Have plenty of dehus and definitely have the room well monitored (kind of an environment junky)

Honestly whatever this problem is/was it was extremely insidious in the sense that all parameters were as close to perfect as is possible and yet the general health was so low.

All I can really say is if you are running a sealed room with a generator and you are fighting phantom problems and a lack of general health do yourself the biggest favor and switch it up to bottled gas for a minute. LOL everyone has an old bottle laying around, and holy shit what a difference it made. Can't tell you how frustrating this was to deal with.

I know this thread is a year old but I just had to post because I have had the EXACT SAME PROBLEMS for TWO F'ING YEARS!

I just figured out today that my Sentinel VCG-27LP burner has a leak. Took me two years of trying everything under the sun to fix my plants to figure this out. I too have been running a new sealed room. I too questioned my skills and tried everything under the sun. I too had all the same problems: yellowing/dying leaves, curled downward "clawing" leaves and worst of all LACK OF OIL PRODUCTION leading to multiple harvests of schwag ass results...

I figured it all out by moving a single plant from my sealed flower room back into my mom room which is fresh air (no CO2 burner). The plant perked right up and looked much better within 24 hours. So then I turned off the burner in the flower room, closed the LP tank valve and opened the door to the room (to provide some fresh air). Within 24 hours of doing this all of my plants that were "clawing" in the previously sealed room perked up and pointed towards the sky. So I realized the problem had something to do with the burner.

Today I called Sentinel tech support. He wasn't sure what the problem could be and wouldn't admit that the burner could cause such problems but he asked me to try checking all the connections and burners for leaks. He said to make sure all threaded connections were snug and that the burners were screwed into the manifold well. He said I could spray soapy water on the hose connections...

...And that's how I FOUND A LEAK! At the end of the hose there is a black collar that screws onto the LP tank. Just behind that collar is a black plastic connector. It was bubbling when sprayed with the soapy water. I have not yet replaced the hose (I will do that asap and report back here) but I am really hoping that will be the silver bullet for all my woes for the past two years.

newestguy - I am really curious if you ever went back to using a burner. Did you? If so please provide details and results. Did you ever check thoroughly for propane leaks with your problematic burner? Thanks a lot for posting this thread. It has helped me work closer to resolving my longstanding problems...

Have any others known propane leaks to cause "clawing" and dying leaves?

BIG SHOUT OUT to the gnome for your help on other threads. My HydroFogger helped eliminate some of my symptoms and now I'm hoping the burner fix will leave me smoking nasty sticky goodness

propane leaks have been known to cause explosions... If ur going to run a co2 gen inside (a building code violation in most states I believe) check for leaks often... Cause it could go boom

[budleydoright]

ALL of the water heater burners are Chinese built, I imagine most of the purpose built are as well. The hose and regulator that come with these units are total junk. do yourself a favor and visit a local gas supply company in your area and have them make you one with a long hose, quality regulator and fittings.

Most propane devices are used outdoors and on demand, tanks are open and shut when used. We are leaving them unattended and wide open.

When my room smells like burn propane .. my plants look like shit .... I have a feeling it's dirty propane .... LAME

[Floridian]

I've seen this thread a few times but didn't respond because I really don't have anything to offer other than I haven't experienced these problems.My propane tank is in the room next door where I dry my plants,and in 13 years I have smelled it maybe twice,both times it was easily fixed by exchanging tanks.I run the hose through a hole in the wall because I need every bit of space I can get in my 8 by 8 flower room.I have been through two green air CD6's in a little over a decade,the last one lasting a good 7 years.I am glad I haven't experienced this "off gassing' problem,I wish I had some answers.I guess I just wanted to put in a good word for sealed rooms with burners,It's been great for me the biggest issue being heat

I'm such a tool aka hypocrite.. I was just re reading this thread and found this advice I gave.. I haven't checked any of my burners for leaks in at least 3 years... Lol. I guess I prob should

Always nice to be a step ahead but if things are/have been fine I wouldn't create a problem by tinkering with shit like that if things are perfect...

Pretty sure this thread might have saved my life. My burner was nice and blue little flower flames for probably the first 3 weeks, I was super anal about checking it, have a high quality co2 controller that measures in 100 increments so i knew it was working and I was keeping my ppm at around 1300. Suddenly out of nowhere was no end of drama with my plants.


Shit like this started showing up all over the place. Decided to go over everything, got to the burner and decided to take the panel off and found the burners like this.

Look just like ops, with the blackness but it's not a residue it seems burnt in from use.

Decided to turn it on and check the flames while I had the panel off, and yeah I think i might have some slight carbon monoxide poisoning just from taking this video. But yeah there is no way it's supposed to put off that much orange flame!

So what the hell is causing this? Has my gas gone bad? I have no leaks anywhere I checked the shit out of everything, every single connection on this thing with soapy water and there are no leaks. I pulled the burners off and tried to clean the black shit off but its like burned on.

I've ordered a carbon monoxide meter so I can see what it's putting out, and I'm gonna buy a brand new gas bottle and fill it myself but yeah if that doesn't sort it I guess its just a shit unit and it's not combusting correctly? I actually found a video I took when it was only a few days old and you can see its got a nice blue flower flame with only slightly orange flickers.

I AGREE

Not sure what to think or do with it now other then take it to the dump and just get a gas bottle.

But yeah just glad I figured this shit out before I dropped dead of carbon monoxide poisoning one day in my grow room with no one to find me lol.

A gasfitter is trained to properly clean burner manifolds.

Some grow stores offer this service but one has to wonder if it performed by a qualified person or simply someone trained to the task.

One suggestion, after installing a CO detector, would be to observe the flame periodically during light cycle. If the burner gradually becomes yellow, the issue may be incomplete combustion resulting from oxygen deficiency. Not easy to diagnose as each time you enter you are introducing fresh air.

i run my lights 24/7, i will be getting a new gas bottle and getting it refilled at a welding supply store where i know the gas is going to be ok, not have to worry about a shitty swap and go bottle from bunnings. the bottle im using is near on 10 years old so could be from old gas also.

i dont really want to take my co2 burner to someone to clean it is it something i could manage on my own? other then that i might just move to co2 bottles but if i can get this working would be great. and yeah hard to check when im in the room like you said.
