Spider Plant Light Requirements
Spider Plant needs 200–800 fc, classified as medium light. Best window direction: East or north (ideal); south or west with sheer curtain.
How low can it go?
Tolerates 100 fc but stops producing the iconic baby plantlets (spiderettes) on runners. Variegated forms revert to all-green.
No baby plantlets produced; variegation fades; growth slows dramatically.
How much is too much?
Tolerates bright indirect; direct afternoon sun scorches leaves and produces brown tips.
Brown crispy leaf tips (also caused by fluoride in tap water, so watch both); pale washed-out coloring.
The most common Spider Plant light mistake
Owners attribute brown leaf tips to under-watering when the actual cause is direct afternoon sun or fluoride in tap water.
Grow light substitute
A 15–20W full-spectrum LED 12 inches away works well. Spider plants respond fast to better light by producing more babies.

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.
