Building an outdoor plant box with an EC (Electrical Conductivity) meter is a fantastic way to monitor soil health and ensure optimal plant growth. Here’s a step-by-step guide to help you create your own.

Materials Needed:

- Wooden planks or cedar boards (weather-resistant)

- Screws and a drill

- Saw

- EC meter (with probes)

- Waterproof sealant

- Potting soil and compost

Step 1: Design Your Plant Box

Decide on the size and shape of your plant box. A rectangular design (e.g., 4ft x 2ft x 1ft) works well for most gardens. Cut the wooden planks to size and assemble the frame using screws.

Step 2: Install the EC Meter

Drill a small hole near the base of one side to insert the EC meter’s probes. Ensure the probes reach deep into the soil for accurate readings. Seal the hole with waterproof sealant to prevent moisture damage.

Step 3: Add Soil and Plants

Fill the box with a mix of potting soil and compost. Plant your chosen greens, leaving enough space for growth. Water thoroughly and let the soil settle.

Step 4: Monitor and Adjust

Use the EC meter to check soil conductivity regularly. High readings may indicate excess salts; low readings suggest nutrient deficiency. Adjust watering or fertilization as needed.

This DIY project combines practicality with smart gardening, helping you grow healthier plants with precision. Happy building!
