How It Works
GROW ROCK updated the old copper method with today’s technology to generate harmless microcurrents around plant roots. This increases absorption of water and nutrients, which results in dramatic growth and improved yield WITHOUT chemicals or fertilizers.
ELECTROCULTURE has been used for hundreds of years. Its benefits have been documented in St Petersburgh in 1900; by Britian in 1845 and 1918; by the USDA in 1964, 1985, and 1994; by China in 2018 and 2022; and by decades of school children all over the world in science fairs and classrooms.

How To Use
GROW ROCK is simple to use. Set the two prongs into the soil and face the solar panel toward the sun. It works automatically. Water as needed. GROW ROCK increases root absorption, so monitor plant moisture carefully. Enjoy your plant’s increased growth.
GROW ROCK is safe to use around children and pets. Perfect for anywhere in your home. Plus, it is powered by the sun, so it is eco-friendly and requires no batteries.
Test Indicator
You can TEST your GROW ROCK by temporarily moving the solar cell to bright sunlight and watching the little leaves in the indicator window dance, and tap, in happiness and delight.
Test mode requires bright light; however, your individual plant may require lower lighting for optimal growth. Therefore, always return your plant to its preferred lighting after performing the test. Your plant will still get the benefits of GROW ROCK even in light conditions too low for the indicator.
Disable Indicator
To disable the indicator, push the red button firmly into the GROW ROCK until it is flush with the bottom and movement stops. Note: This is not reversible.
