What is the maximum number of pots that can be run in one zone with Container Tenders, and what would the corresponding pump size be for optimum performance?
The maximum number of pots in one zone is totally dependent upon how big of a pump you want to use. Let’s assume you want to buy a small pump rather than a big one. Let’s also assume (for the sake of this example) that you want to place 2000 Container Tenders per zone. Now we can size the pump. 2000 units times the maximum flow rate from a Container Tender (1.25 Gallons per hour at 30PSI) equals 2,500 gallons per hour for one zone. Divide that number by 60 and you get about 42 gallons per minute. So you would need a pump capable of delivering around 42 GPM at 30 PSI. This is not to be confused with the suggested delivery rates of the Container Tender. We suggest lower delivery rates at lower pressures for longer periods of time. This calculation provides a maximum requirement to help select your pump. Keep in mind that there are many other factors to consider, such as elevation changes, the depth of your well or pond, and the size and length of your main lines; but overall, you will fi
