Aquaponics is an innovative way of growing plants and fish together in a sustainable, symbiotic system. Indoor aquaponics is becoming increasingly popular, offering year-round growing and the ability to grow fresh produce in even the smallest of spaces. Lighting is an essential part of the indoor aquaponics setup, providing the necessary light for plants, fish, and bacteria to thrive. In this article, we will discuss the various lighting options available for indoor aquaponics systems.

Understanding Lighting for Indoor Aquaponics Systems

While natural sunlight is the most effective and efficient source of light for an aquaponics system, indoor aquaponics systems require artificial lighting. Lighting is essential for plants to carry out photosynthesis, which produces energy in the form of glucose. Photosynthesis also releases oxygen, which is necessary for fish and bacteria to survive.

Lighting is also important for fish health, as it regulates their metabolism and behavior. For example, fish require a period of darkness to sleep, and prolonged periods of light can lead to stress and disease.

Types of Lights for Indoor Aquaponics Systems

Fluorescent Lighting

Fluorescent lighting is a popular option for indoor aquaponics systems due to its low cost and energy efficiency. Fluorescent lights are available in a variety of spectrum options, including warm white, cool white, and daylight. Daylight spectrum fluorescent lights are the most suitable for plant growth.

LED Lighting

LED lighting is becoming increasingly popular due to its energy efficiency and long lifespan. LEDs are available in a wide range of spectrum options, and their energy-efficient nature means that they emit minimal heat, making them ideal for indoor aquaponics systems.

High-Intensity Discharge (HID) Lighting

HID lighting is a high-intensity lighting option that produces a lot of heat and light. HID lights are available in two types: Metal Halide (MH) and High-Pressure Sodium (HPS). Metal Halide light produces a cool blue light, suitable for vegetative growth, whereas HPS lights produce a warm, red light suitable for flowering and fruiting plants.

Factors to Consider When Choosing Lighting for Indoor Aquaponics Systems

When choosing lighting for indoor aquaponics systems, several factors need consideration.

Light Intensity and Spectrum

Light intensity and spectrum differ between light types and determine the effectiveness of lighting for plant growth. Plants require different light spectrums to grow effectively at different stages of their growth. Vegetative plants require different spectrum in comparison to flowering plants.

Cost and Efficiency

Cost and efficiency are crucial factors when deciding the type of light to use in an indoor aquaponics system. LED lights are energy-efficient and can last up to 50,000 hours, making them a cost-effective lighting option in the long term.

Heat Emission

The intensity of the light source will greatly impact the heat emission of the light. Some types of light, such as HID lighting, give off excessive heat, which may cause heat stress to fish.

Lifespan and Durability

The lifespan and durability of light source are crucial for keeping an indoor aquaponics system in good health. LEDs lights have both efficiency and can last up to 10 years without decreasing in intensity.


Choosing the right lighting for an indoor aquaponics system is critical to the system’s success. Fluorescent, LED, and HID lights are all viable options, each with their benefits and consideration. The most important factors to consider when choosing lighting for aquaponics systems are light intensity, spectrums, cost, efficiency, heat emission, and lifespan.


1. Can I use natural light for indoor aquaponics systems?
– Yes, it’s possible to use natural light as long as there is enough light for the plant growth stage.
2. How many hours of light do plants require in an indoor aquaponics system?
– Plants require around 12-16 hours of light depending on the growth stage.
3. Can I use regular light bulbs for indoor aquaponics systems?
– Regular light bulbs are not suitable for plant growth due to their inadequate light spectrum.
4. Which type of light is best for vegetative growth?
– Metal Halide (MH) lights are best for vegetative growth due to their blue light spectrum.
5. Can I mix different types of light in an indoor aquaponics system?
– Yes, you can mix different types of light to provide the spectrum required for plant growth at different stages.
