Upgraded Gardyn Port Covers - 5 Pack

Upgrade your Gardyn system with our next-gen port covers—now sleeker, smarter, and more light-tight.

Designed for a precision fit with Gardyn openings, these covers feature an upgraded internal structure that blocks light from passing through the cap itself—helping reduce algae and protect your root zone more effectively than ever. The new low-profile design sits flush for a cleaner, more refined look that complements your setup without getting in the way.

Crafted from food-safe PET-G filament on dedicated PET-G 3D printers, each cover is built to last through multiple grow cycles while staying safe for edible crops. Sold in sets of 5 (1 order = 5 covers), they’re easy to install and even easier to appreciate.

Pair them with proper pH control and our PHLO water treatment for best results—while no cover eliminates algae entirely, these make it far more manageable.

Now available in our signature Shimmer finish: a light-catching surface that adds subtle sparkle without sacrificing function. All colors will be available in Shimmer soon.

Whether you're growing leafy greens or fruiting crops, this upgraded version is a simple, high-impact way to keep your system clean, protected, and looking sharp.
