[edit] Is this Plant Bianual?

I came to Wikipedia because I wanted to know if Cannabis is a One year, two year or more plant or if it has to be fertilized to create offspring for the next year as it dies. I dont know my self and It would be nice to know. 11:30 GMT+2 Feb 12 2007

Cannabis is an Annual plant. It completes its life cycle within a one year period. When grown outdoors, cannabis plants generally complete their life cycle between spring and fall.

_{--Big.thompson 12:26, 7 May 2007 (UTC)}

Under normal conditions, it is annual, but can be kept as a perennial if suitable conditions are maintained year round and is not allowed to flower. Alternatively, if the plant is kept in the vegetable state, it will never flower and continuously grow, unless it happens to be C. sativa subsp. sativa var. spontanea (ruderalis) or has the hybrid gene.

_{--MunkyJuce69 3:17, 8 May 2007 (UTC)}

[edit] Leave as it is

Indoor cultivating section is more of sub info than a topic on its own. It would be too spercific to move it aswell.

I support one very large article concerning Growing Cannabis. I do not see the need to split up each topic into small stub articles then make readers bounce around over 10's of pages to get all the info. Lets just keep it all on one kick ass page Harris77 22:10, 22 January 2007 (UTC)

god, smoke more weed man. you are so uptight :p :) :)  :y 68.190.191.115 17:27, 11 September 2007 (UTC)

[edit] Cultivation for non-drug purposes

Does the article include any reference to or description of cultivation for non-drug purposes? Laurel Bush 10:49, 10 August 2005 (UTC).

[edit] Cleanup formatting & Image placement

I think the images add a depth to the article that really gives character and helps flesh out the (rather dry) content. However, I think that their placement (seemingly without any order) detracts from the story. I haven't really got any idea of how to clean up the image placement, and I would prefer to not lose any images from the article. Would anyone like to step up and help out with the formatting? I think it could even be a FA if it got cleaned up sufficiently. The information is there, along with sources and images. Avriette 10:41, August 26, 2005 (UTC)

[edit] Split article?

Seems to me the article should be at least three separate articles:

• Cannabis (drug) cultivation
• Cannabis (fibre) cultivation
• Cannabis (seed) cultivation

Cultivation regimes depend very much on the purpose for which the pant is being grown. Laurel Bush 15:46, 31 October 2005 (UTC).

I disagree. While the article is of a fair size, splitting it into catagories is not the answer. I agree growing cannabis is quite complex, but how exactly does that warrant a split in our article here, could we not simply improve it further as one? What I would suggest is having more imagery in the first half of the article, perhaps moving the grouped images up somewhat. Relating images to specific areas would help, Ie. Seed picture next to germination, flowering marijuana plant next to the flowering section, et al.

If however, you feel as if the cultivation is not adaquately explained then please by all means suggest any ideas for improvement we could implement to the content. Bear in mind though that Wikipedia is an encyclopedia, it is possible to be simply too in depth for many readers. One could quite easily lose encyclopedic tone, quality and reader-appeal by overcomplicating certain sections. This is another reason not to split in what is already a broadly based and in my view an all emcompassing article. The article still needs much work, but fragmenting it is not the answer. -- D-Katana 19:17, 1 November 2005 (UTC)

I think the bud/seed split is a dubious idea, in part because the subject involves a set of techniques which do not cleanly divide. As to an article on the agriculture of industrial hemp, perhaps there is a need, but that would not affect this article. -SM 17:15, 2 November 2005 (UTC)

I think that the forum should be split between growing industrial cannabis and recreational/medicinal cannabis. Industrial should cover hemp and hempseed, while recreational/medicinal cannabis should cover marijuana. The process of growing hemp (non-psychoactive cannabis) and growing marijuana (psychoactive cannabis) are almost completely different from one anonther. Hemp is a monoecious agricultural crop grown in large fields of high to moderate plant density, and is bred for fiber or oil content. Marijuana is a dioecious horticultural crop grown extremely carefully in small outdoor plots or indoor gardens, and is bred for taste, aroma, and psychoactive content. -anon 11/5/05

---

I am going to help rework the entire Cannabis cultivation section and reduce it to as few pages as possible, possibly:

Cannabis Cultivation (marijuana)

Cannabis Cultivation (Fiber or Hemp)

Cannabis Cultivation (For Medicine [maybe subsection under marijuana])

Cannabis Cultivation (for seed)

and then, Have a General information on the Cannabis plant. Essentially the biology of the plant, it's cycles.

I know little about the production for Seed, is it really that different. My understanding is that it is rather easy, We’ll create a stub and see if someone can fill it in.

As well, I believe marijuana and medicine are separate because not only the buds are used medicinally.

What I believe is most important is that Hemp and Marijuana are separate. And that ANY growing technique for growing buds should fall under Marijuana cultivation and be on one page. I do not believe growing outdoors is different enough to warrant a separate page Harris77 21:17, 7 May 2007 (UTC)

[edit] Header image?

I have obtained permission for two images, Image:Cannabis cultivation mature two.jpg and Image:Cannabis cultivation flouro one.jpg to be released under the GFDL. The origin information is available on the image pages themselves. I am placing the mature cannabis picture at the top of the page (to replace the one that went away due to copyvio or something recently), as I think it is prettier. However, the other image, with the plants under the flouros, is more indicative of what cultivation looks like. So I'm open to anyone changing that. But the page does need an image at the top, it looks pretty dry presently. Avriette 22:07, 7 November 2005 (UTC)

Thanks for finding the pictures. The flower is the quintessence of what cannabis cultivation "looks like", so I'll weigh in on that. This flower is quite good in that spot (thanks again for restoring it). I found the young flower even more compelling. -SM 13:39, 11 November 2005 (UTC)

I was looking for a younger flower, and I too, find it more compelling for the article. However, people are not always so interested in taking pictures of the young flowers, and I don't cultivate. :) Avriette 21:21, 15 November 2005 (UTC)

How young do you need them? I cuold provide photos from seedling to 2 months young (without flowering). Freecannabis

I can provied pictures of plants at any age other than seedlings as i clone. Just tell me what you want. I also havent figured out how to post pictures, i'll work on that tonight. Harris77 22:19, 22 January 2007 (UTC)

[edit] More images

New topic, we need more images. Preferably not from the DEA— sort of growroom snuff photography, if you think about it. =(

Things that come to mind,

• better sex-identification photos
• better cloning photos, showing when, where and how to clip
• vertical and horizontal reflectors

-SM 13:39, 11 November 2005 (UTC)

[edit] Move article?

The article is almost entirely about cultivation for drug purposes (despite nods in other directions in the opening paragraphs). Most of the content should be at Cannabis (drug) cultivation. Laurel Bush 11:49, 19 December 2005 (UTC).

Don't bother. Should the seminal article on Cannabis (industrial) cultivation appear, it would be better called Hemp cultivation. Since there isn't one anyway, let's leave well enough alone.

Thanks. Very helpful. Laurel Bush 18:11, 20 December 2005 (UTC).

You know, I see a lot of very good cultivation information in hemp which could be moved here, to de-bias the article somewhat. I don't like how marijuana-focused the cultivation has become. And a lot of cultivation info is present (including processing) in the hemp article. Perhaps moving that content here would be a better solution. Avriette 09:23, 21 December 2005 (UTC)

I disagree, industrial hemp cultivation is a different endevor, and should have a separate article. What is not to like in having a first-rate marijuana-focused article. It is not bias, it is focus. -SM 19:35, 21 December 2005 (UTC)

This article is already long enough; I think that adding in hemp cultivation details would make it unnecessarily large. Having a focus is good - if someone is interested in hemp cultivation there is no reason they should be looking through cultivation for consumption. The same is true for the reverse situation. I'd say the articles should stay the way they are. Triddle 19:45, 21 December 2005 (UTC)

In that case, what's wrong with moving this to "Marijuana cultivation" and having a Cannabis cultivation page that "disambiguates" the varied desired results. Surely, the cultivation for hemp is different than for the production of oil, or silk. Additionally, this article has many mentions of other types of cultivation. It would prune the size of the article to remove all the verbiage pertaining to other motivations for cultivation. And before you question my bias, please look at my edit history on this article. Avriette 21:17, 22 December 2005 (UTC)

The debate about whether articles should be titled marijuana or cannabis has been going on for a while; I'll try my best to sum it up. The argument goes that Marijuana is a strictly American term (and is considered derogatory by some). The preferred term seems to be cannabis. The title is not that important to me but I think if this article is moved to Marijuana cultivation that it'll just wind up back here again. Triddle 21:25, 22 December 2005 (UTC)

[edit] Sinsemilla

It has been suggested that the article at Sinsemilla be merged here. There wasn't anything there that was worth merging into this article. I have changed it to a redirect. However, I dislike this solution, as I feel it merits its own article. There is, for example, a Hashish article. I think we should have a {{main}} tag in this article and link out to Sinsemilla, as we do elsewhere. The article has gotten rather ponderously large. Avriette 17:36, 11 January 2006 (UTC)

I don't agree. Sinsemilla is just a simple decision: killing or removing every male and/or hermaphrodite. Freecannabis

It means 'No seeds', it is a state of being, not a decision. HighInBC 13:55, 5 September 2006 (UTC)

[edit] Move to Wikibooks?

Since this article (and the entire cannabis resources category thing at the bottom) are more of how-tos than encyclopedia articles, I think they should be moved to wikibooks. What do you think? 67.160.30.127

I disagree. The topic itself merits an article here. The how-to nature of it is of concern, but is a byproduct of our expert contributors sharing their knowledge, but not grasping the finer points of encyclopedic tone. The current pattern of growers contributing, then editors redacting is useful and appropriate. Consigning this to Wikibooks would require a redacted version in its place (the topic itself merits an article here), which would swell again into a how-to. -SM 17:34, 28 January 2006 (UTC)

I also disagree. In addition to the howto stuff in the article (which, while not exactly encyclopedic, does cast useful information into the article), there is a lot of other information about botany and general growing. For example, while the article explains that mylar or white latex paint is necessary in getting high yields, it also explains why it is necessary. Because the article contains so much information in this fashion, I think the only way to "fix" it would be to make each subcomponent a brief mention with a {{main|foo}} link from it. That would make it very difficult to read, requiring the user to hop all over the encyclopedia to get the entire meaning. I don't have a problem with an expanded version being placed in wikibooks (hey, nothing is stopping you, be bold). However, this article is a very useful article for an encyclopedia. That having been siad, I'm 100% open as well to a peer review or a featured-article review process for this article, to get the tone more in line with what people feel is appropriate here. I am not really able to do it myself as I think I'm a bit too attached to it, and lack objective perspective. Avriette 21:17, 28 January 2006 (UTC)

I disagree as well, however I have started a wikibook entitled "Growing Medicinal and Recreational Cannabis" because I was already working on a how-to for this particular subject; I used a bunch of it for the wikipedia article (mostly lighting and atmosphere), but it is already too long for an encyclopedia article, and I am far from finished. Much of the extraneous detail from the lighting and atmosphere sections,as well as a few others, are contained in the wikibook. I think that the indoor section is too long for an encyclopedia, and if an editor were to condense at least that section, the article would be more accesible to the average reader. Also, I don't know how to link to the wikibook, so if someone else could do that, that would be sweet. -BEDN

[edit] sunlight

The sentence

When cultivated outdoors, the chosen areas are those which receive twelve hours or more of sunlight in a given day.

is puzzling: there is no place on this planet where more than twelve hours of sunlight can be expected on a random day, which is what I understand by "given". If it means "on at least some days of the year" (which makes plenty of sense, given that high latitudes are preferred) the sentence should be rephrased. —Tamfang 17:09, 17 February 2006 (UTC)

Actually, half the planet receives more than twelve hours a day at any given moment. StrangerInParadise 15:56, 28 February 2006 (UTC)

And does that contradict anything I said? —Tamfang 01:08, 2 March 2006 (UTC)

If a plant is cultivated outdoors (and it is not very near the equator) than it needs to undergo vegetative phase of growth during the summer in order to flower properly. This is not because the summer months have more than 12 hours of sunlight, so does autumn in many places. Plants cultivated outdoors do not require 12 hours of uninterrupted darkness. If they did, plants grown in northern climates would freeze before they could finish flowering (and the moon would screw them up). Among the factors that contribute to flowering outdoors are: longer nights (though not necessarily 12 hours), different light spectrum, different angle of the sun, lower average temperatures, and a greater day/night temperature difference. Incidentally, nobody actually knows exactly how reproduction is induced in Cannabis when grown outdoors. But to get back to my point, perhaps you should just say that the plant is grown in the summer and harvested in the fall to simplify things.

[edit] Spliting into new articles

This article has a massive size. I propose spliting out two articles: Cannabis indoor cultivation and Cannabis outdoor cultivation keeping both sections here as a short descriptive section and a template {{Main|location}} linking them with them. --Francisco Valverde 09:02, 13 May 2006 (UTC)

I agree with Fran, they're different subjects. Freecannabis

This article is quite long. The readable prose is currently about 60K and according to Wikipedia article size guidelines it should be split. Some suggestions about how to do that:

• This article has a Botany section that also discusses classification. These are better discussed in the genus or species articles, with summaries in this article that highlight details particular to drug cultivation.

• The article contains much detailed information about indoor cultivation. Information presented in sections 2.1 and 2.2 is not really specific to the indoor cultivation of Cannabis. Most of section 2 is applicable to Indoor gardening of any number of crops, or in some cases may be considered as a form of Closed-environment agriculture. Wikipedia is missing articles on both of those important subjects. I suggest that sections 2.1 and 2.2 be spun off as a new Indoor gardening article. Then the indoor gardening section of this article just needs to link to new article and explain any specific ways in which Cannabis differes from other plants in an indoor garden. See also orphan article at Growroom.

• There's already a detailed article at Hashish, so section 4.4 could be reduced to just summarizing a few relevant points from that article.

• Current Detection and the law section would spin off pretty cleanly with a much smaller summary section in this article.

• There are already articles at Cloning and Vegetative reproduction that cover general aspects of cloning. So again, this section could summarize the main article, provide a link, and then explain any special considerations of Vegetative reproduction that apply to Cannabis.

• There are already Hydroponics and Organic farming articles. Providing just links to the existing article on these subjects and explaining any particular ways in which Cannabis cultivation differs from cultivation of other plants in these methods would save several paragraphs.

--Chondrite 07:50, 20 October 2006 (UTC)

I'm being bold! I'm splitting them up into Outdoor/Indoor/Alternative Cannabis cultivation. [Mαc Δαvιs] (How's my driving?) ❖ 06:44, 1 April 2007 (UTC)

[edit] cultivation discussion link?

there is no link to any message board for people to discuss cannabis cultivation, would a link to, http://cannabishq.com/forum/index.php?action=collapse;c=2;sa=collapse;#2 be ok? Chq 22:45, 3 July 2006 (UTC)

well i haven't gotten any responses so i'll post it at the bottom of the list of external links if its not ok i will remove it Chq 02:34, 6 July 2006 (UTC)

[edit] HID lighting section overhauled

I revised the HID lighting section to be more technically accurate. I also removed the following statement from the discussion of HPS lighiting "and simulate a more autumn-like light spectrum"

This is often repeated, but false. The spectrum of natural sunlight does vary somewhat throughout the year, and this is more noticeable at higher latitutes then in the tropics. This occurs because the atmosphere selectively filters light, and absorbs more blue then red. Thus light that passes a longer distance through the atmosphere will appear more red than light that passes a shorter distance through the atmosphere. This can be observed every day: sunlight is more red at sunrise and sunset then at mid-day. On a seasonal basis, the angle above the horizon is closest to 90 degrees at the equinoxes, and farther from 90 degrees at the solstices. Most cannabis cultivars are short-day plants that initiate flowering in late summer, when natural sunlight is at it's most blue. After the equinox, sunlight becomes progressively less blue (and appears more red), becoming most red at the winter solstice, well after most cannabis has been harvested in the temperate regions.

The actual reason why HPS lighting enhances growth rates (at any stage) is that, for a given wattage, MH emits predomininantly blue light having fewer, more energetic photons; whereas HPS produces predominantly red light having more, less energetic photons. The quantum yield of photosynthesis is the same regardless of the "color" of the photon, so HPS emitting more photons stimulates more photosynthesis. Chondrite 23:19, 6 August 2006 (UTC)

  I need to say, that last sentence contains patently false information. The quantum yield is very different dependent upon the wavelength of light absorbed. There are two graphs which are very commonly known to biologists, one depcting the photosynthetic absorption spectrum of various plant pigments (such as chlorophyll, beta carotene, and other pigments found primarily in algae) and another depicting the photosynthetic action spectrum of a specific plant, which depicts the plant's ability to efficiently use various wavelengths of light. An example can be found on [this page] on the Maricopa Community College's website (the first result I found with google), about 40% down the page. So the quantum yield of photosynthesis is NOT the same regardless of the color of the photon, it actually depends very heavily upon the color (wavelength) of the photon. This is one of the reasons that plants do not grow well under purely green light for instance, because the quantum yield of a green photon is very little. Consider for a moment that the predominant pigment in most plants is chlorophyll A or B, a pigment which we see as green because it mostly reflects green light (up to 90%).

  The actual reason why HPS lighting enhances growth rates is that, for a given wattage, they are both: more electrically efficient than other lamps, producing more watts of light per input watts of electricity; and they are more photosynthetically efficient, with more of the emitted light being in the red-orange area of the spectrum which chlorophylls (both A and B) are more sensitive to. Furthermore, HPS lamps produce light into the far red, stimulating phytochrome, which itself is a pigment that mediates the flowering response of some plants. HPS lamps have been studied as producing up to 39% efficiency according to [this report] created by a scientist at Iwasaki (a major Japanese manufacturer of HPS lamps) in order to specifically investigate the quantum yields of various lamp technologies for the purposes of growing plants. (see [this table] as well, containing efficiency numbers)

--Jared81 21:35, 24 August 2006 (UTC)

Thanks for commenting Jared81. Unfortunately, none of your external links worked for me. Tazawa part 2 can be found at http://ss.jircas.affrc.go.jp/kankoubutsu/jarq/33-3/tazawa2/tazawa2.htm. The site TOC lists part 1, but it is not accessible.

I did not mean to imply that the action spectrum of photosynthesis can be represented as a flat line, but rather that any photon that is absorbed by the light-harvesting complex has the same net effect, regardless of wavelength. This is confirmed at the leaf level by the work of Katsumi INADA (1976), "Action spectra for photosynthesis in higher plants." Plant and Cell Physiology, 17(2), 355-365, in which it was reported that nearly identical action spectra and quantum yeild curves were obtained for 33 species of plants in response to varied spectra in the range 344–758 nm. The main difference noted was that plants that absorb a lot of green have less photosynthetic action in the UV and blue portion of the spectrum, and plants that absorb less green have more action in the UV and blue. For two lamps having the same radiant flux (in watts), one emitting mostly blue light and the other emitting mostly red light, the one producing more red light emits more total photons (produces higher photosynthetic photon flux density), and is therefore more efficient in terms of plant growth.

It should be noted that the spectral distribution of HPS light is mostly in the green-yellow portion of the spectrum rather than in the red, even for lamps marketed for horticultural applications. It is not necessarily true that HPS has higher radiant efficiency than MH (as shown in multiple tables in Tazawa part 2), and it is true that the highest PAR efficiencies currently available are MH (Hortilux Blue and SunMaster). However, increased radiant or even PAR efficiency does not necessarily translate to increased photosynthesis because quantum yield is actually a function of PPFD, not PAR watts, as explained in the previous paragraph. This is consistent with Tazawa's Plant Growth Radiant Efficiency (PGRE) ratings. The results of Ed Rosenthal that were recently alluded to in this article (without a citation) do not support the conclusion that HPS is always more efficient than MH, and in fact such a conclusion is explicitly contradicted by Tazawa's results. One limitation to Tazawa's PGRE ratings is that lamps are classified by CCT, which does not directly correspond to spectral power distribution.

Phytochromes (and other photoreceptive pigments) are involved in photomorphogenesis rather than photosynthesis. Certainly this plays an important role in the flowering response (e.g., the induction of flowering in response to short day photoperiods) but not for the reason given in the statement that I removed from the article. Additionally, the phytochrome-mediated low-fluence responses have very low activation and saturation energies, and are sensitive to light spectrum but not light intensity. Phytochrome A and other pigments are involved in the high irradiance responses, that are sensitive to light intensity but relatively insensitive to spectrum. So the increased (relative to MH) output of HPS in the red portion of the spectrum is not particularly important to photomorphogenic responses. See http://www.jbc.org/cgi/content/full/276/15/11453 for more information. Chondrite 20:44, 6 September 2006 (UTC)

[edit] Merging Marijuana grow operation here

Marijuana grow operation completely overlaps the content of this article and is mostly redundant. I suggest the any valid content from Marijuana grow operation be moved here and then it be turned into a redirect. HighInBC 13:51, 5 September 2006 (UTC)

The person that wrote this article must have spent many hours of labor and love doing so, it should be left well alone as it's proficient in what it is trying to convey and rarely 'muddles the picture', so what if it deals with more than one 'topic', they're all interwoven and (it)provides quick and easy access to those that wish to delve further. To split this article or merge it with others would significantly distract from the main theme(s) —The preceding unsigned comment was added by Aribritt (talk • contribs)

I agree that it should be merged. It makes sense for them to be in the same article, considering how closely related the subjects are. If the article grows beyond a reasonable size it could be split off again though. Harley peters 20:21, 2 October 2006 (UTC)

Done. HighInBC 21:52, 2 October 2006 (UTC)

why no pics of a fully grown plant?

This article could even be deleted... 66.246.72.108

Thaks for the tip, we are probably going to keep it unless you have some sort of... reason for deleting it. HighInBC 13:45, 19 October 2006 (UTC)

[edit] drying, curing

I'm going to try to dry it out (no pun intended-no, really) so it's a bit more...encyclopediac. I will not change any content without a consensus here first. Resonanteye

Ok. Finished my first easy scan-through and what I see is: an exhaustive list of lighting, watering, and pruning techniques which are ireelevant to an encyclopedia entry on this plant and its cultivation. This could be pared down to a few paragraphs explaining and listing, rather than reviewing and criticizing and joking about various methods.

This style applies to almost every subject in the article. I dislike paring anything too heavily for content, but this actually may demand it. Does some green thumbed genius want to maybe make a whole new page about what lights are good, what fertilizers, etc, for indoor cultivation techniques?

I don't want toi really remove content but I am going to make a fat shift in things and try to organize a bit more neatly, so that it reads less how-to and more "this is what"

If anything seems to extreme or wrong, or loses necessary content, by all means revert or fix it.

Lots of POV and original research in this one too. But that is someone else's problem. Hope it helps Resonanteye 12:29, 21 November 2006 (UTC)

Ok. This page is about the cultivation of cannabis, not light biulbs and fans and what they are called and how they work, I think. So I did a major edit. If it's too much, fix or revert it and let me know. I got to the outdoor section and had to quit, technical issues. Resonanteye

I'm back for another run at it. Once again,I'll "watch" for changes, but if you have any feedback on how I'm editing please leave me a note on my usertalk page. Resonanteye

I got all the way from "outdoor" to "mother plants" before I had to go do something else. It's almost like reading about chocolate. Except it's written like a how-to. I hope my edits are helping. This article needs a ton more sources cited, though, and I can't do that... Resonanteye 08:27, 27 November 2006 (UTC)

[edit] LED Lighting

wrongly says in the text that relatively inexpensive arrays are available. I have a gut feeling that there is a large amount of hype in manufacturers' claims (even more than with the 125 and 200 watt fluorescents that are now available) —Preceding unsigned comment added by 195.188.152.14 (talk • contribs) 11:03, December 4, 2006

I saw an unsourced statement regarding LEDs, I have put a citation needed on it. I don't see any references to price, can you quote the text? HighInBC ^{(Need help? Ask me)} 19:22, 4 December 2006 (UTC)

"Recent advancements in LEDs have allowed for the production of relatively cheap, bright and long lasting grow lights that emit only the colors of light required for plant growth. These lights are attractive to indoor-growers since they do not consume as much power, do not require ballasts, and produce a fraction of the heat of HID lamps.The lamps consist of arrays of many wide-spectrum red and a few narrow-spectrum blue LEDs of specific wavelengths."

"Although LED grow lights have shown promise through plant research by NASA and many universities, it is unknown whether the results are applicable to Cannabis cultivation."

Further to my previous comment, I don't think the NASA comment justifies the previous text - which may well have been placed there by someone with commercial motivation. The "heat" reference is patently counter to the laws of physics (captain). —Preceding unsigned comment added by 82.32.18.123 (talk • contribs) 19:13, December 5, 2006

Currently there are experiments by growers using LED lights, i will update the page once they are done their grows. Harris77 22:08, 22 January 2007 (UTC)

[edit] Wikibooks, again

• • • I am not proposing to move this article, I think it is coming along fine the way it is.

However there is a vast quantity of information being posted here, much of which is getting trimmed away in order to be an appropriate size for wikipedia. But on wikibooks this information could be compiled into a much more complete "how-to" sort of book. But is this possible?

I noticed from this talk page that it was attempted before in the wikibook "Growing Medicinal and Recreational Cannabis". I am not sure on wikibook policy for a topic like this (I've looked, havn't found). The information itself is not illegal, however actually carrying out the instructions in the book would be illegal, in the US at least. What is wikibooks policy on this sort of thing? (I dont know my way around over there, which is why I am asking here). The article I mentioned was speedily deleted as can be seen here: http://en.wikibooks.org/wiki/Wikibooks:Votes_for_deletion/Archive_8#Growing_Medicinal_and_Recreational_Cannabis

It should be noted that it was deleted by a single user who simply stated "this is not material similar to that used in textbooks in accredited learning institutions". Which I rather doubt is official wikibook policy, as there are few accredited learning institutions which teach Lucid Dreaming, Overcoming Procrastination, Character creation ans Shaving. This user went against the community consensus, which was neutral and in favour of merging it with another book (pointing out that it was well written in textbook style).

So, to summarize: Would a how-to on growing cannibis be against wikibooks guidlines, or are there any other reasons why it could not be done?

Would anyone else be interested in this? I've barely looked at wikibooks before this issue, so I do not know how things are done there. But if someone (or me if I had to) were to create such a book, I would certainly be willing to add to it, move information from wikipedia and other sources, and in general attempt to make it as formal as possible. Would others help?

Just to be clear on this, I know this was attempted before, and deleted. I disagree with this, as the deletetion was due to a single user acting against community consensus. I think it should be revisited unless it is explicitly against standing wikibooks policy.

[edit] Accuracy (or otherwise) of European "law on possesion map"

Cannabis has NOT been "decriminalised" in the United kingdom. The penelties were recently reduced (reclassification to Class C) and SOME regional police forces have adopted a policy of not prosecuting those found with small amounts for personal use but this falls well short of "decriminalisation". In the Republic of Ireland the law is DEFINITELY still enforced although perhaps more vigorously in some parts of the country than others. —The preceding unsigned comment was added by 87.113.14.139 (talk) 16:00, 2 February 2007 (UTC).

[edit] Confused

The existence of three different articles (Cannabis (drug) cultivation, Indoor Cannabis cultivation and Outdoor Cannabis cultivation) seems confusing to me since much of the information is relevant to each article, but is not presented in each.

For example, the topic of Process is specific right now only to the "Outdoor" article, but processing applies equally to indoor cultivation. Should Indoor and Outdoor be combined or should processing be a separate article?

Also, topics covered in the "Indoor" article (Germination, Seedling Phase of Growth, Vegetative Phase of Growth, Reproductive/Flowering Phase of Growth) are equally relevant to growing outdoors, but are not mentioned in the "Outdoor" article.

Another item to note is that in the "Indoor" article, the topic of "seedling phase of growth" is covered, but not the phase of growth of clones. Clones are covered in this article (Cannabis (drug) cultivation).

What would be the appropriate action(s) to take to have the information be presented in an all encompassing manner? My thought is that all information should be merged and edited into one article titled Cannabis Cultivation.

I see from other discussion notes that some feel separate articles are necessary. If that is a majority opinion, my 2nd thought is to pull out information that exists in just one or two articles, but is relevant to all, making them separate articles (examples: Cannabis Cultivation: Phases of growth; Cannabis Cultivation: Harvesting, Drying and Curing; Cannabis Cultivation: Detection and the law; etc.).

If a decision can be achieved, I would volunteer to take a first crack at combining the information or breaking it down even farther into more articles. I would only ask for some direction and proof readers. Thanks for considering! _{--Big.thompson 16:59, 7 May 2007 (UTC)}

My personal opinion is that there should be 1 large article encompassing everything involving the production of cannabis Buds aka marijuana.

I believe the only other article could be growing for Help fiber production, as it is very very different.

This is because there are lots of different growing methods Indoor, outdoor, LST, FIM, SOG, ScreenOG… Why would we have different articles when these are just different perspectives on the same thing… producing buds.

As well 90% of growing is about the plant not the technique. I think the page should have a lot of general knowledge on cannabis then small sections outlining the specific info on, for example, Outdoor growing. There are some differences but not many

PS—I would also like the title of this article changed so that Cannabis is not referred to as a “Drug”. It’s just negative diction, cant we just say Sinsemilla cannabis production Or Just something more non-partisan. As calling it a ‘drug” automatically classes it with Cocaine, heroine LST E and so on (I’ll think on this)

I don’t have time right now, but ill help you organize the cannabis section if our goal is to reduce the amount of pages. I’ll check things out Harris77 18:52, 7 May 2007 (UTC)

After some thought I think that we should have 3 pages:

Cannabis- For medical use

Cannabis (marijuana)- for the “drug”

Cannabis (hemp)- for the fiber

These are IMO the three proper distinctions. But should we divide up cultivation into these three sections? I believe no and that only two (marijuana and hemp) are necessary. As well, most people care about marijuana cultivation not hemp (hemp'll probaly be a stub)

Do you think we should clean up this discussion page so that it is more productive?Harris77 21:01, 7 May 2007 (UTC)

[edit] cannabis is illegal

this article is just a guide to growing illegal drugs. it has no place here. —Preceding unsigned comment added by 80.86.74.135 (talk) 00:40, 8 September 2007 (UTC)

I dont agree. Its not a how-to-do-it article, which would be unacceptable. It deals with the subject in an encyclopedic manner. Wikipedia neither supports nor opposes cannabis cultivation or use, it presents the arguments of both sides. Feel free to edit to make the article better, SqueakBox 00:47, 8 September 2007 (UTC)

So why does does cannabis deserve a page on its cultivation and not all the millions of other species that exist? —Preceding unsigned comment added by 80.86.74.135 (talk) 00:11, 12 September 2007 (UTC)

Simple really, there is a demand for the article. The fact that cultivating cannabis is illegal does not change that. Dan Bower 00:51, 1 November 2007 (UTC)

It bears mentioning that cannabis cultivation in not illegal worldwide, nor throughout the U.S. Several U.S. states have enacted medical marijuana laws, making it legal for licensed users and/or growers to cultivate enough for their own or their patients' use.

The original author of this article (me) had a huge jihad with squeakbox about that very subject. He's certainly more motivated to keep that text out than I was to keep it in. Note this is a shared IP; not everyone editing from "here" is me. 206.230.62.2 (talk) 19:33, 15 April 2008 (UTC)

[edit] Grow-op

The term grow-op was new to me so I looked it up on Wikipedia. It actually redirects to this article but nowhere is the term mentioned. I'd like it if the article told me about some terms like these, how old they are, how established, whether they are slang or not, which countries they're used in. I've never heard it in Australia but came across it in the context of a novel by a Canadian author. — Hippietrail (talk) 22:32, 10 June 2008 (UTC)
