Garden Controls Grozone CO2 Controller

Working as expected. Upon arrival, there was a small white plastic anchor that was lose in the interior of the device. I used a screw driver to open it up and snap the plastic anchor back in place. No real damage done, it must've just popped lose during shipping. Anyways, now its been up and running in my grow room for 3 weeks now and things look good. The CO2 controller doesn't have a monitor display, so I have a separate CO2 monitor to make sure the levels were actually where they need to be and the CO2 controller is doing a good job keeping it at the number its set at. I recommend getting a controller/monitor all in one, but I had a monitor already so I went the cheap way and just got the controller since I already had a monitor. All in all, I think its a good buy.

This thing is great! You won't get a digital reading but that's bologna anyways you're not gonna stare at it all day. This one has less Bells and Whistles than the other machines but it gets the job done. It's very efficient and doesn't take much space it's quite small. 1000 setting will take you to 1250. Set it and leave it, I covered my little in use light even though it won't turn on when it's dark I did it anyways.
