Whether you are looking to grow plants for medical use, for their looks, or you love being green, you should consider getting a plant humidifier to allow your plants to grow up to their full potential.
You need to provide your plants with the right conditions. And apart from sunlight and nutrient water, moist conditions also play a significant role in better growth. Therefore, plant humidifiers are a must for maintaining proper atmospheric conditions to grow.
But which is the best plant humidifier as the market has so many of them on offer? To help you in making your decisions, we have developed this guide, so keep reading.
What Features to Look for When Buying a Plant Humidifier
Size of your grow room
You need to pick the right kind of plant humidifier according to the size of your grow room. For example, for a space that is under 300 square feet, you will need a humidifier for a small room. Anything between 350 and 550 square feet will require a medium-sized plant humidifier.
Whereas any room larger than 550 square feet will need a giant plant humidifier. The unit needs to keep the humidity levels over 60% in the entire room to boost plant growth. Don’t go for too much moisture in a small room, or you will damage your plants.
Type of the humidifier
It will help if you either go for an ultrasonic or evaporative cool mist plant humidifier. This unit needs to be portable and mobile. Ensure you don’t place your humidifier too close to the plants because it also releases heat that can influence the growth of your plants.
Therefore, you need to go for a portable cool mist plant humidifier that you can move easily. But keep in mind that cool mist units consume more energy as compared to warm mist units.
If you are sleeping close to your grow room, make sure the plant’s humidifier doesn’t make much noise. However, you will notice that even some of the best plant humidifiers do make some noise. Therefore, you will have to do a bit of research to find a low noise level device.
Water tank size
Consider the size of the water tank of your plant’s humidifier. The tank size should be large because the primary purpose is to provide your plants with moisture. With a larger tank, you won’t have to refill the unit too frequently.
Is a humidifier good for plants?
If the area in which you live has a tropical climate, you will notice a lot of humid air around there. This is an area where you don’t need to have a humidifier for your plants.
But in a dry and hot desert-like region, your plants will need some assistance. The point here is to provide your plants with a humid environment in which they can thrive.
Do all plants need a similar kind of humid environment?
No, not all plants need a similar kind of humid environment. Some need more humidity than others. For some of them, more humidity will do more harm than good. Therefore, your humidifier needs to provide your plants with the right kind of environment in which they grow and flourish.
