How can I effectively use a tray for plants to improve the health and growth of my indoor garden?

Using a tray for plants can help improve the health and growth of your indoor garden by providing a stable and controlled environment for your plants. Place the tray under your pots to catch excess water and prevent water damage to your floors. This helps maintain proper moisture levels for your plants and prevents root rot. Additionally, you can add pebbles or water to the tray to create humidity, which can benefit certain plants. Make sure to empty the tray regularly to prevent mold and pests.
