Measuring

Measuring Light

Simple methods: sunlight hours, phone light meter apps, and shadow tests.

Shadow Test
Shadow Test

Hold your hand 12" above a surface at noon. Sharp shadow = direct sun; soft shadow = bright indirect; no shadow = low light.

Light Meter Apps
Light Meter Apps

Use free apps to measure foot-candles (fc): 100-500 fc = low light; 500-1000 fc = medium; 1000+ fc = bright.

Count Sunlight Hours
Count Sunlight Hours

Track how many hours direct sun hits the spot. 6+ hours = high light; 2-4 hours = medium; <2 hours = low.

Sun Damage & Acclimation

How to identify leaf burn and how to acclimate plants safely.

Signs of Too Much Light:

Bleached or faded leaf color
Brown, crispy patches on leaves
