Why might you need a light meter app like GreenThumb?

It’s difficult to visually distinguish the difference between “bright" vs. partial sunlight. It's especially challenging on overcast days or if you’ve just moved from a dark room into a mildly-lit room. And how bright is “bright” anyways?

The GreenThumb app offers a tangible answer to a cloudy question—How much light is really in your home, greenhouse, or garden? It really takes the guesswork out of relying on our eyes to determine how much light is too much or not enough. The human eye isn't perfect after all! Different types of plants need different amounts of light intensity to thrive, and with MQ GreenThumb you'll know exactly which plants will thrive wherever you are.

Both functional and easy to use, MQ GreenThumb offers clear descriptions and pictures, as well as the associated light ranges required for each plant. The optimal light ranges are conveniently integrated with the light meter to help you find the best location to place every plant.

This is the ONLY plant-specific app available that uses your device camera as a light meter. Simply place your phone in the area where you wish to grow your plants and watch the light meter measure how much light there is. The app will show you an exact reading in your choice of foot-candles or lux, (which are light-measurement metrics). It will show you how much light is required for any specific plant, so you can rest assured put your green thumb to use! No longer will your cactus shrivel up in that dark corner of your house, because you’ll know, "BRIGHT" means it will need at least 3,000 foot-candles to grow and flourish!
