Slipper Orchid prefers low to medium but will cope with low to medium. Harsh midday sun can scorch sensitive leaves, while too little light leads to leggy, sparse growth.
Keep Slipper Orchid between 16–28 °C and aim for around 60% humidity (45% minimum). Below 12 °C it risks cold damage — keep it away from draughty windows and radiators.
