Too much Co2?

Hi there,
I'm just wondering if it is bad to have too much Co2 in your grow room?
I've just Start growing... Still getting everything I need. Recently just got my Co2 sensors and tanks. I'm so happy to install the Co2 system. I've got some crazy reading. It is like 4k PPM!
I've contacted the supplier. I'm instructed to test out if is the sensor fail or the controller fails. I have a funny feeling that the environment is really high Co2 PPM?
Just said that is real. Is this place good to grow?

Something's screwed up and I'd get to the bottom of that before doing anything else.

How big is your grow to even need CO2?

Sealed room? If not you're just spinning your wheels and wasting money.

Won't hurt your plants if the CO2 is that high.

:peace:

Above 3k you will begin to feel the effects. That's pretty high.

To test it, take the sensor outside and don't breath near it. It should read around 410 +/- 10.

If it's still high, it's broke and needs either calibration or replacement.

First of all, I'm grateful for your reply.
I also need to apologize for all the information was not provided. You may be noticed that English is not my mother tongue.
Right, It is a semi-seal room. I don't have an exhaust fan to get the air exchange. I don't want the smell to go out either.
The room size is about 3m*2m*2.7m(hight) At the moment It has three 15gal bags of girls in it. I am going to move more clones into the room.
There are a few reasons for me to think that the sensor and the controller are both fine. As I mentioned, the supplier told to do a few tests. such as take the sensor out and see the reading, place the sensor in front of my breath and see the change of reading, place the sensor outdoor and recalibrate it, etc... After all the tests, the reactions/reading are with a reasonable range. Most importantly, it is what is underneath my grow room (I'm on the fourth floor). There is a Temple that burns incense 24/7. (the temple is located on the first floor)

Ok. Are you supplying CO2 from a tank that that sensor controls? Your room is about the same size as mine and I use an alcohol lamp to keep the ppm up to 1500 if I want. Think I'll sell my controller as I doubt I'll get a tank

All that incense should mask any pot smells at least. :)

Yes, I've got a tank for the Co2 supplementing the room. I would not dare to use fire to do so.
The new update is I think there was a leak in between the tank and the pressure gauge... I will go check it later after work.
This is so dumb if it really caused by missed installation...
The incense is not strong enough. I think about two weeks after the girls start to flower. I can only smell weed. I think the upstairs neighbors must feel odd.

Put a little soapy water in a sprayer and check the joints with everything under pressure. It doesn't take much to push the ppm up.

Make sure to check where the tube goes into the pressure gauge/flow tube. What tends to happen is the flow tube tips forward as you tighten the nut on the tank and the useful idiot putting it on grabs the flow indicator and twists it up. That causes the tube connection point to leak.

As said above, soapy water will find it.

I believe you’re from Alberta right? I may be interested in that controller

I'm not positive I'm going to sell it yet. I've only used it to see how much CO2 I generate with the alcohol lamps but if I get the addition built was thinking of investing in a tank. I have the solenoid and flow gauge too.

Going to sell my TrimPro Unplugged tho. Works good with buds that are already dried like when they are hung to dry but with fresh pot it just glues the sugar leaves to the buds and I like trimming fresh. Most of what I'll be growing is going to be for medicine and I can just trim off anything without sugar on it and freeze it all fresh for later processing.
