Environment Sensors

In order to create the ideal environment for your cultivar, it is essential to be able to accurately measure it.

There are many generic humidity and temperature sensors that are cheaply available. Some connect to a smartphone via Bluetooth and provide a graph of data while others incorporate a smaller LCD to display current readings

Light

See Measuring light intensity
