I decided to start my own trip with Wabi Kusa several weeks ago. I didn't start them myself, but rather I purchased them off a member who was ready to part with them. He took amazing care to ship them and they were in amazing condition!
I'm now looking to make them my own. First think I'll be doing is adding some fluorite to the bowls.
I haven't cleaned the bowls up yet lol. Please forgive me.
Good luck with these! They are essentially the same setup as mine and the 2x mist per day is what I've been doing as well. We are REALLY dry here too. I do fill up the bottom sometimes to the level of the flourite and I think that helps for the times I forget to mist.
