Ideal temperature for pilea 'moon valley' (friendship plant)
Pilea 'Moon Valley' (Friendship Plant) is comfortable in any room a person is comfortable in, roughly 18-27C (65-80F).

Read the room around the plant, not the thermostat. Below roughly 18°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Pilea 'Moon Valley' (Friendship Plant) is frost-tender (USDA USDA zones 11-12 outdoors; grown as a houseplant elsewhere, RHS undefined). It cannot survive a frost, so in most of the US and UK it lives indoors year-round or summers outside and comes back in well before the first autumn frost — once nights drop toward 10-12°C is the cue, not the first frost warning. Acclimate it over a week when moving between indoors and out so the leaves do not shock.
Humidity for pilea 'moon valley' (friendship plant)
Pilea 'Moon Valley' (Friendship Plant) sits happiest at around 50-80% relative humidity. A tropical understory plant that loves high humidity. It stays happy around 50% but appreciates more. Boost humidity with a pebble tray, a nearby humidifier, or grouping plants. Low humidity causes brown, crispy leaf tips. The usual low-humidity tell is crisp brown leaf tips and edges while the soil moisture is fine — a sign the air, not the watering, is the problem. If you need to raise it, the reliable methods are grouping plants together, standing the pot on a tray of damp pebbles (the pot above the waterline, never in it), or running a small humidifier in winter when indoor heating dries the air most. Misting is the least effective — it raises humidity for minutes, not hours.
