Do citrus actually benefit from humidity?  I thought I read they grow fine at 0% RH (ex. Arizona) as long as they are properly watered.

From the Internet:  Citrus like 50% humidity: Citrus needs humidity indoors. Provide increased humidity by standing potted citrus plants on trays of damp pebbles or moist peat moss. The humidity necessary to keep a citrus plant in good health is above 50% and pebble trays are a good way to localize that humidity.  I grow my trees in a greenhouse so they always are in high humidity.
