What size model you choose to order is dependent on a few factors.
• What is the composition of the landscape materials? Turf uses more irrigation water than a dense ground cover or shrubs with deeper root masses.
• What products are you interested in applying through your irrigation system? Some products have higher application rates than others.
• How often do you want to refill?
In the end, this last point is the one that is the ultimate determining factor. If you want to refill less frequently, simply go up in size. If you do not mind refilling more often, then you can get by with a smaller size than what would be recommended. The following table identifies a typical landscape configuration and sizes that can be served with each EZ-FLO main line model along with other sizing information.
Please note that coverage levels assume a 4-6 week desired fertilizer refill cycle for EZ001CX to EZ010-FX models. High capacity models (designated as HC) are designed for commercial landscapes serviced by professional maintenance companies. Property sizing for those units is based on a 2-3 week refill schedule. Growers and nurseries use other sizing metrics (pounds per square foot and PPM) which can be found in their related web pages.
