Various "ideal" humidity conditions may be required at different stages of a plant's life cycle. During germination and propagation phases, a relative humidity of 70% to 80% is generally preferred to promote root development. During the growth phase, the humidity level typically ranges from 50% to 80%. In the flowering stage, this level may drop to 40% to 60%. Temperature control is usually maintained between 21°C and 26°C, but the actual needs may vary depending on the plant species.
