How much light does an orchid need?
An orchid does best in bright indirect light. It will survive in medium, and on direct sun: east window ideal; no hot direct sun.
| Ideal | bright indirect |

What those words actually mean in a room
"Bright indirect" is the most misused phrase in houseplant care, so here is the plain version. The test that matters is not how bright the room feels — your eyes adjust and a plant's leaves do not — it is how much sky the plant can see from where it sits.
- Bright indirect — a big, unobstructed view of sky, without the sun's disc landing on the leaves for long. Right beside an east or north window, or set back a few feet from a south or west one.
- Medium indirect — a partial view of sky: a few feet into the room, or beside a window with a tree or building in the way.
- Low — survivable, not good. Well back from the only window, or in a room whose window faces a wall. Most "low light" plants merely tolerate it; almost none prefer it.
- Direct sun — the sun's disc visibly on the leaves. A few species want this; for most it scorches, and the ones that take it need acclimatising to it gradually rather than being moved straight out.
Reading the plant instead
Silvery-green roots are thirsty; plump green roots are hydrated. Read the roots, not a calendar.
Light also decides how often this plant drinks — the same orchid in brighter light dries out faster and wants water sooner. If you are moving it, expect the watering interval to move with it: how often to water an orchid.
Plantroster tracks what each of your pots actually does — season, the forecast where you live, and whether the soil was still damp last time you checked — and tells you when to check this one, not when to water it.
