How dehumidifiers can improve your hydroponic growing system

Among the most important variable in growing plants indoors is having the right humidity level. Ionmax dehumidifiers are able to regulate humidity levels all year round, ensuring a healthier hydroponic growing system.

Hydroponics is a method of growing plants without soil. Instead, a water-based nutrient solution is used. In recent years, this method of farming has become popular, especially in areas where conventional farming methods are not feasible due to space, or environmental limitations, a problem faced by many urban farmers.

In hydroponics, plants are grown in a controlled environment where temperature, humidity, light and nutrients are carefully regulated.

Maintaining ideal humidity levels is a crucial factor in successful hydroponic cultivation. High levels of humidity can cause mould and mildew to grow and spore, which could damage and kill the plants.

This is where dehumidifiers come into play. Ionmax dehumidifiers efficiently regulate humidity levels in hydroponic growing systems.

Benefits of using dehumidifiers for hydroponic growing systems

Overall, dehumidifiers can play a crucial role in ensuring optimal growing conditions for hydroponic plants which can result in healthier plants, higher yields and even reduced costs. Some of the benefits of using dehumidifiers in hydroponic setups include the following:

Prevents mould and mildew growth

When mould grows in a certain space, it spreads through the release of tiny mould spores which could settle on plants, potentially blocking the plant’s stomata, the small openings on leaves that help with respiration. Blockage of the stomata can cause poor respiration, decreased photosynthesis, and eventually stunted growth, wilting and yellowing of the leaves.

When dehumidifiers regulate humidity levels, it creates an environment less conducive to the growth of mould and more conducive to ideal hydroponics.

Improved plant growth and yield

High levels of humidity can lead plants to experience too much stress, which in turn, stunts their growth. Additionally, if there are already high levels of moisture in the air, the transpiration process may be disrupted, which can lead to waterlogging and suffocation of the plants.

Dehumidifiers help regulate and remove excess moisture from the air to help prevent these issues.

Easier humidity control

Ionmax dehumidifiers provide customers with an easy and cost-efficient method to control humidity levels within your hydroponic growing system. Simply plug your unit in, select your preferred humidity level and start running the unit. Optimal humidity ranges are between 45% to 85% depending on the crop that is being grown.

Humidity levels should gradually decrease as your plant matures. Selected Ionmax dehumidifiers come with a mobile phone pairing, allowing users to change the settings of their dehumidifiers remotely.

Saves energy and reduces costs

Dehumidifiers can help to reduce the load on air conditioning systems, which can result in significant energy savings while reducing power bills. By using a dehumidifier to maintain ideal humidity levels, you can create a more efficient growing system.

Factors to consider when choosing a dehumidifier for hydroponic setups

Below are some key factors to consider when choosing a dehumidifier for your hydroponic setup:

Space size

Not all dehumidifiers were created equal. Some dehumidifiers are able to extract moisture from larger spaces compared to others. Generally, industrial dehumidifiers possess a higher extraction rate and coverage area compared to others. For optimal performance, ensure that the dehumidifier you look to be purchasing has a coverage area that suits your hydroponic setup.

Drainage options

Most dehumidifiers come in with a built-in tank or reservoir that collects the moisture extracted from the air. Once the tank is full, users will need to manually empty the tank for dehumidification to resume. All Ionmax dehumidifiers are equipped with collection tanks and also come with a continuous drainage option, where users attach a hose to the unit’s water outlet and connect it to a larger container or a drain so that they need not worry about emptying any tank.


Choose a dehumidifier that is built to last, with strong and durable construction, this ensures that your unit will be able to handle the demands of your hydroponic system. Knowing that your dehumidifier is protected is bound to give you better peace of mind. All Ionmax residential dehumidifiers come with an extended 4-year warranty.


The climate that you live in has a direct impact on the kind of dehumidifier that you can choose to purchase, as some dehumidifiers are able to work better compared to others depending on the technology used. Desiccant dehumidifiers are known to be more energy efficient in cold climates and can be used all year round, whereas compressor dehumidifiers work more efficiently in warmer climates
