Soil

I read an article a while back about this. Can't say for sure about the tiger bloom or the soil you listed but California, Oregon and some other states are requiring fertilizers to be registered to be sold and they must have them lab tested to make sure the metal levels are ok. In California, there is a list you get through CDFA. Unfortunately since it is a new "legal" market and still federally illegal it is hard to do enough research. There is still a lot of testing to be done to see what the long term effects are of these metals. When I heard this my first thought was, well people are eating food with these metals, but I guess smoking them released them into the body differently. Definitely something I am sure we will be learning a lot about in the next few years I hope.

Ist not quite clear to me , About what Kind of metal you are Talking of=? you mean heavy metals like or anythingmercury or something poisony=? But well … I personally never heard of the Things you write About... ( and i have to admit that i dont know clearly what you mean

@Greengirl420 Thats the first time I have heard that one , but I do know certain types of water like from a well etc can hold lots of metal but a RO filter can fix that . Not sure how you would go about solving the problem if it's already in the soil?? What metals are we talking anyway? Iron and zinc are beneficial to the plants .
