Hey anti,

I have posted that study here, maybe 3 times before. I think tester uploaded it to his Google Docs account too. There are 3 other studies with respect to growing cannabis indoors I have uploaded, and I just found a new one from 2011 (it's still in press, so it might be changed a bit before it's fully published). I will upload that following study once I remove my personal info from the study:
"Factors determining yield and quality of illicit indoor cannabis (Cannabis spp.) production"
Wouter Vanhove, Patrick Van Dammea, Natalie Meer
Forensic Sci. Int. (2011), doi: 10.1016/j.forsciint.2011.06.006 (In Press)
Here is another I uploaded to Tester's Google Docs account you may be interested in; however, the paper does not use proper photon quantification, i.e., umoles:
"The propagation, characterization and optimization of Cannabis sativa L. as a phytopharmaceutical"
A thesis submitted by David Potter JP
In fulfilment of the requirement for the degree of Doctor of Philosophy (PhD) in Pharmaceutical Sciences, Department of Pharmaceutical Science Research
King’s College London; March 2009
One thing to note about that study you posted ... well, there is more than on thing to note, but the most important thing to note is that study the workers used only red light (from a LED) to irradiate the plants. I wrote a post breaking down that study, I will find the post and PM it to you. It's a good study for sure, but the fact the workers didn't use white light affects the direct useability of the result, to a (smallish) degree.

- Hey spurr, can you elaborate on how to use that pdf program to view and remove data, and expound upon exactly how such data is viewed so we can be sure and check that it has been completely removed?

Here ya go, brand new tool, hot off the presses! The other info I posted about PDF editors (to remove printed info on PDF pages) is still needed, because the tool "MAT" is for meta-data.
"WOOT! Fu*k Meta-data! New tool from Tor: "MAT"
https://www.icmag.com/ic/showthread.php?t=218777

@ all,

I have been waiting to upload the PDFs I got for everyone a couple of weeks ago, until this tool was released. I need to edit some meta-data from some of the PDFs, so you guys/gals can't find out where I live. I'll upload the PDFs as soon as I'm done sanitizing them for my info.

:tiphat:

Thanks everybody for all that you've done. i got a one that's been requested before. I want

The results of an experimental indoor hydroponic Cannabis growing study, using the ‘Screen of Green’ (ScrOG) method—Yield, tetrahydrocannabinol (THC) and DNA analysis
http://www.sciencedirect.com/science/article/pii/S0379073810001969

seems like Spurr already uploaded it once but it has since been removed somehow.

Also this thread has my vote for a Sticky

Darn,

I neglected to upload those most recent studies I got for people in this thread. Sorry! I'll do so soon, maybe by tomorrow.

@ Madres and Emil Muzz,

I'll try to get those for you tomorrow.

Still here, even after ~15 months ;)

maybe some of the more computer savvy users can access it through there. i personally cannot. i was never given a password option and when i download it it says "unable to unarchive into downloads. Operation not permitted"

thanks though.

Ha, we are missing each other by mere minutes. I just tested the download and it works fine. I compressed and encrypted the PDF with the passphrase "ilovecanna" (without quotes). Use WinRAR or 7zip to decrypt and decompress, not WinZip which sucks major ass. :)

You may have a corrupt download, re-download and try again. What browser are you using?

ive tried downloading it on Firefox and Safari, i have a Mac so i cannot use 7zip, i tried to download WinRAR's free trial but i cannot get it to do anything so i guess i failed. one sets their own limits, and i guess ive reached mine. F***ing hate it when i cant access information because of my lack of computer savviness.

thanks for tryin to help me Spurr.

LOL, it'll be okay. :comfort:

Here ya go, I just uploaded to a new file host, same passphrase "ilovecanna". But I think you're going to be disappointed with the paper itself:
http://www.ziddu.com/download/16810238/hydro_SCROG.zip.html

There is unofficial 7zip's for MAC, they can be found here ("p7zip", "EZ 7z", or "7zX"). Or just install WINE on your MAC and then you can run most Windows apps without an issue, including Windows version of 7zip or WinRAR, using WINE.

Perhaps searching for papers by Mechoulam et. al. will lead you to more research on uv-b
since "In the laboratory, Mechoulam has converted CBD acid to THC acids by exposing a
solution of CBD acid in n-hexane to ultraviolet light of 235-285 nm for up to 48 hours. This
reaction uses atmospheric oxygen molecules (O2) and is irreversible; however, the yield of
the conversion is only about 15% THC acid, and some of the products formed in the
laboratory experiment do not occur in living specimens." (Robert Connell Clarke)

This seems to be a personal communication which leads me to believe that actual
research must have been done to ascertain this data....a paper must exist somewhere...

:ying: kind regards from guineapig :ying:

Something from Mechoulam:
Cannabidiol: an overview of some chemical and
pharmacological aspects. Part I: chemical aspects
Raphael Mechoulam, Lumı´r Hanus
Chemistry and Physics of Lipids 121 (2002) 35-43

6. Photochemical reactions of CBD
In a review of the pharmacological work of his
group Loewe mentions that ‘‘. . . unwirksamen
Cannabidiol wurde nach Ultraviolet-bestrahlung
ein wirkstoffgehalt nachgewiesen . . .’’, but this
work was never reported in detail (Loewe, 1950).
We have found that irradiation of CBD in
methanol with a 450 W lamp in a Corex vessel
gave a mixture from which mainly isomeric 1-
methoxy dihydro CBD’s were obtained (Shani and
Mechoulam, 1971). However, irradiation in cyclohexane
led to the formation of some THC, in
addition to iso-THC, reduced CBD and the
addition product of cyclohexane to CBD, giving
cyclohexyl CBD (Fig. 6). These reactions indicate
that CBD is photoreactive and should be guarded
from light when stored.


And that 1971 article is attached. There is something similar in an article not by Mechoulam and not attached:
Allwardt, W. H., Babcock, P. A., Segelman, A. B. and Cross, J. M. (1972), Photochemical studies of marijuana (Cannabis) constituents. Journal of Pharmaceutical Sciences, 61: 1994–1996.
http://dx.doi.org/10.1002/jps.2600611225
The marijuana (Cannabis) constituents, cannabidiol, (−)-Δ9-trans-tetrahydrocannabinol, and (−)-Δ9-trans-tetrahydrocannabinol were found to be photoreactive. The only interconversion of these cannabinoids detected by GLC, however, was the conversion of cannabidiol to (−)-Δ9-trans-tetrahydrocannabinol. From a photoreaction mixture obtained by the irradiation of cannabidiol, a sample of (−)-Δ9-trans-tetrahydrocannabinol was isolated and identified by GLC, optical rotation, NMR, and mass spectrometry. A yield of 16% was obtained. The activating energy for the conversion appears to be in the 235-285-nm. wavelength area.

Well yeah but what about CBDA, wtf am I going on about CBD that wasn't the question. Well the only thing I can find on CBDA irradiation is:
Cannabielsoic acids : Isolation and synthesis by a novel oxidative cyclization
A. Shani, R. Mechoulam
Tetrahedron
Volume 30, Issue 15, 1974, Pages 2437-2446
Also attached, for hardcore Mechoulam collectors.
