2Select components that can be constantly submerged in water Not all probes that are meant to take wet readings are designed to withstand constant moisture. Ensure the probes and monitoring equipment you have chosen are always intended to be underwater. Additionally, make sure all meters are placed at appropriate levels in your system so measurements are not gleaned at the bottom of the tank where sediment can build, and temperatures are different than at crop level. Place the meters and probes at or around the root level of your crops if possible. 3 “These surgical and calculated introductions of the plants’ needs can result in healthier and more robust plants.” Perform regular checks on the various systems in your autodosing array This should occur no less frequently than once per week. This includes checking, cleaning and lubricating (where appropriate moving parts are located) the probes, monitors, and lines. This last step is often overlooked but is important as nutrient sediment can get clogged in the lines. This can have detrimental effects on the crops as sediment can block the water flow entirely. If not caught in a timely fashion, none of the plants will get any of their needed nutrition and will suffer accordingly. To clear out any buildup of salt in your lines, it is advisable to run a cleaning solution throughout the autodosing system as per manufacturer’s recommendations and guidelines. The system’s filters should also be opened and inspected routinely to clean out any debris that may have built up over time. 44 Maximum Yield
