I have heard about EM solution and its positive things. But the EM solution I use have to be bought from the retailer. Since I don't know the contents in the solution I set back in using it. I scare that we would make and leave a disaster plant Parthenia like thing to our next generation.
So I prefer in making EM solution in my home with handy things available in my house itself. Please let me know the ways of preparing homemade EM of all kinds.
