I put the bokashi compost in my planters today. I noticed that there are tons of small bugs (fruit flies or gnat?) circulating around the planters. Does it mean that my bokashi compost was premature? I sealed it for 20 days instead of 14, but I did not see white mold. I found the smell pungent, but different from putrid. I am not sure if I did it correctly.
If you let it sit for 20 days, then it was not premature. 20 days is very good for bokashi. To control the small flies you describe, you can do 3 things: 1) bury the food waste a little deeper, 2) bury a little less food waste in each hole you make, 3) be sure to mix the food waste with the soil in the hole before you cover it up with soil.
These will help with your fly problem in nearly every case!
