Many years ago I made a very embarrassing (but interesting) mistake when up-potting my well-rooted starts.
I added the beneficial microbes to the new soil and transplanted 5 of the babies.
The next day I did the same for the remaining 5.
About 3 days later I realized to my horror that the 2nd batch had been amended with septic system microbes rather than the benificial microbes.
The containers were the same size/shape/color and located under the sink next to each other (duh, headsmack).
I was expecting a disaster since I had thrown in a good handfull but to my surprise, the 2nd batch with the anaerobic microbes did just as well as the 1st batch.
