How humidity affects your houseplants

Healthy plants thrive in environments where humidity levels are optimal. Too much or too little moisture can spell disaster for your leafy mate. Tolerance levels for humidity differ per plant type, but here’s a general guideline on how the wrong level of humidity can affect your plant’s health. 


Excess humidity can lead to mould growth and root rot, while insufficient humidity can cause wilting and dehydration. By using a humidity meter for plants like our Sensor, you can ensure that your plants are always right in their comfy zone.
