I know it's not ideal. I've have some of the lawn care operators in town tell me that they started off with backpack sprayers but I'm not sure how it's possible. Last year I used my Solo back pack for spot spraying only but I want to get into more organic applications including Nature's Lawn Aerify Plus and Biodethatcher. The back pack was fine for spot spraying applications, certainly not idea but good enough. It was just a little extra work. I calibrated the sprayer today and figured I'm putting down a most impressive 0.03 oz per 1000 square feet. Yes, that decimal is in the right place. Does that sound correct/possible? I am going to have to swap nozzles and try again.
