9GreenBox Bonsai Humidity Drip Tray with Pebbles Rocks, 8-Inch x 6-Inch

Most homes are dry; with air conditioning and central heating pulling moisture needed by plants out of the air. Here's a simple solution: place bonsai on a low tray with a layer of decorative rock. Then water your bonsai from above. Excess water collects in the tray and slowly evaporates; increasing the humidity around the tree and improving the growing environment. Your bonsai tree thrives while windowsills stay dry and debris-free. A tray can also be used outdoors to improve conditions in dry or windy sites. Tray comes with decorative rocks.
