Pickling activity occurs even if you don't see any overt activity. One bit of evidence during the four-day primary pickling is the accumulation of tiny bubbles about the vegetables. They will collect and then rise to the top. If you gently tap the Perfect Pickler™, you can see them take off.

Also, the brine will begin to cloud up as the pickling activity creates billions of beneficial microbes.

As for the taste, the initial fermentation will produce a pickle flavor which will gain in flavor in the refrigerator over time. If it needs an herb flavor boost, you can add a sprig or two of thyme, oregano, parsley, etc. If you like garlic, chop and add. Red pepper flakes (about a 1/4-1/2 tsp) will intensify the flavor.
