CO2 sensor placement?

[soaringfast]

Where should my monitor be placed? I'm having a lot of trouble in my sealed rooms and I think it's too much CO2 because my monitor is hanging from the ceiling instead of the canopy.
I'm burning propane and using a sentinel chhc-4.

my problem is that my fan leaves are turning yellow and burn..
It's not a over nute problem or a water problem.

keep the sensor as far away as possible from the co2 output. air movement is key when using co2, so have lots of circulating fans and i always recommend and air dump/exchange, run it every 2 hours for enough time to exchange all the air in the room, a typical inline 6 for 15min should be enough for most rooms.

I thought the point of having a sealed room was not having any air dumps/exchanges...?

I guess he was giving his opinion
I gotta sealed room too, just try to put the co2 controller as far away as possible from your co2 burner

whats your ppms are you set to on your co2 controller?
