Building an outdoor plant box with a TDS (Total Dissolved Solids) meter is a fantastic way to monitor soil health and ensure your plants thrive. Here’s a step-by-step guide to creating your own DIY plant box with this handy feature.

Materials Needed:

- Wooden planks (cedar or treated pine recommended)

- Screws and nails

- Drill and saw

- Waterproof sealant

- TDS meter (with probes)

- Soil and plants of your choice

Step 1: Design and Cut the Wood

Start by designing the dimensions of your plant box. Cut the wooden planks to size for the base, sides, and ends. A typical size is 24x12x12 inches, but adjust based on your space.

Step 2: Assemble the Box

Use screws to attach the sides to the base, ensuring sturdy corners. Pre-drill holes to prevent splitting. Apply waterproof sealant to protect the wood from moisture.

Step 3: Install the TDS Meter

Drill a small hole near the base of one side to thread the TDS meter probes into the soil. Secure the meter’s display unit on the outside for easy reading. Calibrate the meter according to the manufacturer’s instructions.

Step 4: Add Soil and Plants

Fill the box with nutrient-rich soil, leaving space for plant roots. Plant your chosen greenery and water lightly. The TDS meter will now help you monitor soil nutrient levels, ensuring optimal plant health.

Maintenance Tips:

- Regularly check the TDS readings and adjust watering or fertilizing as needed.

- Clean the meter probes to ensure accurate measurements.

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

With this DIY project, you’ll have a functional and stylish outdoor plant box that keeps your plants healthy and thriving!
