Damn it's strange how so many of us have this desire to put our knowledge out to the world

I recently revealed the optimal time to veg for MAXIMUM THC and only a few people cared.

Ahhhh, impossible.

There is no such thing that applies to all plants / growers. WAAAAY too many factors. But if you have strong evidence, perhaps we can make a generalization, but more likely a correlation.

I'm willing to debate it with you tho.

You will have to debate the people that wrote the paper that analyzed many papers on the subject.

secrets... I like ;)

Try UV-B for maximum something!

I have. Lots.

Should I add UVB Light?

Hello, I have been growing on a very small scale for about 4 years. I am always trying to learn more about growing and I know that I have so much more to learn. I also know that it's probably a life long process! I started with auto-flowers in a 2 x 2 tent with a horrible LED light. I also...

With full documentation, cannabinoid testing, and much more.

What else you got LOL. Just kidding.

Ahh, sounded like you were advocating for it's veracity. My bad.

Been along time since I been in school but I don’t think that’s how you write a citation?

I'm still sticking with the study that says UVB isn't worth the electricity it burns.

Cannabis Inflorescence Yield and Cannabinoid Concentration Are Not Increased With Exposure to Short-Wavelength Ultraviolet-B Radiation

Before ultraviolet (UV) radiation can be used as a horticultural management tool in commercial Cannabis sativa (cannabis) production, the effects of UV on cannabis should be vetted scientifically. In this study we investigated the effects of UV exposure level on photosynthesis, growth...

Ideal veg time for MAXIMUM THC revealed !!!

Study is here: https://www.frontiersin.org/articles/10.3389/fpls.2021.797425/full According to science and math via meta analysis. 42 days is the answer. Six weeks.

from that study:
"The objectives of this study were to: (1) characterize morphological and physiological responses of indoor-grown cannabis to UV exposure, and (2) investigate the relationships between UV exposure levels applied during the flowering stage and inflorescence yield and secondary metabolite composition of modern chemotype II cannabis genotypes."

Why would they be using chemotype ll if the idea is to determine the effects on THC?

 

[josefrahl]

Why would they be using chemotype ll if the idea is to determine the effects on THC?

Probably wanted to see the effects on both the major cannabinoids as Chemotype II contains both THC and CBD? Title says "..cannabinoid concentration not increased..", not just THC. Chemotype I is THC, II is THC/CBD, III is CBD.

 

[N1ghtL1ght]

Why would they be using chemotype ll if the idea is to determine the effects on THC?

I just wanted to point out that this was with a medical strain, whereas about 85% or so of all cannabis strains are type I. With which Lydon tested positive.
And that they did lack UVA & DLI. But it's hard to say that this is actually the reason, well it could be anything. Problem is there are many interrelated features affecting this....

This just means they have a theory. The data is flawed because it's from different studies which means different strain, environment, ect.. Now a study has to be done on various strains in the same environment with various veg times by one team to prove the theory.

 

[N1ghtL1ght]

Yeah they need to get to the bottom of this or render it as an artefact

 

[Aqua Man]

A study is always specific to its variables… the worst thing people can do is blanket results as a factual blanket statement as has been shown time and time again in the scientific community. To many variables to make blanket statements.

eg. at over 1000ppfd green become the most photosynthetic spectrum. Low ppfd it is the least.

Eg. Par range was thought to be the only photosynthetic spectral range until other studies proved this wrong… i haven’t read a study that has not had a flaw or potential misinterpretation point in it.

tldr: data from a study while can give a general concept is not applicable to being ised as fact outside of its specific study.

Secrets are the only thing you can take to the grave with you.. And maybe a check for all your money..

Were all the plants in the study identical clones?

It's 100% bullshit. Anyone can prove it. Plant a seed, clone it and flower right away then veg the other. I've never been able to notice any difference at all. Some might say otherwise, but I can't. It's always exactly the same.

You need to measure the THC. The study is not about the perception of getting high.
