????? And u putting quotes around your sentences does nothing to prove you’re referencing anything meaningful
Except that's not what is in the studies you're blindly referencing. You described gravity, not vpd affecting plants.
I edited that post heavily now. You're looking to argue with me on a personal level and i have no motivation to do that. If you want to argue a point, i'll gladly respond. Otherwise, I'll just stick to trying to help new growers save their money and time spent without medicine. Nothing personal.?????

Maybe you don’t spend money on it and that fine thats your call. I’m not spending any money on vpd either. But in this post i think we’re on the right track. Vpd is a scientific collection of data. I agree your plants adapt. If youre growing the same plant for years in that environment, yeah don’t change it. But if you’re popping new seeds every grow and mixing it up then following vpd gives you a good chance that they will all be comfortable.Not to sound up my own ass, but i think i again am speaking casually and not specific enough. I'm answering to op basically and even mimicking his language in the first post. I'm seeing a new grower save that chart. Build it up to himself. Buying a humidifier and starting to mess with his girls chasing a chart he doesn't understand. I believe vpd is a major driving force in plants. I don't believe we know enough about it or plants or cannabis to say if it's relevant in an indoor garden situation. It's not something i would spend money on remedying or back it like it's proven science. Now, i don't use my anecdotal as real truth, but i couldn't get rh to do anything to a cut ive grown and harvested for 8 years, unless i started changing it during flower and that wasn't even visible, it just had "worse" sap tests.
I’m not at all I apologize. You can grow nice bud in a lot of different conditions, just thought this was a discussion of ideals. I’ll move on, peaceI edited that post heavily now.

Well, i would venture that almost every new grower with low rh is likely due to air exchange. They get a big online in a charcoal filter and suck out the humidity. I don't grow in low rh intentionally unless it was to test. A semi proper room keeps at least 45-55 just with plants in it. 70% is pretty standard for areas cannabis comes from, so theoretically should be good. I'm just not claiming anything vpd. All i'm saying is there is a habit on ig and here that the charts get passed around and screw with new growers. I've seen it personally and I'm sure we could search evidence here even. My initial approach was wrong and too casually worded. I attempted to remedy that in the following posts. My main point is this; if you're new, DON'T ACT ON THINGS YOU DON'T UNDERSTAND. Don't follow charts or blind hearsay. Research that actually physically happens and make an informed decision. And that all sources have issues.Maybe you don’t spend money on it and that fine thats your call. I’m not spending any money on vpd either. But in this post i think we’re on the right track.

In that case, my madeup quote was a direct joke of the first one i quoted because as i read these studies i noticed they mostly ended similarly.I’m not at all I apologize. You can grow nice bud in a lot of different conditions, just thought this was a discussion of ideals. I’ll move on, peace
Haha and I was too lazy to find and quote a good study. Peace broIn that case, my madeup quote was a direct joke of the first one i quoted because as i read these studies i noticed they mostly ended similarly.
Not to pester you, but nowadays you can find a study that says anything. People are actively publishing fake, endorsed studies to show how broken the system is now. You gotta read the whole thing and google the authors. It's a pain to search them now.Haha and I was too lazy to find and quote a good study. Peace bro
I try to read a lot and form my own opinion but yea I hear ya. My wife tried to convince me it was ok to put skin cream containing lavender on my young son after me telling her lavender contains phyto estrogens she tried to justify it because she found ONE single study ,by a group of women no less, that found it’s estrogenic effects were insignificant. Bahahaha I found five that said otherwiseNot to pester you, but nowadays you can find a study that says anything.

Yeah, i mean we didn't even touch on genetic influence and individual plant reactions. There are a lot of variables involved. Everyone here who helps people knows that feeling. Need to get garden walkthroughs going on oculus rift over the net.I dont go by the vpd chart. Right now I am about 20-30% humidity and 50% in the summer and flowers come out fine. Have tried flowers of the same cut using the VPD and they come out no different. IMO the chart is for all plants in general.
Funny how common these things run along plant growers! I have a very strict diet due to illness but i cut out phytoestrogens and all pseudo hormones cause i have to actively monitor my test. Can't really test it now though cause i'm on hrt.I try to read a lot and form my own opinion but yea I hear ya.

I like to go by the K.I.S.S theory. It’s made my life so much simpler and the way I grow this wonderful plant we all cherish.Holy hell, I hope some newbie doesn’t stumble across this thread and just give up Growing. Haha.
Well the paper you shared concludes that 0.8 kpa has yielded more than 0.5 kpa in tomato plants and anything over 2.2 stressed them out.VPD is another way to measure relative humidity. It is not used to keep plants in the made up sweet spot chart for weed forum use.
As always I suggest reading anywhere other than weed forums for pertinent info.
Here is Michigan university explaining it.
It’s just another tool we have to dial in our environments for best results.

I don’t know why you believe there is no sweet spot. I think the study you shared proves there is.
Can i ask for your personal experience with a sweet spot? Do you keep at a certain rh? Anecdotal evidence? I have no intentions to answer to it or anything, genuinely interested.Well the paper you shared concludes that 0.8 kpa has yielded more than 0.5 kpa in tomato plants and anything over 2.2 stressed them out.

No as it told you i didn’t invest in “vpd”. May humidity is usually 60-70% and temps are 23-26. So i’m already in the ball park.Can i ask for your personal experience with a sweet spot?
