Understanding Light Levels for Healthy Plant Growth

As soon as the illumination conditions are measured, it is time to match those results with what your garden truly needs.

Scan your plant via the Plant ID feature or find it manually using the Search tab to explore detailed care requirements, including preferred light levels. Finally, spot a location that provides just the right amount of sunshine or shade for healthy growth. That’s it.

What flower am I? The best one!

We love to travel a lot. Been to many countries and never knew what we saw. Luckily, I stumbled upon AI Plant Finder, and checked photos to find their names: black colour flowers, trees with pink flowers… Great job you’ve done!

Best Bing plant identifier!

My sweet cherry trees were suffering for a good half of the year. The app helped me find out what was going on and heal my little garden. A big thank you from me and my family! The best app

You saved my flowers!

My friend told me to use paprika for sick greens. What a surprise when I installed your app and found out it was harmful to my garden. Other plant disease identifiers didn’t warn me, but your app saved my flowers.

Next-gen botany app

I take more photos of leaves than selfies now. Not sure what that says about me. But this app made me fall in love with weeds. Yes – that’s cool.

AI IS the thing

Great for anxious plant parents. It doesn’t ID your plants, it GUIDES them. I truly appreciate your water demand calculator. Felt like a personal trainer but for greenery.

Frequently Asked Questions

  • Yes, it absolutely can! With the right app installed (a nod to AI Plant Finder) with a built-in lux meter, your smartphone may be a powerful tool to measure lux intensity around your greenery. No extra hardware needed.

  • Lux meters can be quite accurate. Our free light meter app for plants uses your phone’s sensors to provide reliable estimations and help you choose the best conditions for your leafy friends.

  • Certainly! iPhones are equipped with sensors that, through apps like AI Plant Finder, can measure brightness levels effectively.

  • Yes. Most modern smartphones can measure lux intensity using their built-in sensors, but via dedicated apps.

  • It depends on the species. Some need bright, direct light (e.g., succulents), while others thrive in low light (e.g., peace lily). Use the best free light meter app to match the species’ preferences with your environment.

  • Any, when inappropriate. Too much direct sunlight can cause leaf burn, dehydration, or bleaching. UV-heavy or very intense artificial lights can also be harmful. Preliminary estimates matter.

  • Not for long. Light is essential for photosynthesis. While some tolerate low light, all species still need at least some level to survive.

  • These are pothos, philodendron, peace lilies, etc. They are perfect for shady corners or spaces without direct sun.

  • Yes, you can. Indeed, specialized grow lights are ideal, yet many LED tools can support growth. Ensure the intensity and duration that suit your plant’s needs.

  • Sometimes, yet not always. Standard indoor illumination may help low-light plants survive, but it typically lacks the intensity for optimal growth.

  • A lot. Indirect illumination can be the difference between thriving and surviving. It means the plant receives bright ambient light without being scorched by direct sunbeams. This is perfect for many popular species held at home, e.g., ferns, calatheas, and peace lilies.
