I believe they are spraying at a lower volume out of there skids about 1 gallon per minute with a wand,i heard that from an ex employee and then i saw an article http://www.lawnandlandscape.com/ll0714-sprayers-spreaders-tips.aspx . I am spraying 1.5 gpm out of both of my skids at the moment (chemlawn gun with blue tips). I'd plan on starting to use the bigger skid to fill my ride-on, and i'd like to use my smaller skid to spray the smaller lawns, but at atleast at a 1 gpm rate or mabee even lower (i'd like to get 50,000 sq. ft. atleast out of the 50 gallon skid). so, just wondering if anybody knows of a good way to apply at a lower volume.. will some type of wand with a fan tip work? whats would the best technique be to get good results? trying to relate it to when i just used a backpack sprayer.. I hear some guys say hold it straight out front.. then somebody was saying move it back and forth as you walk. I did use a backpack when i start, but post emergent only, and i held it out front. that will take all day, i guess i can find some type of boom. I thought greendoctor had a thread with some sorta boom he had with pictures, can't really seem to find it at the moment.
