I live in an area close to the great lakes and we are known for having this real black rich soil. It was an old swamp that was drained over 100 years ago and the local farmers have been using this soil since. They grow all kinds of crops in the soil. When dry its very sandy in texture and blows the dirt right through your clothes. When wet it gets muddy and sticky sometimes gets a hard crust on the surface. I work in the soil at a R&D greenhouse/ facility for a major university. We do almost all of our work in the herbicide/pesticide/fungicide experiments. I know of some people that grow around the farm area but not high quality bud. I am curious if this soil would be good for autoflowers (i might just have to test). I was thinking of just taking it and adding some perlite and see how things go. My main concern would be soil born disease. I heard you can heat up the soil to sterilize some of the pathogens. I discussed about this soil last year but didnt have the right connects. This year i took some of the soil, 4 different locations, and sent them in to be tested. Was wondering if someone could help me out or should i just get some promix and be done with the thought. Researches have told me the soil is very unique and is the best that they have seen??? I have heard that the organic matter in the soil is rather high around 40%-60%. I am just gonna give you the averages on the 4 locations numbers appear to be consistent. I also am not a soil expert i have only grown in
or Promix.
