Grow Room Monitors
Grow room monitors from smart thermo-hygrometers to VPD meters and CO₂ sensors — track the numbers that decide your yield. App-connected options from AC Infinity, VIVOSUN and Bluelab, in stock in Australia.
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.

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.
Welcome to The Grow Guys
We built The Grow Guys from the soil up — well, coco and perlite. Before we sold gear, we bought it, ran it, and learned the hard way what's worth the money and what ends up in the shed. That's the filter everything on our shelves passes through. No sales scripts, no rebadged junk, no telling you what you want to hear. Just gear we'd run ourselves and advice from people who actually grow. Chasing higher yields, tighter flowers, or your first harvest? You're in the right place.
