However, this model does not support the use of essential oils, which might be a drawback for users looking to use it for aromatherapy. The unit is also lightweight and compact, making it easy to place within a grow tent without taking up much space. Despite its strengths, some users might find the delay in the auto shut-off function a concern, although it’s generally seen as a minor issue.
