Decoding Light Labels for Houseplants

Direct/Full/Bright sun: Within 2 ft of unobstructed south/SE/SW window, 4–6 hrs direct rays.
Indirect/Filtered: 4 ft from same window, or behind sheers.
Low light: Near east/west window, couple hours direct.
Shadow test: On a sunny day, if your hand casts no sharp shadow, no plant will grow there.
Plants survive in less light but grow poorly and succumb easily to watering errors.
