The bubbles are good at breaking on the surface to displace little water droplets on the clones stem.
But there are many ways to skin a cat, If the water pump can break the surface of the water you could get the same results too. But I find an airstone and airpump the simplest method.
And ordering from the US, with shipping it would be probably the same as just buying the expensive neoprene here (about 10€ or 12$ for a 10x10cm - 4x4" piece)…
Maybe I just have to deal with a loud bubbler cloner…
You sure could do 1 clone in each spot if that’s all you want. I could fit up to 8 in one neoprene puck if needed.
I’m going to be running SOG ebb and flow. Clones are meant to be separated for transplant into 5" netpots filled with hydroton and straight into flowering.
Roots are strong and can be tugged apart gently with ease
i used a big square of 1.5" styrofoam from a shipping box and measured and cut out circles with an exacto blade, then cut a slit from the one side to the centre. spray painted them black the same time i was spray painting the 5g bucket. for the mister i used a 360* sprinkler fitting on a fountain pump.
