Building an outdoor plant box with a built-in chlorine gas detector is a practical and safety-conscious project for gardeners. Chlorine gas, often used in water treatment or pool maintenance, can harm plants if leaked. Here’s a step-by-step guide to creating this innovative planter.

Materials Needed:

- Wooden planks (cedar or redwood for durability)

- Screws, nails, and wood glue

- Chlorine gas detector (portable or fixed)

- Drill and saw

- Waterproof sealant

- Soil and plants

Step 1: Design the Plant Box

Sketch a simple rectangular or square design. Ensure it’s deep enough for plant roots (at least 12 inches). Add drainage holes at the bottom.

Step 2: Assemble the Frame

Cut the wooden planks to size and assemble the box using screws and wood glue. Reinforce the corners for stability.

Step 3: Install the Chlorine Gas Detector

Mount the detector inside the box, near the base where gas might accumulate. Ensure it’s waterproof and connected to a power source if needed.

Step 4: Seal and Protect

Apply waterproof sealant to the wood to prevent rot. Let it dry completely.

Step 5: Add Soil and Plants

Fill the box with quality soil and plant your chosen greenery. Position the box in a shaded area to protect the detector from direct sunlight.

Safety Tips:

- Test the detector regularly.

- Avoid placing the box near pools or chemical storage.

- Replace batteries or sensors as recommended.

This DIY project combines gardening with safety, ensuring your plants thrive in a healthy environment. Happy building!
