This does not pass the sniff test at all.

I have one bottle of 4R Small batch Select.

This post doesn't pass the sniff test.

I called my own mold remediation contractor who tested and remediated mold.  

I'd certainly recommend doing some kind of environmental study given the chemicals and such that could have been used there but more-so I'd be curious if the city wouldn't have a testing requirement to redevelop. 

I started with 2 and wanted to test the waters, so far it’s luke warm.

Checkout section 469 of the tax code for material participation tests and what it all means.

Prior to that I went through the education modules and took the test to be able to be certified and make the purchase. 

I am willing to test the waters for awhile. 

Once you have a shortlist, sign up for an account with each one and test them extensively to see how they function.
