Controllers

Environmental Controllers, depending on the unit, can monitor your grow room or greenhouses temperature, relative humitidy, and your CO2 levels. They can turn on and off supplemental equipment like vent fans, air conditioners, dehumidifiers, and CO2 generators. These controllers can be adjusted to keep your environment at whatever you need it to be for your particular indoor crop. Some controllers are digital and run with a microprocessor and some units are analog and use traditional bulb probes to measure readings. A Higher Yield features Environmental Controllers from Plug-n-Grow Systems and Custom Automated Products (C.A.P.)
