Peace Lilies

Peace lilies are beautiful house plants in most locations. Although they can grow outdoors in tropical or humid climates, for most of us, they are indoor plants.

They are great house plants because they are a kind of plant that is low maintenance and requires easy care. They are one of the most popular indoor plants and can be found in most nurseries, greenhouses, or even home stores like Home Depot, Lowe’s, Menards, and some grocery stores.

These are beautiful plants, having mostly dark green leaves accompanied by white blooms.

Common Name

Although peace lilies are the common name for these plants, they are also part of the species of spathiphyllum.

These plants have other common names such as white sails, or spathe flowers. Peace lilies receive these other names first because of the white flowers that they produce, which often look like white sails.

They have also been dubbed the name sympathy flower because these plants are commonly given as gifts at funerals for the family of the deceased. This helps the family to have something living to care for as a way of remembering their departed loved ones.

Hydroponic Plants

Many different varieties of plants can be grown as hydroponic plants in a hydroponic system. In most cases, the hydroponic system does not have to be elaborate or complicated. In this case, you can easily grow a peace lily plant, in a jar of water, with some liquid fertilizer.

Should You Grow Your Peace Lily in Water?

Just because you can do something, doesn’t always mean that you should do it. Although peace lilies can be grown in water, is it actually a good idea to throw them in water?

There are several different reasons why you might choose to grow peace lilies in water. First of all, you don’t have to worry about finding soil, a pot it fits in that matches your décor, and remembering to water it.

But, when you grow a peace lily in water, it will typically limit how large the plant grows. Plus, there are specific types of water that are better than others for it to grow in. You will also need to remember to fertilize the peace lily in water so that it continues to grow and stays healthy.

When peace lilies are grown in water, they do run the risk of growing roots that aren’t quite as strong and may sometimes even encounter root rot.

There are pros and cons both to growing a peace lily in hydroponic systems, as well as growing a peace lily in the dirt. Essentially, it all comes down to what your preference is, and what best fits your lifestyle.

If you decide to grow your peace lily as an aquatic plant, here is the best way to go about doing it as well as everything you will need to know and have on hand. Let’s check it out!

Glass Container

Before you begin transitioning your peace lily into a hydroponic system, you will first want to find an appropriate glass container for your peace lily to grow in. Ideally, you want to have a tall glass container such as a vase or a jar.

Plastic Stopper

You will also want to find a plastic stopper that will hold your peace lily inside the glass container. This is important because the job of the plastic stopper is to help hold the peace lily at the top of your container so that the plant doesn’t completely submerge.


Water is another essential part of planting peace lilies in a hydroponic system. There are many different types of water available. Some of these include tap water, distilled water, fresh water, spring water, rain water, and bottled water.

But what is the best type to use for hydroponic peace lilies? Rather than using basic tap water for peace lily water, the best type of water you can use is distilled water.

If you have distilled water as an option, then it is a very good idea to keep this on hand for the hydroponic peace lily plants.

Water Line

Not only is it important to know what type of water to use, but it is also very important to know how much water to include in the peace lilies.

Ideally, you want the water level at the base of the plant. If there’s too much water, it can cause the plant to struggle.

To keep the peace lilies nice and happy, it is best to change the water on a bi-weekly basis, refilling the water to the water line, using distilled water.

Drops of Liquid Fertilizer

It is also a good idea to have some liquid fertilizer on hand. Adding a drop every once in a while, into the water for your peace lily will help keep the plant happy and healthy. They don’t need much fertilizer, but enough to keep them healthy is good.

Root System

As the peace lily is submerged in water, you can observe the roots of the peace lily. The plant will also have new growth of the roots that are more sustainable in water.

Indirect Sunlight

Peace lily plants must be kept in indirect sunlight. These plants will thrive the best when they are in indirect light rather than bright direct sunlight. Ideally, they can be kept in an east or west facing window. It is important that they don’t have too much sunlight, but enough light to keep them healthy.

Now that we have covered what is required for growing hydroponic peace lilies, let’s look at the step-by-step guide to growing peace lilies in water.

Growing a Peace Lily in Water: Your Step-by-Step Guide

Step 1: Prepare the Container

First, begin by preparing your container. This means you want to find an appropriate glass container, with a plastic stopper, and fill it part of the way with distilled water.

Step 2: Uproot the Peace Lily

After the hydroponic setup is ready, take your peace lily plant, and gently remove it from the dirt. When doing this process, you must be very gentle with the roots. You can rinse the plant off in the water, before placing it into the glass jar.

Step 3: Transfer the Plant

After the soil has been completely removed from your peace lily plant, place it into the glass jar or vase, using the plastic stopper to keep the plant from falling completely into the water.

Step 4: Get the Peace Lily in Place

Arrange the plant, so that the glass jar is filled most of the way with distilled water, covering the roots, but the stem and green portion of the plant are left in the air. Find a nice warm spot with indirect sunlight to set the hydroponic peace lily.

Step 5: Long-Term Care

Change the water in the hydroponic peace lily every couple of weeks (or bi-weekly). Make sure to replace the water with distilled water each time. Then, on occasion, add liquid fertilizer into the water to help strengthen the plant.

Potting in Soil

A peace lilly can also be transferred from hydroponic plants and planted back into potting soil if desired. As mentioned above, there are pros and cons, to growing peace lilies in water, and soil.

When peace lily plants are planted back into the soil, you will first want to select a new pot. The pot must be large enough for the plant to fit in, but not excessively large in size.

Then select a potting mix with good drainage, but also one that can keep the plant in moist soil. Water the plant occasionally to keep it moistened.

The peace lily plant is historically a tropical plant, and it loves high humidity levels, as well as warm temperatures. Keep the potted peace lily in indirect sunlight, such as an east or west-facing window. Fertilizer can be used occasionally to feed the plant as needed.

Signs that Peace Lily is Unhappy

No matter, if you are a peace lily, is in a hydroponic system, or is planted in soil, there are a few different signs you will want to keep an eye out for, to know if the peace lily is struggling, or unhappy.

These different signs that you can watch out for include brown spots on the plant’s leaves, brown leaf tips on the leaves, and root rot.

New Plants Propagation

To propagate peace lilies, they are typically multiplied by using two methods. The most common way to propagate peace lily plants is by dividing plants.

To do this, a parent plant is divided into smaller portions and separated into different pots. These separated plants, then grow larger and make new plants in and of themselves.

The second way peace lilies can be propagated is by using seeds. Although this is a less common method, seeds can be planted, to create new baby plants.

Hydroponic Peace Lily with Beta Fish

That idea has been suggested that hydroponic peace lilies can be grown in a beta fish tank or fishbowl. This is suggested because it is thought to create a self-sustaining ecosystem. In the suggested ecosystem, beta fish eat the roots of the peace lily, and the fish’s poop serves as fertilizer for the peace lily plant.

Although it sounds like a great plan in theory, it is not likely to work out in reality. Beta fish are carnivorous and can’t survive on roots alone. For this to be a real possibility, the fish would need to be fed with fish food and kept in water that is at least 80°F. Beta fish also need exposure to air.

This means that the peace lily could not take up the entire opening of the tank, and would need to be restricted, to only taking up a portion of the opening so the fish could still be exposed to air circulating through the top.

Beta fish also need a large amount of water to survive. At the low end, they need 2 ½ gallons of water to live.

Although in theory, this sounds like a great idea to have beta fish and hydroponic peace lilies all in the same hydroponic system, it is not highly likely to succeed in real life.

Semi-Hydroponic Peace Lily Growing System

Another option for growing peace lilies is to use a semi-hydroponic growing system. To do this, the supplies that are needed include a light absorbent and porous material that will hold the moisture and allow the plant to grow in it.

In a semi-hydroponic system, the water is pulled from the bottom of the container and absorbed into the material surrounding the plant. This lets you have the convenience of a peace lily growing in water, but the plant will likely develop soil roots rather than fragile water roots.

How to Grow a Semi-Hydroponic Peace Lily

To grow a peace lily in a semi-hydroponic system, first, select a net pot and absorbent soil medium.

Then, plant the peace lily in the medium. Place the netted pot in a pot above water, and water occasionally. Place the semi-hydroponic peace lily in indirect sunlight, in a warm location.
