🌿 Hydroponic NFT/Kratky 🌿 - 3D Printed Downspout Cap Set


Are you passionate about growing your fresh greens like lettuce, basil, parsley, or thyme? 

If you're interested in hydroponics, the NFT (Nutrient Film Technique) system or the Kratky method are excellent choices to kickstart your journey. With our innovative solution, you can easily assemble a hydroponic setup using a few key components.


To create a functional NFT system, you'll need a downspout, a storage tote, and a 1/4" pipe. 

To create the Kratky system, you’ll need a downspout. 

However, one challenge you may encounter is sealing the end of the downspout effectively. That's where our simple yet effective solution comes in - a specially designed downspout cap blind/blank or with an elbow connection. Using this cap and a bit of silicone, you can easily seal the downspout's end.


Installing the caps is a breeze, and if the silicone is applied correctly, you can ensure a leak-free system. The caps are printed from PETG plastic, which offers exceptional durability and versatility. PETG exhibits remarkable UV resistance, making it suitable for both indoor and outdoor applications, including areas exposed to direct sunlight.


We take pride in offering eco-friendly products, and our Vinyl Downspout End Caps are no exception. Made from PETG plastic, they are fully recyclable, making them an environmentally responsible choice for your hydroponic setup. When you are ready to replace them, you can do so sustainably, knowing that they can be recycled and repurposed.


Upgrade your hydroponic gardening experience with our 3D-printed downspout cap set. Enjoy hassle-free assembly, efficient sealing, and the assurance of using high-quality material for your hydroponic NFT system. Start cultivating your own fresh and flavorful greens today!

⚠️ Attention ⚠️

Silicone inside the perimeter of the end caps or the Vinyl downspout is a must! 

To achieve the best results, let the silicone cure for a full 24 hours before adding water to your hydroponic setup. 

This curing time allows the silicone to form a strong bond, enhancing its waterproof properties and ensuring a long-lasting seal.


The package includes JUST the end caps.

The vinyl downspout and the silicon are NOT included.



NFT hydroponics, or Nutrient Film Technique, is a popular hydroponic system that uses a thin film of nutrient-rich water to grow plants without soil. This system is highly efficient and requires less water and nutrients compared to traditional farming methods, making it a great option for sustainable indoor or outdoor farming. With NFT hydroponics, plants grow in channels or tubes, which are easy to set up and maintain.


The Kratky method is a simple, no-electricity hydroponic technique. Plants grow in a container with a nutrient solution. No refilling is needed; the solution lasts throughout the growth cycle. It's popular for leafy greens and herbs.
