  • Damn good!!!
Color: CO2 Controller
This thing works the best out of all of the CO2 controllers. Don’t waste your time buying any other one I did and it was a waste. It’s very accurate and easy to use I highly recommend.

  • Great monitor/controller! Good as the more expensive competitors
Color: CO2 Controller
This controller works like a charm. Absolutely accurate and it couldn't be easier to set up. Numbers are large so you can see them and the co2 remote detector has a green light so it doesn't disturb light cycle of plants. $100 less than the leading brand and works just as well!

  • Only has low limits control-useless
Color: CO2 Controller
Wish I had checked it sooner as I'd have returned it. It's pretty much useless as it only has a single control. You can control a co2 solenoid with setpoints but no control for venting if CO2 is too high. So if it goes too high you're out of luck - or should I say your soon to be sick plants are! They must not use the product they design. Make sure you buy one that will also control venting if the CO2 is too high. ... show more

  • Love this controller
Color: CO2 Controller
I just wrote a review on the controller I had before this one and theirs was 2 stars. This controller is great! I love it! The value is excellent, the air quality stay in line with exactly what I need it to be and the installation was a walk in the park including set up. I was worried about getting my co2 levels adjusted but I had no issues getting it going. ... show more

  • Worth the price
Color: CO2 Controller
Needs to be recalibrate before you use it. Works pretty good for the price.

  • Super accurate
Color: CO2 Controller
This works fantastic so far , it’s very accurate, if I put it with pulse it’s all but identical, on opposite sides of tent it is about 80 ppm off but it’s the distance from the co2 emitter . Otherwise it’s right on .

  • Better than the leading brand, here's why
Color: CO2 Controller
This is a very accurate and quality CO2 monitor. A few reasons why it's better than the leading brand. One you can see all the data on the monitor itself (no need to go on your phone). Two, you're able to plug it in (no need for batteries). Third, it's $100 cheaper. Fourth, you can check CO2 levels in a range, per hour, day or week so even if you're away you can see if the CO2 levels rose or fell or remained steady. Fifth and most important for me is that it provides a reading every second, the leading brand only takes readings in 1 minute intervals (which you have to change on your phone from 5 minutes, what a hassle). This is the best CO2 monitor out there. ... show more
