PlantDoc® is a patent-pending, completely biodegradable & plastic-free, color-changing moisture guide for plants.
It works by absorbing water from the soil just like plants do. When the soil is wet, PlantDoc absorbs the moisture and changes from white to green. As the soil dries out, PlantDoc gradually changes back to white. PlantDoc is an effective and attractive way to monitor houseplant watering for both novice and experienced plant owners. Unlike other moisture meters, PlantDoc is both budget-friendly and eco-friendly!
