Materials Needed

To build a DIY hydroponic drip system, you will need several materials:


The first important material is the tubing. This will be used to transport the nutrient solution from the reservoir to the growing trays. Make sure to choose tubing that is durable and flexible enough to be easily maneuvered.


Next, you will need a pump. This is an essential component of the system as it will be responsible for pumping the nutrient solution through the tubing and delivering it to the plants. Look for a pump that is suitable for hydroponic systems and has the appropriate flow rate for your setup.


A reservoir is required to hold the nutrient solution. It should be large enough to accommodate the amount of solution needed for your plants. Consider using a container that is opaque, as this will help prevent the growth of algae.

Growing Medium

A growing medium is necessary to provide support and stability for the plants. You can choose from various options, such as perlite, vermiculite, or coconut coir. Select a medium that is compatible with hydroponic systems and offers good water retention.

Net Pots

Net pots are specially designed pots that allow the roots of the plants to grow through them. They should fit snugly in the growing trays and provide adequate space for the roots to flourish. It is recommended to have one net pot per plant.


A timer is crucial for automating the watering cycles in your hydroponic system. It will control the duration and frequency of the nutrient solution delivery. Make sure to find a timer that is suitable for hydroponics and can be easily programmed.

Nutrient Solution

The nutrient solution is the key element that provides essential nutrients for plant growth. You can either purchase a pre-mixed solution or create your own by combining the necessary nutrients in the right proportions. Ensure that the nutrient solution is specifically formulated for hydroponic use.

pH Test Kit

Maintaining the correct pH level is crucial for the success of your hydroponic drip system. A pH test kit will help you monitor and adjust the pH of the nutrient solution. Look for a reliable test kit that provides accurate readings over the desired pH range for your plants.

Growing Trays

Growing trays will serve as the containers for the plants in your hydroponic system. They should be deep enough to hold the growing medium and provide sufficient space for the plant’s root system. Consider using trays made of durable and food-grade materials.


Scissors are necessary for various tasks, such as trimming excess tubing, pruning plants, or harvesting crops. Make sure to use clean and sharp scissors to avoid damaging the plants or introducing any contaminants.

Step 1: Set Up the Reservoir

The first step in building your DIY hydroponic drip system is setting up the reservoir. Choose a suitable container for holding the nutrient solution and place it in a convenient location. Ensure that the reservoir is stable and won’t tip over when filled with water. It’s advisable to place the reservoir at a slightly higher elevation than the growing trays to allow for proper water flow.

Step 2: Install the Pump

After setting up the reservoir, it’s time to install the pump. This component will be responsible for circulating the nutrient solution through the system. Place the pump inside the reservoir, making sure that it is fully submerged in the solution. Connect the pump to a power source and ensure that it is functioning properly.

Step 3: Attach the Tubing

The next step is attaching the tubing to the pump. Insert the tubing into the outlet of the pump, ensuring a tight and secure fit. If necessary, use hose clamps or connectors to ensure that the tubing is firmly attached to the pump. Extend the tubing from the pump to the growing trays, making sure to position it appropriately for efficient water distribution.

Step 4: Add the Growing Medium

Now that the basic components are in place, it’s time to add the growing medium to the growing trays. Fill each tray with the chosen growing medium, ensuring that it is evenly distributed and leveled. The growing medium should be able to provide proper support for the plants’ roots while allowing efficient water drainage.

Step 5: Place Net Pots

Once the growing medium is added, it’s time to place the net pots in the growing trays. Make sure to position each net pot securely in the tray and ensure that it is at the appropriate depth for the specific plant you will be growing. Remember to leave enough space between each net pot to allow the plants to grow without crowding each other.

Step 6: Connect the Timer

To automate the watering cycles, connect the timer to the pump. Follow the manufacturer’s instructions to set up the timer and program it according to the specific needs of your plants. Ensure that the timer is set to deliver the nutrient solution at regular intervals, providing sufficient moisture and nutrients to the plants.

Step 7: Mix the Nutrient Solution

Preparing the nutrient solution is a critical step in the success of your hydroponic system. Follow the instructions provided with the nutrient solution or use a reliable guide to mix the appropriate amount of nutrients with water. Take into consideration the specific requirements of the plants you are growing, such as the stage of growth and the recommended nutrient ratios.

Step 8: Check pH Levels

Proper pH levels are essential for the plants’ nutrient absorption and overall health. Use a pH test kit to regularly check the pH level of the nutrient solution. Adjust the pH as needed using pH-up or pH-down solutions, aiming for a pH range suitable for your specific plants. Consistently monitoring and maintaining the proper pH levels will ensure optimal nutrient uptake and plant growth.

Step 10: Trim Excess Tubing

Finally, after everything is set up and your plants are growing, you may need to trim excess tubing. Use scissors to carefully cut away any extra tubing that is not needed or may be causing obstruction. Ensuring that the tubing is properly trimmed will allow for better water flow and prevent any potential issues with the system.

By following these simple steps and using the necessary materials, you can successfully build your own DIY hydroponic drip system. Enjoy watching your plants thrive and reap the benefits of growing your own produce in a controlled and efficient environment. Happy gardening!
