      Grow Room Monitors That Catch Problems Before Your Plants Do

      Track Temp, Humidity, VPD and CO₂ From Your Phone

      App-connected monitors like the AC Infinity Cloudcom B1 and VIVOSUN Bluetooth Hygrometer push live readings and alerts straight to your phone, so a heat spike at 2am doesn't cost you a run.

      Grow Room Monitors That Scale With Your Setup

      Start with a simple wireless thermo-hygrometer, or step up to multi-sensor units like the GrowHub E42A and Enviro-Pro that read temp, humidity, CO₂ and VPD in one display — and drive your gear from the same readings.

      Picked by Growers Who Actually Use Them

      We're a grower-run Tasmanian shop with 14 years behind the recommendations. Every monitor here is stocked in Australia and backed by real advice on where to place it and what numbers to chase.

      Complete your environment setup: grow room environment control, environment controllers, CO₂ controllers and monitors and grow room temperature control.

      FAQs

      Do I need a grow room monitor if I already have a controller?

      Yes. A controller only sees its own sensor. A standalone monitor at canopy height verifies the conditions your plants actually experience and cross-checks that your controller is reading true.

      Can I check my grow room from my phone?

      Yes. App-connected monitors like the Cloudcom B1 and VIVOSUN Bluetooth Hygrometer send live readings and alerts over Wi-Fi or Bluetooth, wherever you are.

      Where should I place a monitor sensor in a grow tent?

      At canopy height, shaded from direct light and out of the path of fans and humidifier output. That's where your plants live, so that's the reading that matters.
