This excellent digital fan speed controller takes temperature into account whilst operating to ensure good grow room conditions are constant and also provides a negative pressure setting that helps stop unwanted smells from getting away.
If your maximum preferred temperature is reached or exceeded at any point, the GSE Temperature and Negative Pressure Controller kicks in and gradually boosts airflow to subtly re-establish a suitable indoor climate.
Key features include easy-to-use dimmer style settings, a remote 4 metre temperature probe that can be extended up to 50 metres, a sealed water resistant cover, plugs with flap-lids and a low voltage sensor.
The GSE Temperature and Negative Pressure Controller is perfect for most grow tent set ups.
