Building an outdoor plant box with a built-in oxygen meter is a fantastic way to ensure your plants thrive in optimal conditions. This DIY project combines gardening with technology, allowing you to monitor oxygen levels in the soil for healthier plants. Here’s a step-by-step guide to help you create your own.

Materials Needed:

- Wooden planks (cedar or redwood for durability)

- Screws and a drill

- Soil oxygen meter (available at gardening stores)

- Waterproof sealant

- Measuring tape and saw

- Potting soil and plants of your choice

Step 1: Design Your Plant Box

Decide on the size and shape of your plant box. A rectangular design is easiest for beginners. Cut the wooden planks to your desired dimensions using a saw.

Step 2: Assemble the Frame

Use screws to attach the planks together, forming the base and sides of the box. Ensure the corners are sturdy and the box is level.

Step 3: Install the Oxygen Meter

Drill a small hole near the base of one side to insert the oxygen meter probe. Secure it in place and ensure it’s easily accessible for readings.

Step 4: Seal and Protect

Apply a waterproof sealant to the interior and exterior of the box to prevent rot. Let it dry completely before adding soil.

Step 5: Add Soil and Plants

Fill the box with high-quality potting soil and plant your chosen greenery. The oxygen meter will help you monitor soil conditions, ensuring your plants get the right amount of oxygen.

Maintenance Tips:

- Check the oxygen meter weekly and adjust watering as needed.

- Reapply sealant annually to prolong the box’s lifespan.

This project is perfect for gardening enthusiasts looking to blend practicality with innovation. Enjoy your new outdoor plant box with a built-in oxygen meter!
