponics provides a controlled environment where plants can focus on growth rather than searching for nutrients. This results in faster growth rates, higher yields, and the ability to grow plants in limited spaces.

Types of Small-Scale Hydroponics Systems

Nutrient Film Technique (NFT)

The Nutrient Film Technique (NFT) is a popular hydroponic system for indoor cultivation. In an NFT system, a shallow stream of nutrient-rich water flows over the roots of the plants, providing them with essential nutrients. The excess water then returns to the reservoir, creating a continuous cycle. NFT systems are known for their simplicity, efficiency, and suitability for growing leafy greens and herbs. However, they require careful monitoring to prevent drying out of the nutrient film.

Deep Water Culture (DWC)

Deep Water Culture (DWC) is another effective hydroponic system for indoor gardening. In DWC systems, plants’ roots are suspended in a nutrient-rich solution, allowing for direct oxygenation and nutrient uptake. Air stones or diffusers provide oxygen to the roots, promoting healthy growth. DWC systems are relatively easy to set up and are ideal for beginners. However, they can be challenging to maintain in larger setups due to the need for proper oxygenation.

Drip System

The drip system is a versatile hydroponic system commonly used for indoor cultivation. In this system, nutrient solutions are delivered to the plants through a network of tubes and emitters, which drip the solution directly onto the growing medium or the plant’s root system. Drip systems allow for precise control over nutrient delivery and are suitable for a wide range of plants. However, they require regular maintenance to prevent clogging of emitters.


Aeroponics is an advanced hydroponic system that utilizes a misting mechanism to deliver nutrient solutions directly to the plant’s roots. The roots are suspended in air, and a fine mist of nutrient solution is periodically sprayed onto them. This method provides maximum oxygenation to the roots, promoting rapid growth and nutrient absorption. Aeroponics systems are highly efficient but require careful monitoring and maintenance to prevent drying out of the roots.

Choosing the Right System for Indoor Cultivation

When selecting a small-scale hydroponics system for indoor cultivation, several factors should be considered. Firstly, the available space should align with the chosen system. NFT and DWC systems are suitable for smaller spaces, while drip systems and aeroponics may require more room. Additionally, the type of plants you intend to grow plays a crucial role in system selection. Leafy greens, herbs, and smaller vegetables thrive in NFT and DWC systems, whereas larger plants may require drip systems or aeroponics. Finally, your level of experience and willingness to invest time in maintenance should also be considered when choosing a system.

Recommended Plants for Small Scale Hydroponics

When it comes to selecting plants for small-scale hydroponics, several options thrive in indoor environments. Leafy green vegetables such as lettuce, spinach, and kale are ideal choices due to their rapid growth and shallow root systems. Herbs like basil, parsley, and mint also flourish in hydroponic setups, providing fresh flavors for culinary enthusiasts. Other suitable options include cherry tomatoes, cucumbers, and fruits such as strawberries, which can be trellised for efficient use of vertical space. Consider the growth requirements of each plant, including lighting, temperature, and pH levels, when making your selection.
