Why has it taken so long for a company to get this right? Worth the wait, just. I was beginning to doubt the product would ever become available.

I’m very happy with grow sensor

I’m very happy with grow sensor. It helps me to keep everything dialed in. I started a crop before purchasing grow sensor and it was struggling. Once I put grow sensor to work I easily dialed everything in and my plants look better than the past 5 crops.

What a great sensor

What a great sensor, it literally measures everything you need and the software is easy to use. Tracking VPD, Co2 and Dli makes for healthy plants. The customer service is excellent, email replies within 24 hours.

Best sensor on the market

Ordered the sensor and it arrived with a tracking number when it was supposed to. I have had dozens of loggers and there all either very bad are far to much for what I needed. I have dyslexia and adhd and normally ditch products when I get frustrated. But with grow sensor I attached it to WiFi easily and set all my alarms after a few minutes. Great product

A little new friend in my groom

I rarely write reviews. But I am really impressed.

When I found the sensor on YouTube, I was immediately excited. Small, smart and all the important data at a glance.
Too good to be true?

As a technician and electronics enthusiast, I have been disappointed by many devices in recent years. So I took a closer look at the device on the website. I was surprised by the accuracy specified. It was mostly exactly what I had been looking for for a long time.
Other sensors with an accuracy of 3% to 5% are, for me, just devices that display something, but nothing you can work with accurately – but this device is very accurate.

However, it is only a sensor. And I was actually looking for a controller.

So I was even more excited when I read that it would be possible to use it as a controller soon as well.
I didn't have to think twice and bought one straight away, and what can I say?
I have NOT been disappointed since I got it, even without the controller function!

I've been testing the device for about a month now and it's not just ‘read the room’, it's like growing with your room.

Thanks to the sensor, I've already been able to change many things (such as lower CO2 at night), which has SIGNIFICANTLY improved the growth of my plants.
It was just as easy as promised.
Unpack – switch on – connect – be happy ;)

I love the device, the app is super intuitive and clearly designed, and all data is available anytime, anywhere.

When the controller function is added and the Growops grow diary (which I didn't know about when I bought it) appears, I'll be more than happy.

The price and performance are already just right. Everything else I've looked at is much more expensive or not accurate enough, and many users are disappointed (Trolmaster, Pulse, AC Infinity, Mars Hydro, Spider Farmer, Grow Control, and many more).

Here you can really see that it's by growers for growers.
And there's a lot more...

All the information you get on the website, the growing tips in the emails, etc. It's just fun and everything is on a very professional level.

So give it a try...

I already know that I'll probably need another device for my second tent.

Thank you, Theo, for this great device!!!

Worth the money

The grow sensor is a top of the line sensor that has everything you need in 1.
The sensor is very accurate and can be used in rooms larger than your average home grow!

This thing is dope, It isn't cheap but it does a lot for the money, so it justifies itself quickly. Looking forward to the irrigation box thing they are working on. If you need anything ask for Theo.

This is the right sensor for stress free growing 💗

This is the right sensor, if you would like to grow indoor. It will notifie you if you have any parameter offset. It will also help you if your setup that you use is off, like instance if you have to small vent for your tent, it will help you push the limits of growth higher( by adding more power to lamps, adding cooling system... ) . It earns you for every offset in VPD so maybe you will se that you need more humidity trough the day in that case you can add humidifier or too much, than you can add dehumidifier... It will write you suggestions what you can improve. Only thing I saw was if you put it in the middle of cycle because of stage your growth is in. But I talked to the guys and they will add also this option. I even land it to a friend and he improved yeald just because he saw what flaws he had in setup. Great work guys. , 👍 👍 👍 💪
I think I will buy additional one for mother plant, just so I don't need to move it around.

No BS only sensor you need, made by actual growers for growers

Imagine if you could design the ultimate all-in-one sensor for your grow room or tent—intuitive, comprehensive, and free from annoying hubs and subscriptions just to use the thing (looking at you Aroya). Growsensor has nailed it. Crafted by genuine growers for growers, this device ends the frustrating hunt for a reliable monitoring solution.

I've spent years DIY-ing multiple sensors because the market offerings just didn't cut it. Not anymore. Growsensor stores the data locally and I can access it remotely without hidden fees. The app is lightning-fast, displaying crucial data upfront, enabling informed grow decisions. Customizable alerts ensure I'm notified only when necessary, and the scalable, mobile-friendly graphs are a game-changer.

Integration with Home Assistant is seamless. It monitors everything I need, including live leaf temperature/VPD, PPFD, and CO₂ levels. Plus, I can connect my Teros 12 soil sensor directly. Kudos to Growsensor—I'll be equipping every room and tent with this innovative, user-friendly solution.
