Hey guys I need some opinions. I have always sprayed with a boom sprayer however this year I bought a 200 gal skid. My question is what is the best way to calibrate this sprayer? What is the average time that most of you can spray a 1000 ft2? What gallon/acre rate do most of you spray at? Most of the people that I talk to spray about 80 gpa(1.8gal/1000). I have a hypro d30 pump. At what pressure do you guys spray at with this particular pump? Any info would be greatly appreciated. Thanks.
