Clone Collar 3-Inch, Cloner Inserts with 8-Spoke Design, 50-Pack for Use with Net Cups in Hydroponics Growing Systems, Aeroponics, Cloning Machines, and Home Gardening

Good value and precut with a center hole makes them easy to support young plants in my hydroponic gardens.

The AC Infinity 4-Inch Clone Collars are the perfect addition to my setup, especially paired with the AC Infinity Net Cups. These cloner inserts fit seamlessly into the net cups, providing excellent support for my cuttings and keeping them perfectly positioned. With the 8-spoke design, they securely hold each plant stem without damaging it, which has really boosted my success rate for rooting.I love that they’re soft yet durable, so they grip each cutting gently but firmly. Plus, the flexibility of these collars makes it easy to swap out cuttings or adjust their positioning. They also handle water exposure like a champ; no signs of wear or breakdown even after repeated use.If you’re using AC Infinity net cups, these clone collars are a must-have! They make propagation so much easier and more efficient, and I can confidently say they’ve been a key part of my thriving garden setup. Highly recommend for any cloner or hydroponics enthusiast!

foam inserts that fit 4" holes. It works. Not much else to say.

Great product for clones, good quality at a good price

I know when reading reviews some said these weren't the right size for the cups they had, so I bought the ac infinity cups as well, and they fit perfectly. So buy them both and you can't go wrong.

These are a bit too small for what I needed them for but I may be able to use them for something else.

These work perfectly. Very content with my purchase.

These are thick enough to hold my seedlings in and work well have used this for chives and cilantro so fat next will be some dill and tomatoes to use it with
