Anthurium Light Requirements
Anthurium needs 400–1000 fc, classified as bright indirect light. Best window direction: East-facing (ideal) or south with sheer curtain.
How low can it go?
Below 300 fc, the colorful spathes (flowers) stop forming entirely. The plant survives but never blooms.
No flowers; small, sparse leaves; long stretches between new leaves.
How much is too much?
Tolerates morning direct sun. Afternoon direct sun burns leaves and faded spathes.
Yellow patches on leaves, scorched spathes, leaf curl.
The most common Anthurium light mistake
Owners expect Anthurium to bloom in low light. Without bright indirect light, it produces only green leaves — the famous flowers require real light.
Grow light substitute
A 25W full-spectrum LED 12 inches away triggers reliable flowering. Many growers credit grow lights for year-round Anthurium blooms.

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.
