sorry. I'm NOT in the US and where I am simple possession of such books would also bring jail time, so no. I have not read any book other than what's on line.

perhaps EM is only labeled and sold as such in this part of the world, though I've seen it mentioned on organic farming sites which do not address cannabis.

though I have looked through some grow journals, they don't appear to be applicable to my situation/style of cultivation. I was just asking a generic question and looking for someone with hands on experience.
