How did you measure ethylene levels? What analytical work verified ethylene as the critical factor?
Sealed room plants off gassing ethylene and causing issues

I'll paint everyone a picture.
Theres a 30x30 sealed room with it divided by a divider with temp and humidity controls in each room. Air can still pass between rooms
Let's say you harvest 15 lbs
With all those drying plants in the same room as your veg plants you risk having high ethylene levels and poisoning your plants.
Just .5-1 ppm poisons a tomato plant and we all know weed has lot in common with tomato

I am not disagreeing with any of that, but I remain curious about the analytical methods. “Trust but verify.”
Didnt measure, testers are like $500
I came to the conclusion because of several reasons.
I have 2 friends who have sealed rooms, use same nutrients, co2, r/o and some of the same strains. Only difference is they don't dry there crop in the same area as growing plants. They never have this issue.
I've grown for years before moving here and never had this issue before.
I clone my next round a few days before I start flowing. Those clones always grow and veg just fine for months and like clock work everytime I harvest they always start there deficiency. Never before I harvest.
Every new round I tried changing something to fix the issue and nothing worked.
If it's not nutrients, over/under watering, vpd outta wack, environmental/light shock. Then what's else could it be besides ETHYLENE.

Me veg room is only 10×20 and that not big enough for a veg and dry area.
Next round I'll have a 10×15 room built for drying. Separated from any living plants
Don't think I'm overwatering these roots

Your implying that I can grow a healthy veg plant for months, no issues but whenever I harvest all of a sudden I cant grow a healthy plant anymore?
Trust me it's not a watering issue. It's just not. If it was it would show itself at all times/ random times. Not just coincidently evertime I harvest
You've had very good advice from @cannabineer @Dr. Who and @greg nr the only thing I can add is move your drying to a separate area if you can. If you can't then up your air exchange which requires stopping CO2.
Good luck on your grow.

He can verify his hypothesis empirically by increasing room air exchange to promptly evacuate ethylene or he can move drying to another room. Although I dry in the same room I flower remember I have MASSIVE air exchange, far above what's necessary.

I'm not here to argue. If you don't believe me just go get fucked.
Th at is one of the greatest replies I've ever read. I m not joking when I say that line should be in a song. Hell it should be in a novel.

I installed a 8in exhaust fan in my drying room running 24/7 a few days ago but it was a few days to late and my plants were already damaged.
Next round I'll have a separate drying room so this doesn't happen. Plus I'll exhaust my flowering area for a few days just to make sure.

I run the Can-Fan Max-Fan Pro Series 8″ 863 CFM in my room and I dry in the same room. I think you'll be pleased with the performance. BTW check out your first page and look at the link Cannabineer posted for you. It has some interesting info in it on the mechanism of injury via excess Ethylene.
Thanks cannabineer very good Info. Anyone doubting the effects of ethylene buildup should read this.
Sorry man didnt mean your post. I was talking about the people laughing and poking fun at my ethylene claims.

No, not much at all...Really
Now a tropical plant - that's better. More closer care related... I like to tell newbies to learn to grow an African Violet. If you can get that to bloom,,your now ready to run cannabis without much trouble at all.
Oh good for you.... I put my first seed to soil at 15. That's 46 years here.
So after reading up to the end this mourning. I understand how 15lbs would make a dif.... But that's a lot of material for that sized room, and vegging.
Kinda strange you would dry in your veg room. My Veg rooms are warmer and more humid then the bloom rooms. In fact, the bloom rooms are about perfect to dry it in. Low 70's and 50% RH on average.
You didn't need to ditch your burner. Simply clean or replace the nozzles.
You don't gas the veg room do you? Not very cost effective, if you math it out. In fact I run stand alone buildings. They are set up to run gas but, after doing some test runs. I found it's actually more cost effective to NOT gas... Go figure. (I can run rotation vs fill it and run a room - This keeps my patients in material much better. It also allows for a broad selection of strains for them too.)
You do shut the gas down early so the plants can ripen,,,correct?
Now, back to your area and it being "sealed" for gassing.....Now you do know you still have to turn the air over in those rooms,,,right?
Not like normal but, it works much better with those high 80"s temps and high RH in the upper 70's,
To use an environmental controller.
Set your high temp limit and the high RH limit and as the area hits that. It shuts down the gas, turns on the exhaust and cooling system. When the system gets the temps and RH down to it's programmed start point. It shuts down the exhaust and cooling. Turns on the gas ans starts the whole thing over again.
This is the most effective way to run gas in a "sealed" area!
Naturally at night everything shuts down as far as the gassing goes. So you then do a long exhaust to rid the high RH from the area and run cooling if need be to do about a 10 - 15 degree drop in temps for the night right?
The plant uses that temp swing in it's growth patterns. I say you have to have it, to grow for potentials.
At any rate, you worded your first post in the thread like you were looking for help. Not like you were giving information..
You ARE correct about the ethylene gas !!
Down the road man....
