One of your plants may suffer from low humidity at some point. A humidity dome is a perfect solution if you want to boost your plant’s humidity without using a humidifier or pebble tray.

Why does a plant need humidity?

Stomata are basically pores that control gas exchange in plants. Carbon dioxide, a gas, is essential to photosynthesis, and stomata facilitate the exchange of carbon dioxide. Photosynthesis is made possible by humidity, which keeps the stomata open. A plant’s stomata will close if it loses too much water, halting photosynthesis. The plant cannot survive without photosynthesis.

Signs that your plant needs more humidity:

  • The plant begins to droop and wilt
  • with yellow leaves
  • with brown edges
  • that turn crisp when touched

Conventional Ways to Increase Humidity for Plants

You can increase humidity around your plants in a few conventional ways. These methods, however, have some negative effects.

A humidifier, for example, can increase humidity for you and your plants. Mold can, however, grow on your walls if there is too much moisture in the air. Furthermore, using the wrong kind of water in your humidifier can introduce bacteria into the air, which can harm you and your family.

You can keep your plant’s stomata open by misting the leaves. A constant misting of your plants’ leaves, however, can eventually lead to fungal growth.

You can mist the leaves of your plant by placing it on top of a pebble tray filled with water. The water in a pebble tray evaporates into the room, so it cannot really control humidity.

The Benefits of a Humidity Dome

Adding more humidity to your plants is easy with a humidity dome. When the humidity is optimal, the result is a healthier, lusher, and more beautiful plant.

A humidity dome is also easier to use. A humidifier, for instance, won’t need to be cleaned. Also, you won’t have to mist your leaves constantly. The humidity dome creates a micro-environment for your plant, so it won’t be lost to a large room.

How to Make a Large Humidity Dome

Several simple supplies can easily be found at most stores like Walmart or Target, or online at Amazon.

Here’s what you’ll need:

Instructions:

You should first remove the lid from the storage bin and place it upside down on the surface where you will be keeping your plant. Choose an area that receives indirect, bright sunlight.

Next, place your plant on top of the lid.

Fill your cups, bowls, or shallow tray with water and place them on the lid alongside your plant.

Spray some water on the lid of your spray bottle. Water droplets on the large surface of the lid have a larger surface area, so they will help to increase the humidity in your dome more rapidly.

Your humidity monitor should be placed on the lid by your plant. By doing so, you can monitor the humidity inside the dome. You can keep your humidity monitor dry by putting it on top of an upside-down container.

Last but not least, cover the plant, water vessel, and monitor with the storage bin to create your micro-environment!

Things To Consider with a Humidity Dome

You should not keep your plant inside a humidity dome for a long period of time because plants need lots of air to grow properly. You should remove your plant from the humidity dome once it shows signs of recovery.

Alternatively, you can vent your humidity dome for a few hours each day. You can also drill holes on the side of the storage bin to vent your dome and to allow air inside.

Humidity Dome Uses

Your humidity dome will provide your plant with up to 90% humidity. If your plant needs some extra moisture, give this a try and prepare yourself for the amazing results.

This humidity dome can be used to rehabilitate many plants, even dying ones. With such an economical way to make a humidity dome, it’s worth a shot to see if you can save some of your less healthy plants.

For a humidity dome that looks nice (for lack of a better word), you can use a glass cloche or small greenhouse. The cost-effective option may be to use a large plastic storage container since it is rather difficult to find large humidity domes made of glass. You may not mind the look of some storage bins since they’re quite neutral in style. Ultimately, it is all about the health of your plants.
