Are the Neoprene Collars reusable or do they need to be replaced every time???

They are reusable. Not sure what your aero cloner looks like but I do aeroponics too and have found that rapid rooter plugs in the net pots work extremely well and I don't need a collar witht e plugs.

Do you think I could use 2" rockwool macro plugs in my cloner?? Or would they get too wet??

I have the 8-2" sites Daisy Cloner from American Agritech.

hey hound dog. I looked at your cloner on the web and it doesn't show me anything other than a picture of the outside. That being said I wouldn't want to give you the wrong information since I don't use this cloner. I'd stick with the neoprene collars though. The only reason I use the rapid rooter plugs instead of rockwoll is that you don't need to soak the RR plugs (as you should with rockwool) prior to using. I use 3" net pots with a RR plug and expanded clay surrounding them. I drop them in my aeroponic tubs, start my spray pumps and away I go. The plugs are pretty much soaked the entire time.

Welp, I have this cloner...and I am not sure it is so great It created mushy stems on a few of my clones.
