The light audit
This is the interactive version of what the lessons just walked through — made to keep open next to the plant. Nothing you type is saved or sent anywhere.
How much light is this spot, really?
Take a reading with a phone light-meter app (most read in lux) at midday, held facing the light where the plant sits. Type it in.
No light meter? Use the shadow test: at midday, hold a hand ~30 cm above the spot. Crisp shadow = high, soft = medium, faint = low.
