2x3 Channel Cap–Designed by a Grower, for Growers

I started gardening last year as a way to relax and reconnect with something hands-on. That journey led me to discover hydroponics—a clean, efficient, and deeply rewarding method of growing plants. As I built out my indoor system, I realized I needed a better endcap solution for my NFT (Nutrient Film Technique) channels. That challenge sparked another passion: 3D printing.

Combining my love for hydroponics and my newfound interest in 3D design, I set out to create the perfect endcap. After testing and refining the design—growing everything from leafy greens to 3-foot jalapeños—I’m proud to share the result.

This cap fits standard 2"x3" NFT channels and includes a 3/8" inlet barb for poly tubing with a 3/4" outlet connection for your PVC drainage. It’s ideal for low-pressure systems and, when sealed with a food-safe sealant, delivers a leak-free, reliable fit.

If you’re building or upgrading your hydroponic setup, this is a small but essential piece designed with real grow experience behind it—and a lot of passion for the process.
