GARDYN yCovers Silicone Hydroponic yCube Covers, 10-Pack — Stretchable Light-Blocking Inserts

GARDYN yCovers are flexible silicone inserts that snap onto yCubes to block surface light, reduce unwanted surface growth, and keep your hydroponic system tidy.

These ten reusable silicone yCovers are made to work with GARDYN vertical indoor hydroponic systems. They limit light exposure at the growing-medium surface so algae, mold, and other surface growth are less likely to form, while helping plants develop clean, healthier stems once they've progressed past germination. Lightweight and stretchable, each cover fits over an established sprout and can be removed as the plant canopy grows.

When should I put a yCover on my seedling?

Only place a yCover on a plant after the sprout is well established and has true leaves; applying it too early can trap excess moisture and interfere with germination. Wait until you have thinned seedlings and the individual plant shows sturdy stems before fitting the cover.

• Apply only to plants with true leaves and stable stems.
• Avoid using on ungerminated yCubes to prevent moisture buildup.
• Thin crowded sprouts before installing the cover.
• Use when ready to introduce plant food and transition from germination.

How do I fit a yCover without damaging my plant?

The silicone is intentionally elastic and durable, so stretch the opening gently around the stem and center the plant in the hole. Position the cover so no leaves are trapped beneath it, and adjust the stretch to minimize contact with the stem.

• Stretch the silicone slowly to avoid pinching the stem.
• Center the plant in the cover's opening for airflow and light control.
• Keep leaves outside the cover to prevent bruising and blocked photosynthesis.
• Use hands to mold the cover to the yCube rim for a snug fit.

What should I watch for so I know when to remove a yCover?

Remove the yCover when it begins to block normal plant growth, when the plant canopy naturally shades the cube, or if moisture starts to collect under the cover. Regular checks ensure the cover is helping rather than hindering development.

• Take off the cover if leaves or stems press against it.
• Remove when the plant is tall enough to shade the medium on its own.
• Inspect regularly for trapped moisture or surface buildup.
• Replace covers seasonally or if they show wear to maintain hygiene.
