# Best Humidity Trays for Bonsai Source: https://bonsainest.com/best/best-humidity-trays Updated: 2026-10-02 Publisher: Bonsai Nest. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://bonsainest.com/how-we-research#our-score Humidity trays raise moisture in the small pocket of air directly around a tree, which matters most for tropicals in heated rooms through winter. They are not a substitute for a bright window or correct watering, and the effect drops off quickly as you move away from the pot. What varies is surface area, tray depth, whether pebbles are included, and whether the pot sits above the waterline or ends up standing in it. We weighed footprint and depth, since a wide tray holds far more evaporating surface than a deep narrow one. Pebble trays suit ficus, fukien tea and other tropicals on a windowsill. Larger flat trays suit growers with several small trees grouped together. Metal and slate trays suit anyone who wants the tray to disappear visually. Keep the pot base above standing water, or you trade humidity for waterlogged roots. ## Picks ### 1.
