SunCalc Shade Calculator

That's different.

From the website:

SunCalc®

When the tag says "Partial Sun," how do you know where to locate the plant for maximum growth?

SunCalc helps you find just the right spots where expensive shrubs and plants will thrive.

Place it where you're thinking of planting, set it, and 12 hours later you'll have a 100% accurate reading you can match to the nursery tags — Full Sun, Partial Sun, Partial Shade, Full Shade.

Then plant and enjoy!

Battery included.
