Im licensed in Alabama and just getting started with my business. I plan to spray my yard this week to hopefully work out any kinks I just want to make sure my calculations are right and would appreciate any info you could provide. Heres what I got. My yard is 21k and my skid sprayer is putting out 2gpm and Ive calibrated myself to cover about 1000 sqft per minute. By my calculations, it will take 42 gallons to cover the yard...which will include the following 21 oz of Speedzone 10.5 oz of Resolute Does this sound anywhere close?
