Niwa Grow Hub+ Bundle with CO2 Controller, Carbon Dioxide Controller, CO2 Meter Monitor Day and Night Relay Function, NDIR CO2 Sensor for Grow Rooms, Includes Temperature, Humidity & VPD (Green)

Great controller , great price , did have some issues with C02 sensor, but they answered my question fast, and sent me out replacement fast, and kept checking in to make sure it was functioning. Nothing is perfect but they are there to make sure it ends perfect before they are done and then will tell you make sure to reach out if anything arises!!!!

Not that impressed, it works, not well, but works.Hard to fine tune. C02 needs work. Owner needs to talk with growers how to setup system properly. Environment continues to fluctuate up and down. Not good.

Pros:Easy setupEasy to useGreat for a grow tentGreat for home useRemote access with the AppThe app doesn't suck entirelyEasy recipes/ grow cyclesCons:The 15A limit can be an issue with Heat or AC. You are limited to a small heater, I am not running AC.Frequent disconnects from WiFi (even after it was locked to an AP and 2.4G SSID)Complicated recipes are hard to input and are limited to 7 phases per recipe. It would be nice to import or export the recipes and share them with friends.It is a nice product, but I had a lot of issues, but the CO2 sensor failed after 4 months.

Could not get device to connect. I finally succeeded in getting it to connect, but it never sent any data back from the sensor to my phone. BE CAREFUL ONLY 2.4

Value for money:Best product out there for the price. Easy to use and reliable. Highly recommend Niwa!!!!!

This product works really well. I am currently using it to track the temp/humidity/c02 in my mushroom monotub. It is very accurate and helps us to see when the c02 is too high and when we need to fan more.

I have used the Niwa for 4 grows now. 3 with the Co2 monitor. My results have been awesome using it. I have verified the accuracy of the co2 monitor with an Inkbird unit and they were close in readings. I think the only thing I would change is implementing functionality to increase the range of temps/humidity the unit allows. It is very specific in keeping your programmed settings, which for me at times can result in frequent activation of climate control devices.I would also like to add that the service when needed as been absolutely amazing. Responsive and helpful. I am very satisfied with this product.

It blows away the ac infinity controller that I had. So many issues with keeping the rt humidity it would climb to 90% you always had to keep a watchful eye on it. With you program it and forget it.LOVE IT
