Hello. I am interested in soil testing and I hear Lesco sales centers will do this for customers. I was wondering if this is something that is done on-site while you wait (is that possible) or does it take weeks for it to be sent off? The local extension service takes 3 - 4 weeks and I am looking for a way to reduce that turn around time. The extension service charges $15, is LEsco competitive with that? Thanks!
