BuildASoil's goal is to create an outstanding reputation for transparency with regards to our recipes, ingredients and Methods. It is in this spirit that we are sharing this extensive report with you.

Notes from testing:
We did not detect any herbicide, insecticide, or fungicide compounds in your sample. When you see the result as < the MDL this is a non-detect.
The MDL is the method detection limit. This is as low as we can see on our instrument with certainty. Anything below this is a non-detect.
We also did not detect an fecal coliform in your sample. This was also below the detection limit. The salmonella test was negative.
You did have yeast and mold in the sample. (As any good compost should) We do not normally test for yeast and mold in the compost samples. (We tested because we wanted to know) They are also not required by the EPA as far as I know so I do not have any regulatory information on yeast and mold.
I included the EPA Compost Quality Standards for Class II Composting Facilities for your reference. It looks like all of the heavy metals tested are well below these standards.

If you have been reading about cultivating indoors with organic soil then you've heard of SubCool's Super Soil. I admit to starting with this mix and thought I was really doing something special when I first went for it. I bought all the stuff and was really excited to use it.
My results were actually pretty good, but I've since moved on I think you should too.
Besides the "base soil" being purchased instead of made from scratch, I have many other issues. All in all this taking bagged soil and adding worm castings and nutrients isn't a bad idea, but it can be improved upon and money can be saved.
Here is the Recipe: 8 large bags of a high-quality organic potting soil with coco fiber and mycorrhizae (i.e., your base soil) 25 to 50 lbs of organic worm castings 5 lbs steamed bone meal 5 lbs Bloom bat guano 5 lbs blood meal 3 lbs rock phosphate ¾ cup Epson salts ½ cup sweet lime (dolomite) ½ cup azomite (trace elements) 2 tbsp powdered humic acid
Now I'll go through each item: Read more.....
