NFT Hydroponics Kit | NFT Hydroponic System | Nutrient Film Hydroponic System
How nutrient film technique works, and which kit to pick
An NFT kit is a hydroponic system built around one idea: a shallow stream of nutrient solution running continuously along the bottom of a closed channel, past bare roots, and back to a tank to be pumped round again.
The word that matters is film. The channel is not full. The roots sit partly in a thin flow of solution and partly in the humid air above it, which is how they get water, nutrients and oxygen at the same time. A root sitting in a full, still tank drowns; a root in a moving film does not.
Why there is no growing medium in the channel
Because the flow does the work, an NFT channel does not need to be packed with anything. That keeps the system light, keeps it clean and makes it easy to look at a root and see how the plant is really doing.
Seeds are still started elsewhere, usually in a sponge or plug, and the seedling moves across once it has a root worth calling a root.
What you get and what you supply
Both of our NFT kits arrive as the growing part: the gullies, the connectors that join them, the grow pots and a water pump.
You supply the reservoir, the nutrient solution, the growing medium and the seeds. The reservoir is worth choosing rather than grabbing: opaque, with a lid. Light on nutrient water grows algae, and algae is the single most common reason a first system disappoints someone. The channels are already closed for exactly that reason.
The one real weakness of NFT
It depends on the pump. Stop the flow and the channel drains, and the roots have only what is left in the grow pot.
Short power cuts are nothing. A long one in warm weather is worth reacting to. If your supply is unreliable, deep water culture is the method that keeps working when the electricity does not, because the roots are already sitting in the water.
Which kit
The 36 cup kit is one slanted bank of 36 sites, 98 x 108 x 52 cm, at €249. It stands against a wall or on a balcony and the slant means every site sees the same window. This is the sensible first NFT system.
The 108 cup system is three tiers of sites, 140 x 96 x 50 cm, at €399. The tiers are the point: plant them a fortnight apart and you cut continuously instead of facing a glut. You can run one tier to begin with and bring in the others later.
If both sound like more than you need, the 11 cup deep water culture system at €79 is a single aerated tub with nothing flowing. It is the easiest thing here to start on.
What we are not going to tell you
The listing this page replaced said hydroponic crops beat soil grown ones for nutrition and flavour. We have taken that out. Nutrition comes from the variety and the growing conditions, not from the absence of soil, and taste depends on what you grow and when you cut it.
It is also worth saying plainly that hydroponic produce cannot be certified organic in the European Union. Regulation (EU) 2018/848 requires organic crops to be grown in soil.
What NFT genuinely gives you is a crop grown in a space that has no soil, in a season that has no weather, cut minutes before you eat it.

Common questions
Where can I find resources for successful gardening with an NFT Hydroponic System?
Online forums, hydroponic gardening books and our product pages all cover NFT growing, and you can email us with any question.
Can I mix different types of plants in one NFT Hydroponics Kit?
Yes, but ensure they have similar nutrient and light requirements to coexist harmoniously without competing for resources.
How does an NFT Hydroponic System impact the flavor of herbs and greens?
Flavour depends on the variety, the light and the nutrients. Picking fresh just before eating is part of the appeal of growing your own.
What are the differences between NFT and other hydroponic methods?
NFT focuses on a continuous flow of nutrient solution, while other methods may use static water (DWC) or media-based (ebb and flow) approaches.
Can I use tap water in my NFT Hydroponics Kit?
Tap water can be used, but it's recommended to test and adjust its pH and nutrient levels to suit the specific requirements of your plants.
Are there any common problems with Nutrient Film Hydroponic Systems?
Common issues include algae growth, nutrient imbalances, and pump failures, but these can be managed with regular maintenance and monitoring.
How long do plants take to grow in an NFT Hydroponic System?
It depends on the crop and conditions. Leafy greens and herbs are among the quickest; check the seed packet for the usual time to harvest.
Do NFT Hydroponics Kits come with a warranty?
We do not publish a separate manufacturer warranty. If a kit arrives damaged, faulty or with parts missing, tell us and we will put it right under our returns policy and EU consumer law.
What is the best way to monitor plant health in an NFT Hydroponic System?
Inspect plants regularly for growth, colour and signs of stress, and adjust the nutrient solution or light as needed.
Can Nutrient Film Hydroponic Systems be automated?
The pump keeps the solution moving, and grow lights can run on a timer. Nutrients are added by hand.
How do I choose the right NFT Hydroponics Kit for my space?
Consider the available space, types of plants you wish to grow, and your budget to select a kit that meets your gardening goals.
What kind of support structure is needed for an NFT Hydroponic System?
A sturdy frame or shelving is needed to support the channels and reservoir, often included in the kit or easily constructed.
Are Nutrient Film Hydroponic Systems complicated to set up?
They are designed for easy assembly, with most systems being straightforward to set up, often requiring just a few hours to get started.
What makes an NFT Hydroponics Kit ideal for urban gardening?
The compact, tiered frames suit balconies and small indoor areas where there is no garden bed.
How does the nutrient solution in an NFT Hydroponic System get replenished?
The solution is replenished by adding water and nutrients to the reservoir based on plant needs, ensuring a continuous supply.
Can NFT Hydroponics Kits grow root vegetables?
While best suited for leafy greens and herbs, root vegetables can be challenging to grow in NFT systems due to the shallow channels.
What kind of maintenance does an NFT Hydroponic System need?
Maintenance involves monitoring the nutrient solution, cleaning channels to prevent clogs, and ensuring the pump remains in good working order.
Do Nutrient Film Hydroponic Systems require electricity?
They require electricity to run the pump that circulates the nutrient solution, making it essential to have a power source nearby.
Can I expand my NFT Hydroponics Kit as my garden grows?
Many kits are modular, allowing for easy expansion to accommodate more plants or different types of crops as your experience grows.
What is the yield comparison between an NFT Hydroponic System and soil gardening?
It depends on the crop, the light and how the system is run, so we do not quote a comparison. Our NFT kits hold 36 or 108 plants at a time.
Are Nutrient Film Hydroponic Systems environmentally friendly?
We do not make environmental claims about our NFT kits. They recirculate one nutrient solution with a small pump.
Can an NFT Hydroponics Kit be used indoors?
Yes, with enough light from a window or grow lights, so you can grow through the year.
How do I maintain my NFT Hydroponic System?
Check and adjust the nutrient solution, clean the system between crops and keep an eye on plant health.
What is the cost range for an NFT Hydroponics Kit?
Prices vary from affordable starter kits o advanced systems, catering to various levels of hydroponic gardening interest.
Do Nutrient Film Hydroponic Systems save water?
They recirculate the nutrient solution back to the reservoir, so you top up only what the plants use and what evaporates.
What types of plants are best suited for an NFT Hydroponic System?
Leafy greens and herbs such as lettuce, basil and coriander.
Can beginners use an NFT Hydroponics Kit effectively?
Yes, it's designed for simplicity and efficiency, making it accessible for beginners with detailed instructions for setup and maintenance.
What are the advantages of a Nutrient Film Hydroponic System?
No soil, a steady supply of nutrient solution to the roots, and tiered frames that fit a lot of plants in a small area.
How does an NFT Hydroponic System function?
A pump circulates nutrient solution along shallow channels. The roots take up water and nutrients from the film while the upper roots get air.
What is an NFT Hydroponics Kit?
An NFT Hydroponics Kit is a complete setup for growing plants in a water-based system where a thin film of nutrient solution recirculates, feeding the roots directly.
