Building an outdoor plant box with a humidity dome is a fantastic way to create an ideal environment for seedlings and young plants. Here’s a step-by-step guide to help you craft your own.

Materials Needed:

- Wooden planks (cedar or treated pine recommended)

- Clear plastic sheeting or a polycarbonate panel

- Hinges and screws

- Drill and saw

- Measuring tape and pencil

- Waterproof sealant

Step 1: Construct the Plant Box

Cut the wooden planks to your desired size (e.g., 24"x12"x8"). Assemble the box by screwing the sides together, ensuring sturdy corners. Apply waterproof sealant to protect the wood from moisture.

Step 2: Create the Humidity Dome

Cut a piece of clear plastic or polycarbonate to fit the top of the box. Attach it to one side using hinges, allowing easy access. Ensure the dome is tall enough to accommodate plant growth.

Step 3: Ventilation and Maintenance

Drill small holes in the dome for airflow, preventing mold. Monitor humidity levels and mist plants as needed. Open the dome occasionally to regulate temperature.

Benefits:

- Protects seedlings from harsh weather

- Maintains consistent humidity for faster growth

- Reusable and customizable for various plants

With this DIY project, you’ll enjoy healthier plants and a thriving garden!
