Color-Change Houseplant Water Meter

 PlantDoc® is a patent-pending, completely biodegradable & plastic-free color-changing moisture meter for plants. A fun and vivid visual guide to houseplant watering, PlantDoc® is perfect for new plant parents and anyone learning about how moisture affects their plants' health. PlantDoc® works by absorbing water from the soil just like plants do. When the soil is wet, PlantDoc absorbs the moisture and changes color from white to a green Rhaphidophora tetrasperma design. As the soil dries out, PlantDoc returns back to white from top to bottom. Unlike other stay-in moisture meters, PlantDoc® is affordable, completely biodegradable AND easy on the eyes!
