Did you buy and read either book? Have u looked at shovelhandles previous or current grow logs? I am doing a grow log currently also of an all organic grow. U could follow that. Ill be posting recipes, methods, and techniques that I use to grow organic herbs. The EM and AEM u speak of are apparently certain specific products ( only found a little info in a google search). If they are introducing benificial bacteria, mycos, and beneficial micro organisms there great! Use them. Use them by the directions on the package and see how it works. If your growing organically the micro beasties are very important, and there is a lot of different products on the market to get them in your soil..
