Alocasias need bright, but indirect light. This is due to the plant's natural habitat, on the forest floor beneath the tree canopy. Direct sun will cause the leaves to burn, so avoid placing your Alocasia in a spot where it'll be exposed to direct sun for a prolonged period.
Watering: Alocasia Cucullata prefers soil on the dry side but needs humidity in order to be happy. Mist the leaves occasionally. Placing a pebble tray nearby is a good way to increase the humidity around the plant consistently, and frequent misting is encouraged too.
