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
