Ideal temperature for pilea glauca 'aquamarine' (grey baby tears)
Aim for 18-26C (65-80F) on the thermostat and you've handled the easy part. The hard part is the half-metre around the plant: window glass that drops to near-freezing on a January night, a radiator pumping out hot dry air, a draught from an opened front door. Move the plant 30 cm and you've usually fixed the problem. Below roughly 18°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Pilea glauca 'Aquamarine' (Grey Baby Tears) is frost-tender (USDA 10-12 (a tender tropical grown as a houseplant in cooler climates; not frost-hardy), 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 glauca 'aquamarine' (grey baby tears)
Pilea glauca 'Aquamarine' (Grey Baby Tears) sits happiest at around 50-60%+ (tolerates average household) relative humidity. As a forest-floor tropical it loves moderate to high humidity and is outstanding in terrariums and closed cases. It copes with normal room humidity, but dry winter air causes crispy edges and leaf drop. Group with other plants, use a pebble tray or run a humidifier to keep foliage lush. 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.
