Neoprene Discs – Replacement Clone Collars for Aeroponic Cloning Stations

What are Neoprene Discs used for in aeroponic cloning?

Neoprene Discs (clone collars) hold cuttings upright in an aeroponic cloner lid, keeping stems stable while the cut end hangs into the misting chamber. This reduces movement and stress on fresh cuttings, helping them sit in the spray zone correctly and encouraging faster, more consistent root initiation.

How many Neoprene Discs come in a pack, and what colours are included?

Each pack includes 25 Neoprene Discs in multiple colours (such as orange, blue, green, red, purple, and yellow). Colour coding makes it easier to track batches, varieties, or dates without mixing labels or guessing later.

Which cloning machines are Neoprene Discs compatible with?

They’re designed for standard aeroponic cloning stations and often fit other cloners that use similar lid or net pot hole sizes (commonly around 5cm). To be sure, measure your cloner lid opening—if the disc seats snugly without falling through, it will work.

Are Neoprene Discs safe for plant stems?

Yes. Neoprene has some give, so it’s much gentler than rigid plastic collars. It supports soft, fresh cuttings without shredding or pinching stems, as long as you don’t force very thick stems into a tight slit.

How do I insert a cutting into a Neoprene Disc correctly?

Gently open the pre-slit collar with your fingers and slide the stem in without yanking. The stem should sit snug, not crushed. Let enough stem hang below the disc so the cut end is clearly in the misting zone, not sitting dry or submerged in water.

Do I need a humidity dome when using Neoprene Discs?

Often yes, especially in the first few days. Cuttings don’t have roots yet, so high humidity helps prevent wilting. Trimming large leaves and keeping temperatures stable also improves early survival.

What water temperature works best with Neoprene Discs?

Most growers aim for cool-to-mild water temperatures, roughly in the high teens to low 20s °C. Water that’s too warm encourages bacteria and slime, while very cold water can slow root formation.

Do Neoprene Discs help reduce algae and light leaks?

They help block light entering the reservoir and reduce splash-back through lid holes, which can limit algae growth. However, algae can still appear if water is warm and light finds a way in—good hygiene and temperature control still matter.

Should I use cloning gel or powder with Neoprene Discs?

You can, but it’s optional. Many aeroponic systems root successfully without hormones if conditions are dialled in. Using gel or powder may speed things up, but cleanliness and environment are more important than additives.

Are Neoprene Discs reusable, and how do I clean them?

Yes, they’re reusable. Wash with mild soap and warm water, rinse thoroughly, and let them dry completely. Some growers also use a short soak in a mild sanitiser, followed by a very good rinse. Always start new runs with clean, dry collars.

When should Neoprene Discs be replaced instead of reused?

Replace them if they’re cracking, stretched, permanently smelly, or holding slime that won’t clean out. Reusing worn or dirty collars is one of the biggest causes of cloning problems.

Why are my Neoprene Discs slipping or cuttings popping out?

This usually means a size mismatch, stretched collars, or stems that are too thin or top-heavy. Make sure the disc fits the lid snugly and the stem thickness matches the slit so it grips without crushing.

Can Neoprene Discs be used for herbs, vegetables, and houseplants?

Yes. They’re commonly used for cloning herbs, vegetables, and ornamental houseplants in aeroponic systems. For food crops, keep your system clean and avoid letting residues or biofilm build up.

What’s the biggest mistake people make with Neoprene Discs?

Reusing dirty collars and expecting clean results. Neoprene Discs help, but cloning success still depends on hygiene, stable temperatures, humidity control, and good cutting technique.
