I'm not exactly internet savvy, but I was looking for promix. Couldn't find any at lowes, or anywhere familiar to me. do you think they'd have it at smaller retailer's, if not is there anything at like Lowes or home depot that I can use?.I guess I may have to go someplace smaller. I'm looking for something with no fert,and I get that you have to add dolimitic lime, is that hard to get? Thanks again
