So, let’s dive into the world of peace lily hydroponics and create your own thriving indoor oasis.


Hydroponics has gained immense popularity in recent years, offering a unique way to grow plants without traditional soil. This soil-less method provides numerous benefits, including efficient nutrient absorption, controlled environments, and the ability to grow plants indoors year-round. Among the many plants suitable for hydroponics, peace lilies stand out as a favorite choice for indoor gardeners. Their lush foliage and elegant white flowers make them a captivating addition to any home or office space.

Peace Lily Hydroponic: A Step-by-Step Guide

Requirements for Growing Peace Lilies Hydroponically

To ensure successful growth, peace lilies have specific requirements when it comes to lighting, temperature, humidity, and nutrients.

Lighting needs

Peace lilies thrive in bright, indirect light. They prefer a minimum of 12 to 16 hours of light per day. LED grow lights or fluorescent lights are excellent options for providing the necessary light intensity without overheating the plants.

Temperature and humidity considerations

Maintaining a temperature range of 65 to 85°F (18 to 29°C) is ideal for peace lilies. Additionally, these tropical plants appreciate high humidity levels of around 50-70%. Using a humidifier or placing the hydroponic setup in a naturally humid environment, such as a bathroom, can help create the perfect conditions.

Nutrient requirements

Peace lilies require a balanced nutrient solution to thrive. The key macronutrients to include in the solution are nitrogen (N), phosphorus (P), and potassium (K), which can be found in hydroponic-specific nutrient mixes. Additionally, peace lilies benefit from micronutrients such as iron (Fe), magnesium (Mg), and calcium (Ca).

Setting Up a Hydroponic System for Peace Lilies

Now that we understand the requirements, let’s walk through the process of setting up a hydroponic system for peace lilies.

Choosing the right container

Select a container that is suitable for hydroponics, such as a reservoir or a grow tray. Ensure the container is large enough to accommodate the peace lily’s root system and allow space for the nutrient solution.

Selecting the appropriate growing medium

In hydroponics, the growing medium serves as a support system for the plants’ roots. For peace lilies, options like rockwool, coco coir, or perlite can be used. These media retain moisture while providing ample aeration for the roots.

Establishing the water and nutrient solution

Prepare the nutrient solution by following the manufacturer’s instructions on the hydroponic nutrient mMeasure and mix the appropriate amount of nutrients with water, ensuring the solution’s pH level falls within the optimal range of 6.0 to 6.5.

Transplanting the peace lily

Gently remove the peace lily from its current pot, being careful not to damage the roots. Place the plant in the chosen growing medium and adjust the medium to securely hold the plant in place. Ensure the roots are properly covered while maintaining access to oxygen.

Maintenance Tips for Peace Lilies in a Hydroponic Setup

To ensure the well-being of your peace lilies in a hydroponic setup, it’s crucial to provide proper maintenance and care.

Monitoring pH levels

Regularly monitor the pH level of the nutrient solution using a pH meter or test strips. Adjust the pH level if necessary, as fluctuations can affect nutrient absorption and plant growth. Most peace lilies prefer a slightly acidic pH level between 5.8 and 6.5.

Adjusting nutrient concentration

Monitor the nutrient concentration in the solution using an electrical conductivity (EC) meter. Adjust the nutrient concentration periodically based on the growth stage of the peace lily. Younger plants require lower nutrient concentrations, while mature plants may need higher levels.

Regular cleaning and sterilization

To prevent the buildup of algae, bacteria, or fungi in the hydroponic system, it’s important to clean and sterilize the equipment regularly. Empty and clean the reservoir, replace the nutrient solution, and clean the growing medium to ensure a healthy environment for your peace lilies.

FAQ about Peace Lily Hydroponics

Can peace lilies thrive without soil?

Absolutely! Peace lilies are well-suited for soil-less cultivation, thriving in a hydroponic system where they receive the necessary nutrients directly through the water.

How often should I change the nutrient solution?

As a general guideline, it’s recommended to change the nutrient solution every two to three weeks. However, ensure you monitor the solution’s pH and nutrient concentration regularly to determine if an earlier change is required.

What are the most suitable lighting options?

For peace lilies grown hydroponically, LED grow lights or fluorescent lights are ideal choices. These lights provide the right spectrum and intensity for optimal growth without generating excessive heat.

Can I use tap water for my hydroponic peace lilies?

Using tap water for hydroponic systems is possible, but it’s important to check its quality. Tap water often contains chlorine, chloramines, or high mineral content, which can negatively impact plant health. If necessary, consider using filtered or distilled water to ensure the best results.

What are the potential challenges and how to overcome them?

Common challenges in hydroponic peace lily cultivation include over or underwatering, nutrient imbalances, and pest infestations. By closely monitoring the plant’s growth, maintaining proper watering and nutrient levels, and implementing preventive measures against pests, you can overcome these challenges and ensure healthy plant growth.


In conclusion, peace lily hydroponics offers an exciting and efficient way to grow these stunning plants indoors. By following our step-by-step guide, you can create a thriving hydroponic system for your peace lilies, providing them with the ideal environment to flourish. Remember to monitor lighting, temperature, humidity, and nutrient levels, ensuring your peace lilies receive the care they deserve.
