Controlling the humidity in a green room is very important to the health of the plants and vegetation that is being grown. While there is usually plenty of humidity to be found in a green room, or greenhouse, there are times when the humidity is too low for the plants to thrive. There must be a consistent humidity level of at least 50% to 75% in the green room for the plants to be able to stand tall, have great color, and last longer. Controlling humidity levels in the green room is not as difficult as one may think. And, it can be done without expensive appliances.

Step 1: Use Buckets of Water

During the course of the day, if you notice that the humidity levels in the green room are not where it should be, you can use a simple bucket with water. Depending on the severity of the dry spell, or low humidity levels, you can place a couple of buckets of water around the green room. The water will evaporate into the air as the heat builds inside the room, or greenhouse. It is important to keep the buckets full of fresh water and do not let them stay stagnant too long. This can lead to the growth of algae and mold.

Step 2: Use A Mister

A mister is a very easy to use tool. The mister can come in two different styles for automatic, or manual, operation. A spray bottle can be used as a misting device. You go around your green room and spray a fine mist throughout the room and on the plants. These small droplets will then evaporate, or be absorbed into the leaves. You can also place an automatic mister that will emit a fine mist periodically during the day.

Step 3: Place Humidifier in Green Room

Controlling humidity levels in a greenhouse, or a green room, is very easy with the use of a humidifier. You do not need to have a large humidifier, unless you have a large green room. A basic humidifier where you can set the level that you need keep will suffice. This will keep a flow of moist air flowing in the room so the plants will be able to get the moisture that they need.

Step 4: Use A Pebble Tray

Another method to controlling humidity in a green room is to use a pebble tray. This is a tray of small pebbles that is positioned under the plants. These trays are full of clean water. As the temperature rises, the water evaporates and rises to keep the plants moist.

Step 5: Place Wet Rags Near Windows

The green room should have plenty of windows to allow the sun's rays to heat up the room, and contribute to photosynthesis. Around the windows will be a great deal of heat. Place some wet rags, or sponges, around the windows to allow for the water to evaporate. As it evaporates it will increase the humidity levels in the room.

Step 6: Add Fans and Open Windows

If you find that there is too much humidity in the room, and the plants are showing negative signs, open up the windows and put in some fans. This will move the air and keep it flowing to decrease humidity.
