Troll? Really? Asking for you to back up your claim is trolling?
Get real.
If you cant post your evidence, cool. Just say so. But dont expect anyone to take you seriously.

Cannabis doesnt have some elusive one of a kind "stomata type") LOL
Most growers are well aware its classified as a C3.

Stomatal densities change in response to changing atmospheric levels of carbon dioxide. The fundamental process of photosynthesis. With C3s the stomatal pore area is sensitive to changing atmospheric levels. Its no where near as complicated as you're making it out to be.

VPD is an important. If you feel the chart on Wiki is inaccurate post your finding to prove otherwise!
It seems if you can't back up your specious information then you begin the ad hominem attack. It's one reason I usually stay out of the grow forums.

that's my exact plan and thoughts. Bought some plant stakes yesterday, will use them as needed.

as soon as i took screen out of the tent, i realized how much i enjoy taking my plants out or at the very least having full access to them lol

Next year my garage will be finished and i will have a dedicated room for growing ( 12x20 blank canvass) , i will probably try scrogging then, when i can crawl under the trees i plan on growing lol or walk around them.
I don't scrog either (though a lot of the pics I see look so organized and pretty)
I use stakes so I can spin my plants around or take them out the bloom room if needed.
As curious said, bring a few grows to a successful completion first. The boards can help cut the learning curve if you sift through the vacuous posts and bro science.
Judging from your plants you're doing just fine.

I like to think im a fairly smart dude, got a bit of common sense etc...

you guys are quickly making me feel dumb lol

here i am, trying to make sure the fkn water is not too yellow or green in that tester thing for ph, or make sure i dont forget to fill up humdifier lol

hopefully one of these days i can come back to this thread and actually understand the last 2 pages lol
We all begin at the beginning. Just file it away for future reference, keep growing and reading and applying what you read to what you grow.

His 1975 work on Cannabis is a classic. If you look at that page you'll see he discusses making textiles out of hemp and I have done that. Matter of fact I do still spin cannabis. LOL

Can you support your research into your statement, otherwise...

Ya start a thread lets get technical with measuring the temperature of the inner crypt of a stomata sometime.

Until then were at temperature probe placement for accurate air readings and arent even close to anything vpd related. His plants look fine.... what arexyou suggesting we apply 70% humidity to that 80 odd darenheight probe at canopy :-)

thanks man, i am very happy with their progress so far.

This board is great, i was spinning my wheels until i settled in here and started reading.

I got the basics before beginning my grow and any help i have needed along the way has been easy to get.

Thanks everyone for that

I find that talking to or being around growers with real knowledge and experience affects you in a positive way. Because the seeds have been sowed in your mind to explore techniques farther, thus you will begin to understand the whole picture. You can't beat actual experience in the field. We aren't trying to complicate things, just giving you our experiences over years and years of growing. You won't learn that in a book or Google.

Oh please dont take that post the wrong way, im delighted its happening in this thread and i am reading everything you are all writing.

Not really understanding alot of it yet, but i have confidence that i will one day lol

I have always appreciated knowledge, especially when i didnt have to pay for it!

I started growing over 40 years ago and have been a "pioneer" in the field. We never had Google or RIU to run to. So easy now that all this knowledge is at the touch of your fingers. What a fascinating world we live in. You are very fortunate to have growers step in and offer to help, whether you understand it completely or not. We just know it works, our ancestral grandfathers taught us to grow. lol

Yep, crazy world indeed.

I hope you guys dont mind, but im going to use your experience to my advantage any chance i get.
As your experience grows, you'll begin to understand what that plant is telling you is wrong or right with it by "subtle" changes in growth and looks.
One of the most "common" mistakes a new grower makes is "overwatering" which starts a whole chain of events. This is where the VPD comes in handy. You will understand why watering isn't consistent. ie, watering every 3 days. If your VPD is too far out, shit is gonna turn bad real fast. Then you have all these "symptoms" you begin treating to fix. You have to treat the cause, but you have to understand what is causing it to happen. It is a process. lol

Vpd is flawed by wind, it shifts cooling from free to forced and that is a massive change.

Once written as a definitive answer to the question 'Wind is neither natural or needed by plants'. This ties in with the forced and free cooling of leaf energy budgets.

Vpd is rubbish at a simple level, if you must quote at least quote its flaws and considerations or it simply isnt workable.

Marijuana grew to cope with a wider range of humidities, all found in human living environments so why change somthing that already works and we have already.

I spend a couple of months growing with my canopy at 105 and my RH at 10%, without awareness of my VPD deficit I could not bring a crop in and yet...

I agree, thats my point on vpd. Others were insisting it is the be all and end all and it should always be used.

Lovely plants :-)
Your posts are so convoluted. No one has made any such claim. You're the one claiming VPD to be a "simplistic load of hogwash". "Others" myself included are simply saying its an important tool of measurement to help new growers understand transpiration.
To which you replied:
Are you talking that simplistic chart on vpd which gives no species consideration to leaf morphology or stomata type let alone the other 12 readings that require complex lab and field equipment costing more than all my grow equipment put together and is highly detailed on wiki and researchgate?

Ive actually completed the equation based on estimations given from various sites and the answer is meaningless to us mere mortals and even less so without complex dli data to make interval adjustments in real time.

Another load of simplistic hogwash and unless at extremes dismiss all humidity readings as you do not yet truly understand cannabis.
Your "point" appears to be a failed attempt to at overcomplicating the issue.

No douche face im claiming the vpd data presented on riu is simplistic but in reality no pro greenhouse uses such basic howash but a far more complex system with way more other readings than general humidity and temperature.

The only peeps that overcomplicate things are you and a large percentage of new growers, this is not a vpd thread and im not so new like you here :-)

i posted a new thread in the newbie section, but you guys seem active over here so if you dont mind, ill post the pic and question in here

these 3 girls are only 8 days from sprout. Space cookies paradise seeds

the leaves have reached edges of solo cups and are turning down into cup on 2, also have roots coming out bottom of all 3.

this is usually signs to transplant, but it seems very early to me still. My first run stayed in solos for 15 days but were def much smaller than these girls at day 8

heres another " What would you do" moment

thanks for all the awesome info and help

How many 'pro greenhouses' have you run? My first encounter with the concept of VPD came from someone with a biochemistry Ph.D. who ran greenhouses in both academia and commercially.

Why can't you discuss things without all the angry offensive name calling? Finally you end up in irrelevancy. What does how long tangerine_ has been here have to do with the validity of her statement?

Thank you for the compliment on my plants. But you seem to miss the fact I was pointing out, but for my knowledge of VPD basics I could not be successful growing these plants, in that environment, at all.

Overall you can make some good points but your hostile aggressive phraseology, offensive name-calling, misunderstanding and misuse of basic english and inability to stay on topic render your posts next to useless.
