PlantDoc water meter cards

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.

These cards are biodegradable and include 5 per pack.
