Optimize plant growth

Korona allows you to easily determine the relevant lighting conditions for your plants at the palm of your hand.

Always at your fingertips.

The App

Built for grow lights.

Korona is the light meter specifically built for grow lights. Measure Lux, PPFD and even calculate your plant’s DLI.


No equipment necessary.

Korona works by using your phone’s front-facing camera and advanced image processing algorithms to sense the light as your plant sees it.


Continously getting even better.
