Temperature and Relative Humidity in Greenhouses and Cannabis Production

There’s a saying: “An ounce of prevention is worth a pound of cure,” and this is no different with your sensors and controls of the greenhouse/indoor farming equipment that you use and rely upon everyday. Similar to any controlled environment, it is vital to monitor and proactively interpret the pressure, temperature, relative humidity, carbon dioxide (CO2) supplementation, and irrigation of your growing space. Losing control of your environment can lead to cultivation headaches ranging from poor air flow to extreme temperatures; additionally, high humidity and low irrigation rates can lead to the spread of disease and viruses.  Continue reading “Temperature and Relative Humidity in Greenhouses and Cannabis Production”

Monitoring Center Pivot Irrigation Systems

You arrive at a large field, small sprouts peeking out of the soil. At the center of the field lies a structure connected to a span of pipe from which sprinklers hang. Trusses brace and support its weight. From the air, this field would appear to be a perfectly circular patch of green.

Center pivot irrigation systems are one of many ways to distribute water to crops. As its name suggests, this method involves rotating around a central pivot point. When the machine rotates, it releases water from the sprinklers and irrigates crops. (Agrivi.com) By using this system, farmers can ensure a uniform application of water across an entire field.  Continue reading “Monitoring Center Pivot Irrigation Systems”

Open Channel Flow Monitoring

Open channel flow monitoring is a method of measuring water flow rates in irrigation channels, streams, and storm water systems. It’s also used in wastewater processing for monitoring the effluent discharge. In most applications for open channel flow, weirs and flumes are used. For those of us not familiar, weirs and flumes concentrate the flow into a known cross sectional area, relating an accurate level reading to an accurate flow rate. The height of the water in the channel, going over the weir or flume, is directly proportional to the flow rate. Continue reading “Open Channel Flow Monitoring”
