So I'm still trying to get my head around this. You need to exchange the air at night only to get more oxygen. Or both day and night to keep it fresh?
I don't think it is "stale air" issue. I run completely sealed rooms which only get their CO2 from tanks or from burners with no issues. Could it be a toxicity?? Like latent fumes from the paint? Are you running a carbon scrubber in the room? I have seen plants look like this when someone used paint which offgassed .. this can also be true of your pond liner. Many pond liners just like the original grow tents which used Poly had offgassing issues, I'd put money on the paint or pond liner. There are way too many people running closed rooms with ONLY CO2 .... true getting "fresh air" will help.. but so would a big 12in inline fan and activated carbon filter which would neutralize some of the toxic offgassing without wasting your CO2.
I dont agree with your statement about paint or off gassing correlating to co2. Ive ran into the problem with none.of those problems. My.problem was my room was so priperly built and sealed the co2 built up at night. It happens @HerbieHaze
How does co2 building up at night harm the plants? I've noticed that I can see peaks at night of 1600-2500 ppm, I've noticed that after a nice drench of a Tea, the co2 levels seemed to peak and I've always attributed that to the soil doing it's thing, and/or being healthy.
In my veg room, I run it sealed, no air in no air out and I don't supplement with co2 either, and it doesn't skip a beat. Pond liner floor and kilz primer with paint on top. I have a co2 monitor in the room just to check levels and it seems to hover at 400-600, and when I work in the room, it can peak at 1500+.
I've never vented any of my sealed rooms at night and I run co2 tanks. Now I have had major problems with propane burners and
not burning properly.
I'm very curious about this and the importance of venting at night, even if it's just for a little while.
Humidity can effect them pretty good. Just had the same problem with locking up after I moved them to the flower room. 30% and they got pissed! Hooked up the Huey and this morning they were already looking happier. Killer work bro loving the updates!
Interesting topic as I'm / was having some similar issue in my room a few weeks ago and the only thing I have been doing different to remedy the situation is flowering with the door open into veg .
All except 1 plant are now perfectly healthy , had a feeling it had something to do with stale air but still not sure , curious to see this topic play out
There is just something about no air exchange that I can't get a handle on but it's much safer for me. The only difference with the door open is humidity ? It's 40-60 open and climbing in the 70-80s closed . Which is another variable I am kinda unsure about as my suggested vpd should be 65 but I prefer high dark period and 55/60 lights on
@Confuten1 are you running that lad in there this run curios to see her perform again
I try n keep my humidity at 50-55 when drying, lower than that and ive noticed they dry to fast and it impacts smell and flavor in a negitive way, jus my experiences.I like around 60% or a little higher in veg/early bloom then around 50% after week 4-5. I dried everything at 45% or lower this last round and it really brought out the dank smells.;)
Yea high humidity is fine as long as you don't mind a damp wall here and there. I actually like the plants when humidity is high they seem super happy. At my old spot I had constant air flow in and out and a steady hum at 55-65 and plants were always great. It's been a leaning curve with the sealed room but I seem to be coasting now so knock on wood , I hope it stays that way for us both :) Glad your good as I know your needing a crop bad to fund this room .....
Yes sir, almost done tho. Luckily I still have room height, normally I overgrown them.The stretch be on.
They're pretty happy so I'm happy. Thnx for checkin inLooking like there in there sweet zone @Confuten1 great job their filling nicely!:D
Awesome thread @Confuten1 !! looks like ur hand watering those girls, i know how much work goes into that! moving pots around to create aisles and what not.. Much luck with your new project, even though to me it looks like you dont need luck! keep killing it man, glad you got the chance to step up ur game to a much bigger project. Im rootin for ya!
