Meet the HydroMesh 5-in-1 Environmental Sensor.
Measures your critical grow space climate parameters with best-in-class accuracy.
All the high end products in the the HydroMesh 8-in-1 Environmental Plus ePAR Sensor except we've removed the ePAR sensor.
Measure: 1) Temperature, 2) Pressure, 3) Humidity, 4) VPD, 5) CO2
This wireless mesh connected sensor just needs to be plugged into a standard USB-A connection point with the included link cable!
Accurate environmental data is important if you want to keep critical parameters in check like Vapor Pressure Deficit (VPD) and Carbon Dioxide (CO2). Keeping the VPD within recommended ranges has several favorable effects on your plants. Proper VPD leads to transpiration rates ideal for maximum growth rates. Too high of VPD will lead to high transpiration rates and "thirsty" plants which can make your crop steering endeavors very difficult. Too low of VPD may result in low transpiration rates with plants that don't "drink" much nutrient solution through their root system. This could lead stunted growth, nutrient deficiencies, or even mold related problems!
Proper Carbon Dioxide (CO2) supplementation has been shown to increase yields by as much as 30% or more. As a reference, outdoor CO2 levels around the globe currently range from approximately 350 ppm to 450 ppm. The EN13779 indoor living air quality standard rates CO2 levels of 400 ppm to 600 ppm as "Medium Quality" and 600 ppm to 1000 ppm as "Moderate Quality" which is very typical for the spaces we live in every day. Your plants will achieve maximum growth rates in environments with CO2 the concentration 1500 ppm. Recall the old saying that "too much of a good thing can be bad"? Well CO2 levels that approach 2000 ppm can be fatal to your crop!
