In the past decade, urban farming movements and technological advancements in agriculture sparked a rebirth to hydroponics, a fairly old farming concept which dates back to ancient times, possibly as far as 600 B.C. Hydroponic systems allow farmers to take water, space and time efficiency to a whole new level, where they get to grow a higher yield of produce in a sustainable and controlled environment with less overall energy expenditure.
Building a hydroponic garden is a rewarding way to grow fresh produce year-round, and if you are reading this blog, you have likely been thinking about starting your own hydroponic journey, perhaps you are already in the midst of setting up your system. We are here to give you some quick tips on what to look out for, before you set sail to grow your first batch of hydroponic produce!
Step 1: Gather Your Materials
Hydroponic System: Choose between NFT (Nutrient Film Technique), DWC (Deep Water Culture), or Ebb and Flow systems based on your space and plant type.
pH Meter: Essential for maintaining the correct pH levels in your nutrient solution.
EC/TDS Meter: Measures the electrical conductivity (EC) or total dissolved solids (TDS) in your water, ensuring your plants receive the right amount of nutrients.
ORP Meter: Monitors the oxidation-reduction potential, which can help in maintaining water quality.
Step 2: Set Up Your Hydroponic System
Assemble your chosen hydroponic system according to the manufacturer's instructions. Ensure all components are securely connected and that the system is placed in a location with adequate lighting. If natural light is insufficient, consider investing in grow lights to provide the necessary spectrum for plant growth.
Step 3: Prepare the Nutrient Solution
Fill your hydroponic reservoir with water and add the appropriate hydroponic nutrients. Use your pH meter to check the pH levels, aiming for a range of 5.5 to 6.5, which is optimal for most plants. Adjust the pH as necessary using pH up or down solutions.
Next, use the EC/TDS meter to measure the nutrient concentration. Follow the guidelines for your specific plants to ensure they receive the right nutrient balance. Regularly check and adjust the nutrient solution to maintain optimal growing conditions.
Step 4: Plant Your Seedlings
Carefully transplant your seedlings into the hydroponic system. Ensure the roots are well-placed to receive ample nutrients and oxygen. Depending on your system, you may use net pots, grow cubes, or other planting mediums. Maintain proper spacing between plants to allow for adequate growth and air circulation.
Step 5: Monitor and Maintain
Consistent monitoring is key to a successful hydroponic garden. Utilize your water analysis tools to keep track of water quality and nutrient levels. Regularly check the pH meter, EC/TDS meter, and ORP meter to ensure all parameters are within the desired range.
Perform regular maintenance by cleaning the system, changing the nutrient solution, and inspecting plants for any signs of pests or disease. Keeping a log of your readings and observations can help you fine-tune your system for better results over time.
