Building an outdoor plant box with a built-in nutrient doser is a fantastic way to automate your gardening and ensure your plants thrive. Here’s a step-by-step guide to help you create this innovative planter.

Materials Needed:

- Wooden planks (cedar or redwood for durability)

- Waterproof lining or sealant

- PVC pipes or tubing

- Small water pump (submersible)

- Nutrient reservoir (a small container)

- Timer or smart controller

- Drill, screws, and basic woodworking tools

Step 1: Construct the Plant Box

Start by building a rectangular wooden box to your desired size. Ensure the wood is treated or sealed to withstand outdoor conditions. Add a waterproof lining to prevent rot.

Step 2: Install the Nutrient Dosing System

Drill small holes in the base of the box for drainage. Attach PVC pipes or tubing to distribute water and nutrients evenly. Connect the tubing to a small submersible pump placed in the nutrient reservoir.

Step 3: Set Up the Automation

Use a timer or smart controller to regulate the pump. This will release nutrients at scheduled intervals, keeping your plants fed without manual effort.

Step 4: Test and Adjust

Fill the reservoir with water and nutrients, then test the system. Adjust the flow rate and timing as needed to suit your plants’ requirements.

Final Tips:

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

- Regularly check the nutrient levels and pump functionality.

- Customize the design with additional features like a trellis for climbing plants.

With this DIY project, you’ll enjoy a low-maintenance, high-yield garden all season long!
