Veggie Growing with NFT Aquaponics
Budget-Friendly Veggie Growing with NFT Aquaponics Designs
Growing your own veggies doesn't have to break the bank. One of the most cost-effective methods in aquaponics is using an NFT (Nutrient Film Technique) system.
Borrowed from hydroponics, this method is perfect for those looking to grow small herbs, lettuce, and strawberries on a budget.
Let's dive into how you can set up your own NFT system and the benefits it offers.
What is an NFT System?
An NFT system is a popular method in both hydroponics and aquaponics. It's simple to set up and involves using a large enough PVC pipe (typically 90mm-100mm or 4-5 inches).
Holes are drilled along the top of the pipe to accommodate net cups where the seedlings are planted.
How Does It Work?
Water flows through the PVC pipe from one end to the other, creating a thin film along the bottom of the pipe. This water film carries nutrients from the fish tank to the plants. Here’s a step-by-step breakdown:
Drill Holes in PVC Pipe: Create evenly spaced holes along the top of the pipe to fit your net cups.
Insert Net Cups: Place the net cups in the holes and plant your seedlings.
Water Flow: Ensure water flows through the pipe, no more than halfway up the pipe, to nourish the plants.

Key Benefits of NFT Systems
Cost-Effective: Using PVC pipes and net cups makes this one of the cheapest methods for aquaponics.
Simple Setup: Easy to assemble with basic materials.
Ideal for Small Plants: Perfect for small herbs, lettuce, and strawberries.
Cautions and Limitations
While the NFT system is budget-friendly and effective, there are a few things to watch out for:
Avoid Using Pool Noodles: Some people use cut-up pool noodles as a cheap alternative to net cups, but they often contain neurotoxins that can be harmful when cut.
Not Ideal for Large Plants: Fruiting plants and large plants with extensive root systems can become top-heavy and clog the pipes, causing instability and poor water flow.
Nutrient Distribution: Plants closer to the water inlet receive more nutrients than those further down the pipe. Long pipes can exacerbate this issue, leading to uneven growth.
Perfect for Indoor and Small Spaces
The NFT system is excellent for indoor setups and small spaces. For example, you can place one over a turtle tank. In such setups, basil can grow up to 18 inches before the pipe clogs. It's a simple, affordable solution that works well within specific parameters.
Conclusion
An NFT system is a fantastic, low-cost option for growing small vegetables in your aquaponics setup. While it has limitations, particularly with larger plants, its simplicity and affordability make it a popular choice for beginners and those with limited space.
