Wondering how to keep your plants hydrated while you’re away? Look no further! We’ve got the perfect solution for you – the low-tech, no-assembly-required long bath. That’s right, you can leave your potted plants in a sink or bathtub filled with a few inches of water, and when you come back, they’ll be nice and hydrated. So put an old towel in the tub before you fill it with water, and get ready to enjoy a worry-free vacation!

Growing Aquatic Plants in Water

Pothos is an excellent choice for those looking to have a thriving indoor plant without the hassle of soil. This houseplant is easy to grow and can be placed in water, making it ideal for novice gardeners or busy individuals who don’t have the time to tend to soil-based plants. Pothos also produces plenty of auxin, a hormone that regulates growth and stimulates root growth, which can help speed up the development of your plant.

To water your pothos, you can fill a sink, tub, bucket or any other large container with water and stand the plant in it. This method of watering is simple and effective.

The water should be changed every few days to ensure the plant gets enough oxygen. Additionally, you can add liquid fertilizer to the water when you change it, which will provide your pothos with essential nutrients.

Not all plants are suitable for water-based growth, but many varieties will thrive in this environment. Devil’s ivy, aloe Vera, spider plants, rubber plants, lucky bamboo and peace lilies are some of the most popular aquatic houseplants. These plants can be used to create a beautiful mini art installation in your home or office. They all take to water very well and require minimal maintenance to remain healthy.

However, when using tap water to water your aquatic plants, you should be aware of the potential risks. Tap water can contain chlorine and other chemicals that can be very harmful to your plants. If you use tap water, you may notice that your plants are not growing as tall and strong as they could be. Therefore, it is important to research the quality of tap water in your city before using it on your aquatic houseplants.

Another plant that can be grown in water is the Snake Plant. Snake Plants don’t necessarily need to be planted in soil to grow. They can thrive in water, pebbles, potting mixes, and water. If you are conscious of constant plant care and maintenance, you can propagate Snake Plants and leaf cuttings from the Snake Plant in water.

Growing Plants in Water: An Easy Option for Pet Owners

Other popular plants that can be grown in water include Dieffenbachia, Spider Plant, Pathos, English Ivy, Wandering Jew, Tradescantia/Purple Heart and Sanseveiria/Snake plant. All of these plants can be grown in water without soil and will do well with a little bit of maintenance. Dieffenbachia is a great choice for those who want to have an easy-care indoor plant that will grow fast. This houseplant is known to remove toxins from the air while also absorbing moisture from the air. It’s best grown in a container filled with water and gravel or pebbles at the bottom to ensure proper drainage. Spider Plants are also popular aquatic houseplants as they are low-maintenance and require minimal care once established. They prefer bright indirect sunlight but do not need much else other than regular watering when their soil starts drying out. When growing spider plants in water it’s important to change the water regularly so it does not become too stagnant or acidic for optimal growth conditions.

Furthermore, people who own cats don’t need to worry about their cat scratching up the soil in their house, as these plants can be grown without soil. This makes them an ideal choice for those with cats or other pets that may disturb the soil in a traditional pot.

When it comes to using tap water for a planted aquarium, it is important to make sure that the water has been dechlorinated and has the right parameters. Selecting aquatic plants and fish that are suitable for your tap water’s pH and KH levels is also key in order to ensure a healthy environment for your aquarium inhabitants.

Growing Houseplants in Aquariums

Using common house plants such as Pothos (Devil’s Ivy), Philodendrons, Lucky Bamboo, etc., in aquariums is a great way to help keep your water clean and healthy. These plants act like natural filters by using the dissolved minerals in the tank’s water to grow. Additionally, they can also help lower nitrate levels and provide oxygen for fish or other aquatic animals. When selecting houseplants for an aquarium environment, it is important to choose ones that are adapted to living with moisture and can tolerate being submerged in water. Some of the most popular options include Pothos (Devil’s Ivy), Philodendrons, Lucky Bamboo, Snake Plants, Dieffenbachia and Spider Plants. These plants will require regular changing of their water as well as added fertilizer if desired in order to remain healthy; however this should not be too difficult or time consuming due to their low-maintenance requirements once established. Additionally when using tap water make sure that it has been dechlorinated so it does not contain any harmful chemicals which may disrupt growth or damage your aquatic inhabitants.

Growing houseplants in water without soil can be done by cutting off a few small branches from an existing plant and placing them in a clear glass container filled with water. For a fuller appearance, multiple cuttings can be placed into the same glass. To keep the water above the root line, top up the water as it evaporates. Once the roots have grown several inches long, adding some liquid houseplant fertilization to replace any nutrients that would have been obtained from soil is recommended.

Using Aquarium Water to Fertilize Houseplants

Another option for people looking to grow houseplants without soil is to use aquarium water. If you have a large aquarium and a few plants, you can use the water to water them without the need to fertilize them. It is important to keep in mind that if you change aquarium water very frequently, the water may not be rich enough in nutrients in order for it to have the same effects as fertilizers sold in stores. Therefore, if you are considering using fish tank water for your aquatic plants, make sure that it is not changed too often or else it may lack essential nutrients needed by your houseplants for healthy growth and development. Additionally, check with an expert at a local pet store or fish supply shop before using any fish tank products on your houseplant as some products may contain chemicals which could be harmful when used outside of an aquarium environment.

Watering Houseplants: The Basics and Beyond

When it comes to watering your aquatic houseplants, the amount of time they should spend in water can vary depending on the size of their container. Generally, it is recommended to put a container in water for 15 minutes so that the soil can absorb all the water it needs. Larger containers should sit for a bit longer and smaller containers for a bit less time; however, you should keep an eye on things and add more water if needed during those 15 minutes.

If you are looking for an alternative way to water your houseplants, consider growing plants in water. This method is easy and can be done with a variety of plants, such as wandering jew plant and peace lilies. To begin, cut stem pieces that are five to seven inches long just below the leaf node where roots will develop. Place them in a jar or vase of clean water and change it every few weeks.

However, despite the fact that some plants will root in water, cuttings will develop a stronger root system when rooted in a soil-free potting soil. Cuttings that need good drainage and may rot if kept too wet can use sand or perlite.

For heavier rooting plants, the rooting process usually takes 3-4 weeks and when the roots are 1-2 inches long, they are ready to be potted up in soil.

It is important to note that roots can rot in water, as root rot is the decay and rot of plant roots caused by a lack of Oxygen in the Growing Substrate. The submersion of roots in water with little oxygen causes them to suffocate and drown like humans.

Low-tech Solutions for Watering Houseplants While Away from Home

If you don’t want to move your plants for watering, there are other options. You can water your plants in a sink or use non-draining pots with a controlled watering method. A self-watering pot, watering spike or using ice cubes are all viable options that can help you keep your plants watered without having to move them from their current location. A self-watering pot is one of the easiest and most efficient ways to keep houseplants hydrated without having to worry about moving them for regular watering sessions. These pots come equipped with a water reservoir which slowly releases water over time, providing the plant with enough moisture until it’s time for another refill. Watering spikes are also great tools if you have multiple potted plants around your home that need frequent and consistent hydration but cannot be moved easily. These spikes fit into bottles filled with nutrient solutions and slowly dispense the solution directly into the soil of each individual potted plant as needed – making it an effective way to care for several indoor plants at once without lifting a finger! Finally, using ice cubes is another way of keeping houseplants hydrated without any fuss or mess. This technique involves simply adding two to three small ice cubes per day directly on top of the soil in each houseplant’s container; this will melt slowly over time and provide enough moisture until it’s time for more ice cubes! It is important to note that when using these methods, too much water can cause root rot in some cases so make sure not to overwater – adjust accordingly depending on how much sunlight and heat exposure each individual plant receives daily as this will greatly affect its need for moisture levels.

The long bath is a great low-tech solution for watering plants while away from home. Place the pots on top of the tub after laying an old towel in it to protect it, then fill the tub with a few inches of water and you’re ready to go!

The soil will draw up the water and keep your plants hydrated while you’re away.


Growing plants in water is a great alternative to traditional soil-based gardening and is an easy way to keep your houseplants healthy. While it is possible for some plants to survive in just water, it is important to consider the water parameters and quality of your tap water before attempting to grow plants in water. If you have the right environment, this method can produce stunning results.
