Depending on the type of plant and the stage of development, different plants require different degrees of humidity. The amount of humidity you need can also depend on the weather or your living situation.
The majority of indoor plants, including the Parlor Palm, Pothos, English Ivy, Begonia, Ferns, Ficus plant, Peace Lily, Philodendron, Areca Palm, and Orchid plants, are native to tropical or subtropical climates. They are excellent air-purifying plants and are known to maintain the quality of the air in your home.
It rains a lot in tropical locations, and the summers are hot and muggy. Around 70–90% humidity is what they encounter. Most dwellings, in contrast, have very low humidity levels. Particularly during the winter, when heating systems remove moisture, causing humidity levels to fall to 20% or even lower.
Conversely, other plants, like the majority of succulents, can easily survive at low humidity levels of around 10%. Most indoor plants can flourish in humidity levels of 40 to 60 percent on average. Here is a list of different humidity levels and the plants that may like them:
0% – 20%: While the air is too dry for most houseplants at this level, cacti or succulents can live down to about 10% lowest.
For most interior locations, the humidity will be between 20 and 40 percent. While some plants, particularly those from tropical regions, will survive, others won’t blossom, leading to droopy leaves.
This humidity range, between 40 and 60 percent, is appropriate for most homes in the summer and for most plants to grow well. Other plants can readily survive when humidity is increased in specific methods, such as sprinkling. The optimal level for flowering and vegetation is likewise at this level.
This humidity range, while is ideal for a greenhouse, can be challenging and uncomfortable to maintain at home. It works best with tropical plants.
80 percent +: Tropical plants like pineapples demand extremely high humidity levels of 90 percent, which is impossible at home. Additionally ideal for seed germination and seedling development, this level.
What humidity level is ideal for houseplants?
Consider yourself a house plant. You are developing in a greenhouse with a high humidity level. You are relocated from this comfortable setting to a new residence with an air conditioner that blows frigid air and absorbs moisture. The heater keeps the air dry and warm during the winter. Your leaves begin to develop browning edges and tips with yellowing leaves as a result. You quickly start to wilt, and your foliage starts to turn crisp. Furthermore, why are these red spider mites eating the juice from your stems? Your body is asking for more humidity for the houseplants through these symptoms. quite similar to what your motherland offered you in the tropical rainforest!
Most people’s houses don’t resemble a rainforest with 100 percent humidity, but you may create a simple rainforest-like alternative and raise the humidity for your indoor plants. Humidity is another important consideration in addition to meeting your plant’s needs for water, light, and temperature. To thrive in their new surroundings, they require it. When purchasing and caring for indoor plants, many plant owners fail to take this aspect of the plant equation into account.
Give your plant a shower when you had it for a few months. During your weekly watering rituals, repeat this. Fill a watering can with this to begin. To give chemicals time to evaporate, use filtered water, room-temperature rainwater, or water from your tap that has been sitting for 24 hours (chlorine or fluoride). Put your plant in the shower or bathtub and water it (except for plants with hairy leaves like African violets). This shower will remove any dust and debris in addition to raising the humidity. Place it back in its resting area after letting it air dry.
The humidity levels for your indoor plant will be increased if you set up a pebble tray underneath it to allow water to evaporate up around it. To do this, gather a plate that is a little bit bigger than the size of your pot. Use an 8-inch plant tray if your pot is 6-inches, for example. A couple handfuls of clean pebble gravel or vibrant glass fire marbles will fill the dish; add just enough water to cover the stones. Place the planter on top of the stones. In addition to maintaining appropriate drainage, the stones will offer the container that extra boost of humidity needed for the indoor plant. Keep an eye on the dish’s inclination to evaporate and how often you need to replace it. More frequently than you might anticipate!
You can also add a hand mister to your indoor plant as a supplement. Use only filtered water, rainwater, or water that has sat overnight to allow all of the contaminants in city water to dissipate. To give your plant that extra boost of humidity, mist it many times throughout the day. Be extra cautious in locations where the mist can end up on drapes, upholstery, or wooden furniture. If this is the case, spread out a bath towel, set the plant on it, spray it, and then put it back where it was. This will prevent damage to your surrounds, and your plant will be overjoyed to have that layer of moist dew on its leaves.
Plant clustering raises the air’s humidity level. The temperature in the room rises when people congregate, and the same is true for your green-leafed babies. Their stalks, flowers, and leaves all exude. As a result of this process, the other plants in the area will have humidity. When it comes to raising the humidity levels, they prefer a crowd, so to speak, and the more the merrier. Through this fascinating process, the environment and the leaf are exchanging vapor to aid each other’s humidity rise while also absorbing carbon dioxide.
Use a humidifier set to warm mist if you have a group that prefers greater humidity levels. Fill your humidifier with distilled or filtered water. This warmth also resembles the rainforest, which is its native habitat! To enhance the amount of moisture in the air for your indoor plants, place it all around the group of plants. To determine your current level of humidity and when it is too low for your indoor plants, use a hygrometer. For the majority of tropical indoor plants, maintain a humidity level of 50 to 60 percent. (The humidity in a typical home hovers around 30 to 40 percent.) Just be mindful of your surrounds and where the moisture will collect to avoid damaging nearby furniture or floors. A whole-house humidifier installation is an additional choice. Consult your HVAC provider about adding one to your system.
Another choice is to place your indoor plants in humid rooms of the house, such as well-lit bathrooms, laundry rooms, or kitchens. Your plant will like the additional steam from a shower, and another factor that increases humidity is boiling water entering the air in a kitchen. Additional moisture input, such as the humidifier option, may be necessary to maintain the humidity at a constant level.
Keep the plants that require humidity away from radiators, heat sources, and areas with radiant heated flooring. Plants can suffer if there is less moisture around them, which can happen in doorways, corridors, or places that experience wind or drafts.
You can benefit from boosting humidity for your plants by moisturizing your skin, relieving chapped lips, avoiding runny noses and scratchy throats, and avoiding dry eyes, nasal passages, and lungs. As you roam around your home throughout the winter, static electricity will also lessen. Therefore, having the right amount of moisture in the air can aid in treating asthma, allergy, and sinus issues. Of course, consult your physician before using a humidifier.
What are you still holding out for? Why not add some moisture to your house to improve the happiness and health of both you and your plants?
Is a humidity of 50 favorable for plants?
The heat is always on because it’s the midst of winter and the daytime highs only reach the teens or single digits. As a result, my home’s air is dry, and several of my plants appear to be suffering as a result of the low humidity. I made the decision to conduct some study to determine the ideal humidity level for plants.
For the majority of mature plants, a humidity range of 50% to 60% is appropriate. Several tropical plants, including the pineapple,
Your desired humidity level will, of course, depend on the kind of plants you intend to grow. The stage of a plant’s development also affects the appropriate humidity level. Additionally, temperature and humidity interact, and you may occasionally choose to maximize one at the price of the other.

Can indoor plants tolerate high humidity levels?
But your regular indoor plants aren’t one of them. There are some plants that are native to hot tropical regions and prefer nothing more than air so dense with moisture that a normal person can hardly breathe. By stimulating the development of bacterial and fungal infections, which frequently require extremely high humidity to infect tissues, high indoor humidity levels pose substantial challenges for the majority of indoor plants.
In the same way, controlling humidity in greenhouses is essential to halting the spread of illness. The potential of spreading spores from sick plants to surrounding clean specimens is further increased by splashing water brought on by overnight condensation. Your greenhouse plants could be ravaged by active disease, undoing months or years of labor.
Is a humidity of 90% beneficial to plants?
Around the world, people use houseplants to brighten up indoor spaces, add color and texture, change the mood in a space (like an office), and for health benefits (air purification).
Because they are typically (but not always) tropical or semi-tropical plants, houseplants should be able to handle low light levels and somewhat high humidity levels. In our living spaces, particularly in the bathroom where the inherent humidity can harm other plants, high-humidity plants are fantastic.
Why Humidity Is Important to Plants
You can think of humidity as how much water the air can contain. The reason why extremely hot air has a “a humid feeling. Plants require humidity because the relative humidity within a plant is almost 100%. Plants’ leaves feature pores, which “breathing in carbon dioxide while exhaling water and oxygen. Considering how humid its interior is, plants are continuously losing water. The amount of water lost by a plant decreases with the relative humidity.
The Right Environment for Different Plants
Most plants need a humidity level of 60 percent or higher. Cacti and succulents are examples of desert plants that can withstand substantially lower humidity, often between 30 and 35 percent but occasionally as low as 20 percent. Higher humidity is needed for tropical plants, and natives of rain forests may require up to 90% humidity. The best place to keep these tropical plants is in terrariums, where the humidity can be more readily managed.
Do plants require moisture at night?
The semi-closed glasshouse takes a very different approach to daytime humidity than the traditional glasshouse. But how do the plants respond to the better airflow at night? The semi-closed glasshouse cultivation expert Godfrey Dol investigates it.
Even if heat is not needed to keep the plants warm, gardeners in a traditional glasshouse will turn on the heating system when the humidity deficit (HD) drops below 1.0-2.0 grams per cubic meter. Lower HD is produced as a result of heat movement and air warming. Through the vents, moisture is vented. This aids in the prevention of illnesses including botrytis and powdery mildew. In a semi-closed glasshouse, an HD of 0.2 to 0.5 is acceptable. The impact on energy use and heating costs is enormous.
Because heat moves air, typical glasshouse growers desire to employ the heating system to lower humidity. When compared to heating, the fans in a semi-closed glasshouse perform far better (and are less expensive).
If we consider the real reason why growers turn on the heating system when the humidity is above 85% (HD=1.3 at 18 degrees Celsius), we find that it is because the humidity measurement box is situated close to the top of the plant. In a traditional glasshouse, a humidity of 85% means that the humidity must be close to 100% in the lower part of the glasshouse, where there are many leaves and limited air circulation. The Botrytis and Powdery Mildew diseases are brought on by this dampness.
A more uniform climate is produced by the fans in a partially closed glasshouse. If there is an 85% humidity near the top, there will be an 85% humidity near the bottom. Dehumidification accounts for 20 to 30 percent of the fuel used in a typical glasshouse. This is greatly diminished in a glasshouse that is partially closed.
coolness and humidity at night What about nighttime cooling? Can we use the pad wall to cool down the 24-hour temperature at night on a warm night? Bringing moisture into a glasshouse at night seems counterproductive. This will undoubtedly promote Botrytis and Powdery Mildew. Godfrey wishes to provide an illustration.
The wet bulb temperature is 15.1 degrees if the ambient temperature is 20 degrees and there is a 60% humidity level. This means that simply turning on the pad wall, we can blow in air that is 15.1 degrees Celsius and 100% humid. The comparable humidity at 18 degrees Celsius in the glasshouse is 84 percent, which is more than suitable for nighttime humidity.
We can now see that there is no chance of condensation if the blow in temperature in the glasshouse is lower than the glasshouse air temperature, which eliminates the worry of introducing moisture into the glasshouse at night.
As a result, we can cool and humidify the air we blow in if we believe it will benefit the plant without worrying about increasing the risk of illness. This is especially important when the glasshouse needs to be kept cool at night to lower the 24-hour temperature while the daytime temperature is high.
When the nighttime humidity is less than 35 percent, it is not unusual to observe an interior temperature that is more than 10 degrees Celsius lower than the exterior temperature. More humidity is preferred by plants at night. At night, a relative humidity of less than 75% is not preferred.
weather at night Because, like a muscle, if you don’t utilize them, you lose them, plants will shed their roots during prolonged periods of dark weather. By installing a minimal pipe and opening the vents, growers in traditional glasshouses attempt to prevent this. When there isn’t enough sunlight, this will boost transpiration. Limiting root dieback will better prepare the plant for the inevitable arrival of the next sunny spell.
The activation in a semi-closed glasshouse is done by fans, who may produce much more transpiration by moving the air more swiftly. If the humidity is below 100%, the plant will still be stimulated by the air currents even if the glasshouse is in recirculation mode and there is no air exchange with the outside air. According to Godfrey, increasing the fan speed and attaining 5–6 air exchanges per hour is a great strategy to stop root die off and get your plants ready for the first sunny day.
Godfrey included a table with suggested humidity deficits in his previous post. He distinguished between an HD that affected the plant vegetatively and generatively. Why a high humidity has a generative effect on a plant has baffled several individuals. Godfrey suggests a previous post where this is discussed for them.
Godfrey will go through which diseases and pest pressures can be greatly minimized in a semi-closed glasshouse in his following post.
