Alocasia Light Requirements
Alocasia needs 300–800 fc, classified as bright indirect light. Best window direction: East-facing (ideal); south with sheer curtain.
How low can it go?
Below 200 fc, Alocasia goes dormant (drops leaves) faster in winter. Variegated and silver-veined forms (Frydek, Polly) need higher light to maintain color.
Yellowing and dropping leaves, faded veining, premature dormancy.
How much is too much?
Tolerates morning direct sun. Afternoon direct sun burns the velvety leaf surface.
Brown patches on velvety surfaces, leaf curl, faded silver-and-green patterns.
The most common Alocasia light mistake
Owners assume Alocasia "went dormant and died" when it dropped all its leaves in winter. Dormancy is normal — reduce watering and wait for spring re-sprout.
Grow light substitute
A 20–30W full-spectrum LED 12 inches away helps prevent winter dormancy in mild climates. Pair with 60%+ humidity.

How to measure light at home
Download a free smartphone app like Light Meter or use a $20 digital light meter. Measure at the leaf surface, not the ceiling. As reference points: 50–100 fc is dim corner light; 100–400 fc is medium indirect; 400–1000 fc is bright indirect; 1000+ fc is direct sun.
