Humidity is an important condition that is needed by plants in an indoor garden. The need for this humidity is higher in winter than in any other season because during winter the air is completely dry. Nonetheless, at this season, we have the heating on and the windows of our home shut; therefore, no moisture content in the air.

Indoor plants require a certain amount of moisture content in the air for them to have healthy growth. Nevertheless, moderate humidity levels are much more comfortable for you than low humidity, particularly when working in the indoor garden. There are options you can use to increase humidity for your indoor garden. These options include:
1. Group your plants
Transpiration is a process where plants lose water from their leaves via the stomata. The water lost is in the form of water vapor, and it enters the air around the plant. Through this, the immediate vicinity or air around the plant will have high moisture content (humidity). Therefore, by grouping your indoor plants, you'll be increasing the amount of transpiration, and in turn, the humidity levels will go up.
2. Mist your houseplants
The first option indoor farmers will think of when it comes to increasing humidity is to mist their plants. This can be achieved by using a simple spray bottle, which allows them to spray the air (with high moisture content) around their indoor garden as well as directly onto the plants. It is a quick and easy method; however, it provides an increase in humidity level for a short time. Therefore, it is essential to repeat the process as needed.
3. Use a humidifier and dehumidifier
The ultimate flawless option to humidify your indoor garden is using a humidifier. All you need to do is to turn it on to increase the humidity and turn it off when the desired humidity level is achieved. For you to achieve the perfect balance of humidity, it is essential to use humidifiers and dehumidifiers for indoor gardens. It’s because as the humidifier increases, the dehumidifier reduces; therefore, no chance of your indoor garden getting too dry or too dump.
4. Use a pebble tray
It is a simple way to increase humidity in your indoor garden. You can use the pebble tray on one plant or several plants. What you'll need here is a drip tray whose diameter is twice the diameter of the plant's pot base. Nonetheless, it should be an inch deep to ensure that the evaporation of water inside is moderate. Add some pebbles that almost have the same size of the base of the tray, then add water. Ensure the water level is not above the top of the pebbles. Take your indoor plant pot and place it on top of the pebbles, without the base of the pot being submerged in water. The evaporation of the water will be slow; hence, increase the humidity.
5. Use a terrarium
You can get either an open or closed terrarium that helps to provide very high humidity or moderate humidity levels within the terrarium respective micro-climates. If you are in a dry and cold region, use the closed terrariums as they provide high humidity levels. The open terrariums have a massive opening to allow air from outside to get in and circulate freely inside the terrarium. The glass walls in the open terrariums trap a fair amount of moisture content in the air; hence, reduce ventilation and increase humidity levels.
The ideal humidity level for indoor plants is between 50% and 60%. With these ways, you can achieve these humidity levels easily, and most of your plants will flourish and remain healthy.
