oxyCLONE oxyCERTS - 1 7/8", Blue, pack of 20

Reusable Foam Inserts for Gentle Clone Support, Pack of 20

A cloning site insert that pinches or holds too tightly can damage a fragile stem before it's had the chance to root. oxyCERTS are soft, non-toxic EVA foam inserts fitted to the oxyCLONE system, using a no-pinch design that holds delicate clones securely through propagation without crushing the stem.

This pack of 20 inserts is sized to fully restock or expand a single oxyCLONE 20-site system, in 1 7/8 inch, blue.

Key Features & Benefits

• Soft, non-toxic EVA foam — holds clones without harsh or damaging material against the stem.

• Resists fungus, bacteria, chemicals, and heat — holds up to repeated use in a propagation environment.
• Does not absorb water — keeps a consistent shape and performance across reuse.

Frequently Asked Questions

What system are these inserts designed for?

oxyCERTS are fitted specifically to the oxyCLONE cloning system. They're sized to match the system's cloning sites rather than being a universal insert.

Will these inserts pinch or damage clone stems?

No, they use a no-pinch design built to hold a delicate stem securely without crushing it. That's part of what distinguishes oxyCERTS from harder foam or rubber inserts.

How do I clean oxyCERTS for reuse?

oxyCERTS clean easily with warm, soapy water and are built to resist fungus, bacteria, chemicals, and heat across repeated propagation cycles. They also don't absorb water, which helps them keep their shape over time.

What size and color do these come in?

This listing is the 1 7/8 inch size in blue, sold in a pack of 20. That pack size is enough to restock or expand a single oxyCLONE 20-site system.

What material are oxyCERTS made from?

They're made from soft, non-toxic EVA foam. That material is chosen for its gentleness on stems along with its resistance to fungus, bacteria, and repeated moisture exposure.
