A pilea, the Chinese money plant, gets 100 out of 100 on an east sill, where we estimate 6,500 lux on a clear day. Carried back into the room it holds 99 or 100 for two and a half metres, then drops to 69 at three. On the sill, what moves the score is the room’s temperature, and this plant likes it cool: a great fit from 17 to 26 °C, and 68 at 16.
Read on 14 October 2026, the answer box at the top of Google’s results calls east one of the best spots for a pilea, for its gentle, cool morning sun, and adds a warning about cold drafts. The pages under it barely argue. The RHS puts a pilea near a north, east or west window, and pilea.com prefers north or east because too much sun can stress the leaves. A reply on the National Gardening Association forum wants the pot as close to the glass as it goes, with two or three hours of direct sun at most. JOMO Studio lists a few metres back from a large east window as its lowest-light option.

Is morning sun too much for a pilea?
Here are the light figures other sites publish for this plant, before any of ours:
| Who publishes it | What it says a pilea needs | What the figure is |
|---|---|---|
| getgrowli.app | 4,000–8,000 lux | Its "Bright Indirect" tier, a band the site prints for several other plants as well |
| getgrowli.app | 400–800 fc | The same tier, given in foot-candles |
| foliage-factory.com | approx. 10,000–20,000 lux | "Bright indirect" on a shop's product page for this plant |
| scienceinsights.org | 10,000 and 20,000 lux | The range it says bright indirect light typically falls between, in an article on pilea light (10 November 2025) |
| bloomingexpert.com | 1,000 to 2,000 foot-candles | Stated as what a pilea needs |
| bloomingexpert.com | roughly 1,000 foot-candles | A grow-light target, run 12 to 14 hours a day |
Taken as targets, two of these would rule out the whole of an east room. Foliage Factory and Science Insights both put the figure at 10,000 to 20,000 lux, and our estimate for the east sill is 6,500. Growli’s 4,000 to 8,000 band would end short of the 1.5 m row in the table further down. Yet the care pages in those results all put east among the good windows for this plant, and our scoring sides with the care pages.
The sill’s light reads as ideal for a pilea. We dated it to midsummer and to midwinter, at latitudes from 10 to 60 degrees, and an east sill never once scored as too bright. South glass is where the light does get flagged, on the sill and half a metre in; a metre back, the flag is gone. So pilea.com’s worry about too much sun holds for a window it already steers you away from. Hours of direct sun aren’t an input, which leaves the forum’s two-or-three-hour cap untested either way.
How far from an east window can a pilea sit?
Two and a half metres before anything changes. One pilea, moved back from the glass:
| Distance from the glass | Estimated light | What the light is doing | Verdict |
|---|---|---|---|
| 0.3 m, against the glass | 6,500 lux | Just the right amount of light | Great fit, 100/100 |
| 1 m back | 5,000 lux | Just the right amount of light | Great fit, 100/100 |
| 1.5 m back | 3,969 lux | Just the right amount of light | Great fit, 100/100 |
| 2 m back | 3,150 lux | Just the right amount of light | Great fit, 99/100 |
| 2.5 m back | 2,500 lux | Just the right amount of light | Great fit, 99/100 |
| 3 m back | 1,984 lux | A little dim, but workable | Worth a try, 69/100 |
| 4 m back | 1,250 lux | A little dim, but workable | Worth a try, 65/100 |
For two and a half metres nothing happens, and then the light crosses the bottom of the pilea’s band: 2,500 lux scores 99, 1,984 scores 69. That’s thirty points lost in half a metre, and the next whole metre costs only four more. A shelf two metres in scores 99, one point under the sill, so pressing the pot against the glass buys almost nothing. JOMO’s lowest-light spot lands right on the edge: still a great fit at two and a half metres, only workable at three.
That edge belongs to the window more than to the plant. A moth orchid at the same glass loses its top band over the same half metre, because the two plants’ light bands bottom out at about the same level.
None of these lux figures came off a meter. We work them out from which way the window faces and how far back the pot stands, for a clear day. Anything outside that shades the glass pulls every row down, and the step moves toward the window with it.
How cold can the room get for a pilea?
Colder than for a monstera. Here is the sill from the card again, at seven room temperatures:
| Air temperature at the sill | What the light is doing | What the warmth is doing | Verdict |
|---|---|---|---|
| 12 °C | Just the right amount of light | Too cold here | Not the best fit right now, 48/100 |
| 13 °C | Just the right amount of light | A little cool, but workable | Worth a try, 64/100 |
| 16 °C | Just the right amount of light | A little cool, but workable | Worth a try, 68/100 |
| 17 °C | Just the right amount of light | Comfortable temperature | Great fit, 99/100 |
| 22 °C | Just the right amount of light | Comfortable temperature | Great fit, 100/100 |
| 26 °C | Just the right amount of light | Comfortable temperature | Great fit, 99/100 |
| 27 °C | Just the right amount of light | A little warm, but workable | Worth a try, 67/100 |
The light column reads the same on every row. The verdict keeps a great fit from 17 to 26 °C and loses over thirty points one degree past either end: 68 at 16, 67 at 27. Below 16 there’s a workable shelf, still 64 at 13 °C. Only at 12 does the warmth column switch to too cold, and the score to 48.
That band sits about three degrees below a monstera’s. A house kept at 18 °C through the winter is inside it, while a monstera at this same window is already out of its top band at that temperature. The price comes at the warm end, the step at 27 °C that a pilea in a west window meets on summer afternoons.
The answer box calls the morning sun gentle and cool, and cool is the word doing the work. An east sill takes its direct sun early, on a room that cooled overnight, and is in shade by the warm part of the day. For a plant whose band tops out at 26 °C, that timing matters more than how strong the light is.
Where should a pilea sit in an east room in winter?
Nearer the glass, though not by much. Dated 21 December at latitude 40, the sill, one metre and a metre and a half all still score a great fit. Two metres and two and a half slip to worth a try. By late March both are back, so for the dark weeks the good strip is about a metre shorter.
Coming forward brings the pot toward the coldest air in the room, and for a pilea that’s less of a trade than it sounds. A sill that sits at 14 or 15 °C before the heating comes on costs it the top band but leaves it on the workable shelf; the table says the line that matters is 13. That’s the answer box’s warning about cold drafts with a threshold attached. The guide to minimum temperatures sets eight other houseplants’ ranges side by side and explains why published cold limits disagree so widely.
Why does a pilea lean toward an east window?
Because the light comes from one side and falls off quickly: 6,500 lux at the glass, 3,150 two metres in. The guide to leaning plants uses a pilea as its worked example. The answer box’s weekly quarter-turn evens out the shape but adds no light, so it’s worth doing once the spot itself is right.
The east window guide shows how quickly this window’s light runs out for other plants. For your own sill, with its own blinds and its own weather, the free spot checker runs the same scoring on the real thing.
