Calibrate a 1,100-gallon hydroseeder for HP-FGM®, ET-FGM™, BFM, EFM™, Base Mulch and Biotic Soil Media™ using defined mulch mix rates, tank loads and coverage areas at multiple application rates. Tables specify pounds per acre, gallons per bale and square feet covered per tank, including options for centrifugal and gear/positive displacement pumps. Step-by-step guidance shows how to stake a calibration rectangle, calculate slope width and apply mulch evenly from two directions for better coverage on slopes.
