From soil to water: the new way to grow tropical plants
Growing tropical plants in water means using hydroponics, a soilless technique in which the roots are kept in water or an inert substrate such as expanded clay, perlite, or vermiculite, and nutrients are delivered dissolved in the water. Monstera adapts well to this method, which makes the roots visible and reduces soil-borne pests.
The transition from traditional soil cultivation to growing in water marks a true revolution for tropical plant enthusiasts. This transition not only meets contemporary aesthetic needs but also offers practical solutions to many of the common challenges of indoor gardening. Hydroponic cultivation, once confined to greenhouses and laboratories, is now accessible to everyone, making it possible to create lush, easy-to-manage green spaces.
What is hydroponics?
Hydroponics is a soilless cultivation technique in which plants grow with their roots immersed directly in water or in an inert substrate, such as expanded clay (LECA), perlite, or vermiculite. Unlike soil cultivation, where the soil acts as a reservoir of nutrients, in hydroponics the water itself carries all the nutrients the plant needs. When properly managed, this aquatic environment enables optimal nutrient absorption and constant oxygenation of the root system, key elements for healthy, vigorous growth.
Why grow Monstera hydroponically?
Monstera, with its iconic split leaves, adapts surprisingly well to hydroponic cultivation. Its aerial roots, which in nature allow it to climb and absorb moisture from the environment, demonstrate a remarkable ability to adapt to an aquatic environment. Growing hydroponic monstera means providing it with a controlled environment where nutrients can be precisely measured, soil-borne pests can be prevented, and problems related to incorrect watering, such as root rot, can be drastically reduced. In addition, the transparency of glass containers makes it possible to admire the fascinating development of the roots, adding another element of decorative interest.

The benefits of growing Monstera in water
Growing Monstera in water ensures a constant and even water supply, eliminates the habitat of many soil-dwelling pests and fungi, and makes it possible to provide easily absorbable liquid nutrients. The result is faster growth, larger leaves, and more intense color, with techniques ranging from simple DWC to the drip system.
Choosing to grow Monstera in water is not just a stylistic choice, but a decision that brings a range of tangible benefits for the plant's health and growth. This innovative method creates an optimal environment that promotes lush development and minimizes stress for the plant, making its care a simpler and more rewarding experience.
How hydroponics improves the health of your Monstera
Hydroponics positively affects the health of Monstera in several ways. First of all, it ensures a constant and even water supply, eliminating the cycle of
drought and excess water, which often causes stress and root rot in traditional cultivation. In addition, the absence of soil eliminates the ideal habitat for many pests and fungi, naturally protecting the plant. The ability to provide nutrients in liquid, easily absorbable form allows the Monstera to absorb exactly what it needs, when it needs it, promoting faster growth, larger leaves, and more intense color.
Monstera in hydroponics: care and main techniques
To delve into the world of hydroponic Monstera, it is useful to know the main cultivation techniques. Although complex systems exist, it is possible to start with simple methods accessible to everyone. Caring for and managing hydroponic Monstera varies slightly depending on the system chosen.
1.Deep Water Culture (DWC): This is one of the simplest and most effective techniques to get started. The plant's roots are suspended in a container filled with a nutrient solution that is constantly oxygenated by an air pump. This method ensures optimal root oxygenation, preventing rot and stimulating explosive growth. It is the ideal choice for those who want quick results with a limited initial investment.
2.Nutrient Film Technique (NFT): In this system, a thin film of nutrient solution constantly flows along an inclined channel, touching the plant's roots. NFT is a recirculating system that ensures excellent oxygenation and a continuous nutrient supply. Although it is more technical than DWC, it is extremely efficient and is often used in commercial cultivation because of its high productivity.
3.Drip system: This method involves delivering the nutrient solution directly to the base of the plant through drippers. It is a highly versatile system that can be used with both inert substrates (such as expanded clay) and bare-root systems. The drip system allows precise control over the amount of nutrients supplied and can easily be automated, making it a convenient, low-maintenance solution.

How to get started? First steps in hydroponics with Monstera
To get started, you need a glass or hydroponic container, thoroughly rinsed expanded clay, liquid hydroponic fertilizer, and water that has been left to stand for 24 hours. Remove all the soil from the roots, position the plant with the expanded clay, and fill with water to about one-third of the roots; alternatively, start with a cutting that has a node.
Starting your own Monstera in hydroponics is a simpler process than you might think. With the right materials and a little care, you can successfully transfer your plant from soil to water, or start from scratch with a cutting. This chapter will guide you through the first essential steps to begin your hydroponic journey.
Products for effective hydroponic cultivation of Monstera
Before getting started, it is important to obtain everything you need. Choosing the right products is essential to ensure the plant has a healthy and stable environment. Here is an essential list:
•Container: A transparent glass vase is ideal for getting started, as it allows you to monitor root growth and the water level. Alternatively, you can use containers specifically designed for hydroponics, often equipped with a water-level indicator.
•Inert substrate: Expanded clay (LECA) is the most common and recommended substrate. Its porous balls support the plant, retain moisture, and promote root oxygenation.
•Liquid fertilizer: It is essential to use a complete and balanced fertilizer specifically designed for hydroponic cultivation. These products contain all the necessary macro- and micronutrients that the plant can no longer obtain from the soil.
•Water: Tap water is generally fine, but it is advisable to let it stand for 24 hours to remove the chlorine. Rainwater or distilled water are excellent alternatives.
Preparing the container and substrate
Once the material has been gathered, preparation is simple. If using expanded clay, it is essential to rinse it thoroughly under running water to remove dust and impurities. This step prevents the water in the pot from becoming cloudy. The container must be cleaned and sanitized to prevent the proliferation of bacteria or algae. A layer of expanded clay can be placed at the bottom of the pot to serve as a support base for the plant.
Drainage system and plant supports
Although it may seem counterintuitive, good drainage is also important in hydroponics, especially in systems with a substrate. Hydroponic pots have a double bottom that creates a water reservoir and keeps the roots elevated, preventing them from remaining constantly submerged and promoting oxygenation. For larger Monsteras, it is useful to provide a stake or moss pole, inserted into the container before the plant, to guide its vertical growth.
Transferring a Monstera to water (including via a cutting)
The transfer is the most delicate stage. If starting with a plant in soil, carefully remove it from the pot and clean all the soil from the roots, rinsing them thoroughly under lukewarm water. This is an excellent opportunity to inspect the root system and prune any dry or damaged roots. At this point, the plant can be placed in the new container, adding expanded clay to stabilize it. Finally, fill the pot with water until approximately one third of the roots are covered.
An excellent alternative is to start with a Monstera cutting in water. By taking a section of stem with at least one node and one aerial root, you can place it directly in a vase with water. The roots that develop will already be adapted to the aquatic environment, making the rooting process much faster and more reliable. This technique is ideal for propagating your Monstera and starting hydroponic cultivation without stress and without necessarily having to convert an adult plant.
Water management in hydroponics for a healthy Monstera
In hydroponics, water should initially be managed by keeping the level low, which encourages the roots to grow downward, checking the pH weekly, ideally between 5.5 and 6.5, replacing the nutrient solution every 10-14 days with top-ups of dechlorinated water, and using specific liquid fertilizers at reduced strength in autumn and winter.
Careful water management is the fundamental pillar of success with Monstera in hydroponics. Unlike soil, water is an environment that requires constant monitoring to ensure that the roots receive the right balance of hydration, nutrients, and oxygen. Mastering water management means ensuring your Monstera a long and thriving life, protected from the most common risks of this type of cultivation.
Techniques for growing roots in a water-based substrate
Encouraging healthy root growth is the first step. When a plant is transferred from soil, its roots must adapt to the new environment. Initially, it is advisable to keep the water level lower, covering only the lower part of the root system. This encourages the roots to grow downward in search of water, developing a stronger and more resilient system. Using a substrate such as expanded clay provides physical support and maintains constant moisture around the upper roots, facilitating the transition.
Monitoring water quality: ideal pH and level for Monstera
Water quality is crucial. Two parameters are fundamental: pH and nutrient concentration. The ideal pH for nutrient absorption by Monstera is in a slightly acidic range, between 5.5 and 6.5. It is advisable to check the pH weekly with suitable test kits or digital meters and adjust it, if necessary, with specific products (pH- or pH+). An incorrect pH can block the absorption of essential elements, even if they are present in the water, leading to nutrient deficiencies.
How often should the water be changed in hydroponics?
The frequency with which to change the water depends on various factors, such as the size of the container, the size of the plant, and the ambient temperature. As a general rule, it is best to replace the nutrient solution completely every 10-14 days. This prevents mineral salt buildup, keeps the water fresh and oxygenated, and restores the nutrient balance. Between changes, simply top up the water level with dechlorinated water to compensate for evaporation.
Effective liquid fertilizers
In hydroponics, fertilization is not optional but a necessity. It is essential to choose liquid fertilizers specifically for hydroponics, as they contain a complete profile of balanced macro- and micronutrients for plants grown without soil. Carefully following the manufacturer's dosage instructions is essential to avoid burning the roots. During the growing season (spring-summer), fertilization will be more frequent, while in autumn-winter it can be reduced or suspended.
Monstera care: problems? Here are some tips
The most common problems with Monstera in hydroponics are nutrient deficiencies, which can be identified by leaf color, root suffocation, with brown and soft roots caused by poor oxygenation, and yellow leaves. They can be addressed with a complete hydroponic fertilizer, the correct pH, more frequent water changes or an air pump, and pruning the damaged roots.
Even when grown hydroponically, Monstera can show signs of distress. Learning to recognize them and intervene promptly is key to keeping the plant perfectly healthy. Caring for hydroponic monstera requires a watchful eye, but solutions to the most common problems are often simple and straightforward.
Solutions for common nutrient deficiencies in hydroponics
Nutrient deficiencies usually appear as changes in leaf color. Leaves that turn yellow starting at the edges may indicate a potassium deficiency, while yellowing between the veins (which remain green) is often a sign of magnesium or iron deficiency. The solution is to use a complete and balanced hydroponic fertilizer and ensure that the water's pH is within the optimal range to allow all nutrients to be absorbed.
Signs of water stress
Although the plant lives in water, water stress is possible. Roots that turn brown and soft are a clear sign of root suffocation caused by poor water oxygenation. This happens when the water is not changed frequently enough or when there is no aeration pump. To solve this, change the water immediately, prune the damaged roots, and increase the frequency of water changes or install a small air pump.
Common Monstera problems: yellow leaves and rotten roots
Yellow leaves are the most common symptom and can have multiple causes. If only the lowest and oldest leaves turn yellow, this is a normal senescence process. If the yellowing is widespread, it could be excessive fertilizer or, as seen, root suffocation. Rotten roots, on the other hand, are an unmistakable warning sign: the root environment is unhealthy. It is essential to act immediately by cleaning the root system and improving oxygenation.
Automatic monitoring of plants in hydroponics
For those who want even more precise and less demanding control, automatic monitoring systems are available. pH and EC sensors (electrical conductivity, which measures salt concentration) can provide real-time readings, while automated control units can dose fertilizers and pH adjusters, keeping the nutrient solution perfect at all times. Although they represent an investment, these systems greatly simplify managing monstera in hydroponics.
Regular maintenance of Monstera in hydroponics
In addition to changing the water, regular maintenance includes cleaning the container of any limescale or algae deposits and pruning dry or damaged leaves. It is also good practice to rotate the plant periodically to ensure even exposure to light and harmonious growth. Every 2-3 months, more thorough washing of the roots and substrate under running water is recommended.
Common Mistakes in Home Hydroponics
The most common mistakes in home hydroponics concern environmental conditions: exposing Monstera to direct sunlight, which burns the leaves and warms the water, encouraging algae; giving it too little light; keeping it below 15°C or in dry air; leaving it in cold drafts; and submerging the cuttings too deeply, as their leaves must remain above the water.
Starting hydroponic cultivation can be exciting, but it is easy to run into some common mistakes, especially at the beginning. Knowing these pitfalls is the best way to avoid them and provide your Monstera with an ideal growing environment. Most mistakes concern managing environmental conditions, which are just as important as water quality.
Ideal location for healthy Monstera growth indoors
Choosing the right location is crucial. Monstera loves light, but not direct sunlight. Ideally, place it in a very bright environment, sheltered from direct sunlight, which could burn the leaves and overheat the water in the container, encouraging algae growth. An east- or north-facing window is often an excellent choice.
Direct, indirect, or artificial light?
The best light is bright, indirect light. If natural light is insufficient, it can be supplemented with grow lights. When selected with the correct spectrum, these artificial lights can fully compensate for the lack of sunlight, allowing you to grow Monstera even in dark corners of the home. The important thing is to ensure a photoperiod of at least 10-12 hours per day.
Temperature and humidity for Monstera in hydroponic cultivation
As a tropical plant, Monstera thrives in warm, humid environments. The ideal temperature is between 18°C and 27°C. It suffers in temperatures below 15°C and from sudden temperature changes. Ambient humidity should be high, ideally above 60%. If the air at home is dry, it is helpful to mist the leaves with lime-free water or use a humidifier.
Air currents: pay attention to Monstera's leaves!
Cold drafts are the enemy of Monstera. Avoid placing it near windows that are frequently opened in winter or in front of air conditioners. Constant air currents can quickly dehydrate the leaves and cause thermal shock to the plant, compromising its health.
Supports for Monstera cuttings
When placing a Monstera cutting in water, it is important to provide adequate support. The cutting should not be completely submerged; only the node and aerial root should be immersed. You can use special perforated lids for hydroponic cultivation, or simply supports that keep the cutting upright, ensuring that the leaves always remain above the water.
Pruning to care for Monstera in hydroponic cultivation
Pruning is an important aspect of care. It not only removes dry or damaged parts, but also helps control the plant's shape and size. Always prune above a node, using clean, disinfected pruning shears. Pruning also stimulates the plant to produce new shoots, making it fuller and more compact.
Hydroponics and sustainability
Choosing hydroponics is not only a matter of aesthetics or practicality, but also a step toward more sustainable gardening. This cultivation technique offers significant environmental benefits. The most significant is water conservation: recirculating hydroponic systems can significantly reduce water consumption compared with growing in soil. In addition, by eliminating the need for potting soil, it helps preserve peatlands, valuable and threatened ecosystems. The absence of herbicides and the drastic reduction in pesticides make cultivation cleaner and safer, both for the home environment and the planet.
