Clone Collars, Disc inserts with 8 Spoke design, 4-inch, 50-Pack

AC Infinity 4-inch Clone Collars hold cuttings upright in hydroponic and aeroponic cloners while their roots form. This pack of 50 is made from soft, pH-neutral EVA rubber with an 8-spoke design that grips the stem without pinching it, and each collar compresses to sit snugly in a 4-inch net cup. Reusable and waterproof, they last cycle after cycle. Quick Bloom Lights is the official Australian importer: stocked in Sydney, shipped domestically.

Gentle support for new cuttings

A fresh cutting needs to stay upright with its base in the mist or water, and it needs the stem left undamaged. The 8-spoke centre flexes around stems of different thicknesses, holding them firmly while relieving pressure as they grow, so there is no pinching, bruising or rot at the contact point.

Made to reuse

Smooth EVA rubber is waterproof, pH-neutral and safe for plants, and it cleans up easily between batches. The collars compress to fit 4-inch net cups and cloner sites snugly, so cuttings stay put, and the dark colour keeps light off the developing roots below.

FAQ

Which size do I need?

Match the collar to your net cup or cloner site. These fit 4-inch cups; we also stock 2-inch, 3-inch collars and matching net cups in 2, 3 and 4 inches.

How do I insert a cutting?

Push the stem through the centre so the spokes close around it, with enough stem below the collar to reach the water or mist. Then press the collar into the net cup or cloner site.

Can they be reused?

Yes. Rinse and sanitise them between batches and they will last many cycles.

Do they work in soil or coco?

They are designed for hydroponic and aeroponic systems, where the collar is what holds the plant. In soil, coco or starter plugs, the medium supports the cutting instead.
