For worm bins, most have had a 'Meh' experience with liquid Bokashi/EM-1. The stuff is just so damn acidic.
However, Bokashi BRAN works like a champ and I use it all the time. Think of it as bokashi in a dried form, but without the 3.2 pH of the liquid. I'll add my food (coffee grounds and/or comfrey), spread it out, sprinkle a handful of BB over it and done.
Just getting ready to make some as the 50# bag of wheat bran arrived. The feed&seed guy doesn't stock it (or perlite either), but will add either to his weekly order and call me when it comes in. $18 for 50# of wheat bran and $16 for 4cf bag of perlite. Now, I just need to get a fresh garbage can from HD to put it in. The one I had used is full of mix.
The smallest bottle of EM-1 is fine, because it makes more than a few gallons of AEM (Activated EM), and well under a gallon is more than enough for 50# of bran and doling it out a handful at the time ...........
You'll see as you use it.
