The superb GSE Temperature, Humidity and Negative Pressure Controller digitally manages your fans based on how hot or cold the grow room happens to be and how much water vapour the air holds. On top of this, you’ll also find a negative pressure setting that will stop a grow tent from sucking in and prevent the escape of undesirable odours.
With these 3 different areas of control covered, the device allows you to more precisely tailor plant growing conditions, making any changes to fan speeds gradually and automatically to maintain your indicated preferences.
So what will you find when you unpack the GSE Temperature, Humidity and Negative Pressure Controller? There is an array of simple yet effective 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.
Effectively used by indoor gardeners over the entire year, the GSE Temperature, Humidity and Negative Pressure Controller suits most grow tent set ups and can comfortably look after identical sizes of intake and extractor fans (opting for a smaller intake fan here inevitably leads to slightly poorer results).
