Building an outdoor plant box with a temperature gauge is a fantastic DIY project for gardeners who want to monitor their plants' environment. Here’s a simple guide to help you create one:

Materials Needed:

- Wooden planks (cedar or redwood for durability)

- Screws and a drill

- Waterproof sealant

- Soil and plants

- Digital temperature gauge (weatherproof)

- Basic tools (saw, measuring tape, sandpaper)

Step-by-Step Instructions:

1. Measure and Cut the Wood: Decide the size of your plant box and cut the wooden planks accordingly. A standard size is 24x12x12 inches.

2. Assemble the Box: Use screws to attach the sides, bottom, and front/back panels. Ensure the structure is sturdy.

3. Apply Sealant: Coat the wood with a waterproof sealant to protect it from moisture and extend its lifespan.

4. Install the Temperature Gauge: Drill a small hole near the top edge of the box to place the temperature sensor. Secure it firmly.

5. Add Soil and Plants: Fill the box with nutrient-rich soil and plant your favorite flowers or herbs.

6. Monitor Temperature: Check the gauge regularly to ensure optimal growing conditions for your plants.

Tips:

- Place the plant box in a spot with adequate sunlight.

- Choose a gauge with a clear display for easy reading.

- Adjust watering based on temperature readings to prevent over/under-watering.

This DIY project combines functionality and aesthetics, making it a great addition to any garden. Happy building!
