Calibrating Your Sprayer for Holganix
Do you know what your spraying technique is? Each person has their own walking speed and other characteristics like longer arms that can speed up or deter the time it takes your technician to complete a lawn. How do you decide on the right spray calibration for your technicians?
The first consideration should be the end spray volume desired in terms of gallons per 1,000 square feet delivered. For most lawn care companies, the typical spray rates are:
- 1.5 gallons per 1,000 sq. ft.
- 2 gallons per 1,000 sq. ft.
- 3 gallons per 1,000 sq. ft.
Each spray volume has its benefits. By spraying at a lower volume (like 1.5 gallons per 1,000 square feet), you have more production per tank full. This means your technicians are dealing with less weight in their truck and higher production in square feet per tank. However, by spraying at a higher volume, you ensure that you are applying a better coverage of the plants and soil. Keep in mind that at Holganix, we’d like to see you spraying no less than 1.5 gallons per 1,000 square feet.
Once you’ve selected the spray rate you’d prefer to use, there are three additional measurements you must consider for spray calibration. The three measurements are:
- Pace – walking speed
- Width of spray pattern
- Volume of spray coming out of the spray gun
Any of the above variables can be changed. This means that there are numerous ways to spray and deliver the proper spray volume per 1,000 square feet. However, there are also many ways to deliver the wrong amount of spray. How do you calibrate your spraying correctly? Follow the example below for instructions.
