A tip for getting the most out of a Pilot Light Co2 burner....

I recently purchased an older Co2 burner made by Green Air Products (CD-3). This unit has a pilot light.. which typically is not recommended for grow rooms as the pilot light burns all night while the lights are off... wasting Co2 etc.

I actually bought this burner BECAUSE it has a pilot light.. and here is why!

I have a veg room, and a sealed flower room that run opposite each other (The flower room is dark while the veg room is light and vise versa). While the lights are off in the flower room, I have a small duct booster fan that pipes the air from the sealed flower room.. into the veg room. Sealed flower rooms (imo) produce MUCH higher yeilds.. but with the pilot light burning all night.. Co2 builds up in the room needlessly (plants dont use Co2 at night). By setting the duct booster fan on a timer that runs opposite the 12/12 schedual of my flower room lights.. I can keep the flower room sealed during the day when I want Higher Co2, and then vent the Co2 into the veg room to help the kids grow up nice and strong. I set my veg room light timer for a 3 hour overlap at the start and end of the flowering day period.. so the middle 12 hours of veg time will recieve higher levels of Co2. Pilot light burners are not great for single room applications.. But it is working REALLY well for a 2 room set up! I hope this can give you some ideas if you happen to have one of these older burners and want to make the most use out of your propane! Hopefully it makes sense... LOL

Can you tell me how you hooked this up? I have a bunch of pipes in my unit and I dont know which one the gas is. Im deff going to need some pointers before hooking it up.

gas pipes will have threaded fitting. water pipes are usually soldered or brazed.

There is usually only one Flanged Fitting (the male end is tapered to match the female end).. it should be easily accessible from the outside of the unit as is the case with most burners. The CD-3 I bought had some funny style propane fitting that no one carries.. so I took that fitting off and rigged up a few natural gas fittings that went to a standard BBQ size flange fitting for propane. If you are unsure how to hook up your unit.. take it in to your local grow store for a lesson.. look up a video on youtube.. ask a gas fitter friend to have a look at it... ANYTHING you need to do to be sure you are doing it right! The last thing you want to do is play with explosives when you dont know what your doing! Be safe dude!

This is what a standard BBQ propane flanged fitting looks like... It hooks up to a standard BBQ hose and regulator. The extended cast iron fittings are what I needed to convert the original fitting to a standard BBQ fitting like this..

Can anyone tell me about tanks? I just found out that my space does not have a gas line, so I am thinking of bringing in a tank. Does anyone have a link for them? I am not sure where to start looking, since I dont know if I can use a propane tank or not.

I'm just curious how burning propane creates Carbon DIOXIDE, not Carbon MONOXIDE.

propane and natural gas burns clean(light blue flame) leaving only water vapor and co2 behind. CO2 generators are just tankless hotwater heaters modified to our pourpose. If anything lack of oxegen would be an issue if levels get to high.
BTW i work in the oil and gas industry
