hydro store is. I'll go by there and give him my cards and sample bags and you can go in there and pick up both. Call me e-mail me and arrange to get your samples to me. As I said I just starting trying to figure out how to do this. First few guys I did analysis for I actually went and picked up their samples and sent them the results as a picture and message letting them know which plants were males. This also apparently will identify hermaphrodites.
