GROWNEER 60 Packs 2 Inches Garden Clone Collars Cloning Collar Inserts with 8 Spokes, Fits 2 Inches Net Pots, for Hydroponics, Cloning, DIY Cloner and Clone Machines

These are pretty solid quality at a great price.. I eventfully went rock wool cubes for cloning veggies, but that wasn't any fault to these just a last-minute change of direction.. if I end up coming back around, I have plenty unused collars on standby

Works as advertised.

These are perfect if you are into Aquaponics. But I was too hasty in my Amazon search to find the perfect insert for my little 2" plastic pots. Yes they will hold you small plant in the planter and yes they fit perfectly into a 2" plastic pot. Only issue is my application is for Aquatic Plants, meaning aquarium, so I needed them completely submerged. The density of the EVA rubber makes them extremely buoyant, and would require a heavy small rock to keep them down...but then there would be no place left for the roots. Ooops! I'm returning them and will keep hunting. But if I ever have an application where they don't have to be fully submerged, these would be my go-to's.

Made a diy cloning machine, 2 air stones and a 20-60 gallon rated air pump from Walmart. Glued down with aquarium safe silicone. Clonex solution. Excellent results.

Couldn't find any that were less than 2 inches. There a little large for the baskets that came with my kratky system, but might still be able to use them. Wondering if I can start seeds from scratch on these.

they seem to be doing finr. they don't absorb water to readily

The ez clone sells theirs for double the price and these are just the same. Saves me money thanks!

These are working just fine and should be plenty to last a while.
