Hey @silvertop
the bamboo treatment i'm trying is a borax / boric acid mix that i learned from a recent online course with bamboo U. I am new to working with bamboo so there is a lot of trial and error for me right now. On this first attempt i didn't buy eonugh consumerbals and so now the treatment is on hold until more arrives. Everything is a learning process.
Interesting let us see how this treatment works when you start back up!!
