Hydro Clone Cloning Collars - Black - Hard - 2-in (50.8 mm) - 65 Count

Reusable Light-Blocking Collars for Steady Cuttings - 2-in Neoprene

Cuttings that lean or shift in a cloning machine root unevenly, and light reaching the rooting zone invites algae. These opaque neoprene collars grip the stem, keep the cutting upright, and shade the base. Because they are reusable, you can clean them between cycles and use them again.

This unit holds 65 collars, enough to fill a cloning machine or run several batches for a hobbyist or regular indoor grower. Commercial propagators can order several units to cover larger cloning runs.

Key Features & Benefits

• Neoprene construction — grips stems firmly without a rigid clamp.
• Opaque black — blocks light from the rooting area.
• 2-in (50.8 mm) size — suits cloning machine slots of that size.
• Reusable — clean and sterilize between cloning cycles.
• Made in the USA — domestic manufacture.

Who Should Use Hydro Clone Cloning Collars

Growers who propagate cuttings in aeroponic or hydroponic cloning machines will find these collars useful, whether they run a home setup or a larger operation.

Frequently Asked Questions

Q: What size are these collars?
A: They are 2 in (50.8 mm). Check that your cloning machine slots or net pots take collars of that size before ordering.

Q: Will they fit my cloning machine?
A: They are intended for most aeroponic and hydroponic cloning machines. Confirm the slot size in your machine's documentation.

Q: Can I reuse them?
A: Yes, the collars are reusable. Rinse off plant residue and let them dry fully before the next cycle.

Q: Why does the opaque material matter?
A: Opaque collars keep light away from the rooting zone. Less light in that area helps discourage algae in a cloning system.

Q: How should I clean them between cycles?
A: Rinse with clean water, sterilize with a method suited to neoprene, rinse again, and air dry. Store them somewhere clean and dry.
