Ideal temperature for pak choi 'dwarf white stem'
Pak Choi 'Dwarf White Stem' is comfortable in any room a person is comfortable in, roughly 13-21°C (55-70°F). The mistakes are micro-climates: a north-facing window on a frosty night, a south-facing windowsill in a summer heatwave, the standing draught between an opened kitchen door and the radiator behind it. Read the room around the plant, not the thermostat. Below roughly 13°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Pak Choi 'Dwarf White Stem' is comparatively hardy (USDA Grown as a cool-season annual; tolerates light frost, best in spring and autumn, RHS H3 (half-hardy; tolerates light frost but not hard freezes)). Within that range it tolerates a cold dormant spell outdoors; outside it, grow it in a container you can move under cover or overwinter in a cool but frost-free spot. Hardiness assumes an established plant in well-drained soil — a wet, cold root zone kills far more plants than cold air alone.
Humidity for pak choi 'dwarf white stem'
Pak Choi 'Dwarf White Stem' sits happiest at around 40-70% relative humidity. An open-ground or cool-tunnel crop with no special air-humidity needs; consistent soil moisture matters most. 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.
