So let me expand on this. I dont see what these gas generators are doing that is any different than any other gas appliance.
Is there not CO as a bi product too when using a CO2 gen? isn't there or what is the risk of CO posion from using this in the grow room?Like on a furnace and water heater that is gas, you have to vent them. What is it that the co2 gen, gas stove, ventless gas fireplaces are doing differently? The bottom line why spend all the money for the fancy gen instead of just ripping apart a regulator and ignitor on a gas stove and rigging that up as a CO2 generator? Or another form of the question, why do furnaces and water heaters get vented?
I haven't done much research on this topic until just a bit tonight. have more pressing issues, but this will be important down the road. What I do know on the gens is this so far:
as the poster stated earlier is that a few of the models can be air cooled
also I learned that CO is only generated or being generated if the flame isn't (blue or white yellow, red, orange)
