What Makes Some Marijuana Strains Turn Purple?

purple urkle marijuana strainI will never forget the first time I saw purple marijuana. A girl I used to hangout with when I was a teenager told me that she had some Purple Kush, and that I had to smoke it with her. She kept it in a non-see-through jar, and I vividly remember when she pulled out a nug, my mind was blown. I had never seen purple marijuana prior to that, and to be honest, I was skeptical that it would actually be purple until I seen it. But sure enough, the nug was dark purple, smelled like a Cypress Hill concert, and was sparkling with trichome glory.

Purple marijuana strains are highly desirable in my circle of friends. I get asked all the time if I know where to find purple marijuana, and I also get asked all the time what makes the marijuana purple. Below is a good explanation from our friends at Sensi Seeds:

For many years, the only purple varieties of cannabis were those that had been grown outdoors and subjected to cold conditions. Many strains of cannabis purple to some extent when exposed to cold; now, selective breeding programs have yielded cannabis genetics that are purple even in normal environmental conditions.

Anthocyanins are a group of around 400 water-soluble pigment molecules that due to their structure and biosynthesis are classed as flavonoids, and appear red, purple or blue according to their pH (in acidic pH levels they appear more red, in neutral conditions purple, and in alkaline more blue). Flavonoids are generally yellow in appearance, hence their name, which is etymologically derived from the Latin for “yellow”, flavus, and does not indicate any association with flavour. In fact, flavonoids are usually extremely bitter, and are generally associated with pigmentation.

Next time you are smoking a purple strain with a friend, feel free to explain to them why the marijuana is purple. You will look like a marijuana expert!

    “…selective breeding programs have yielded cannabis genetics that are purple even in normal environmental conditions.”

    At what cost? Has purple bud lost some strength in the process?

  • Johnny Bloomington

    Looks cool but is it just over hyped?

    • AnthroGrow

      Well, there is a lot of hype right now for “purple” Cannabis, due in some part to media / rap music, and because it’s the cool new thing. The bottom line is genetics + environment. Most “purple” genetics has been just about stabilized enough that with the right environment (like cold and ph) it will produce Grade A medical Cannabis. It’s a nice fun variety to have :) but it can just as easily be grown poorly and just be bad purple regs. One cool thing about Cannabis, it’s definitely not boring lol! As soon as we get one new thing stabilized, another wow fun new thing pops up. I’ve been watching closely as some breeding companies are working on Black and Red strains!

        From what I have found the purple color while caused by low temps can also be forced from a great deal of indica strains by lowering Phosphorus intake in the last few weeks of flowering and it will cause a colour change towards purple.

    Back in the 70’s I lived in Hawaii and had bought a pound of really good Columbian. I took the seeds and when I planted them, 1 in every 5 came up purple. Purple buds, some purple leaves and purple streaks up the stem. I took seeds from THOSE plants and ALL the second generation plants were purple buds ! The shit was absolutely paralytic… Take ONE hit off the joint and 20 minutes later you look down at this joint that went out in your hand and say “Huh ? What happened ?” . I thought “Now THIS stuff will be HUGE someday when it’s finally legal !”. Absolutely scary gorgeous and stoney as hell ! Problem is, I got SO STONED I lost all the seeds ! SHIT !

    I grew some Holly Grail Kush and half the plants came out with purple leaves and purple buds.

      You know you are an intelligent person if you can engage in such horticulture as is required to grow these plants, sex them, clone them and so on, then you’re intelligent enough to spell “Holy” correctly. Yes, it does matter and no, it’s not picky: it’s communication which is the only means humans have to connect, not to mention the importance of representing this industry as a person of reasonable intelligence. Represent: if you have a company, put on a stylish shirt and a loosened tie at company events and for photos; spell words right; show intelligence and draw the “not so normies” into becoming investors; small concessions to garner success. It’s no wonder Greenbusinesses can’t maintain reasonable stock prices and capital when we look and act like schlubs who couldn’t care less.

      • Pipeweed

        The dude misspelled one word. No need to go on a rant.

        • Ooh-Bigtime

          Yes, there IS a need to go on a rant: “Mary Jane” companies have investors who put some or all of their life savings into these peoples’ companies, that’s a lot of people relying upon a CEO who won’t put on a tie and compete in the “business” to win success for his company and therefore his benefactors/shareholders. The “rant” was more about the terrible showing of certain CEOs at events that would legitimize the companies they represent as well as the weed legalization movement as a whole. Time to put on your “Big-Boy Panties” and be the change, or shut the f88k up and step back, give back peoples’ investments back to them before you wreck their lives.

          • Trish

            ” give back peoples’ investments back to them before you wreck their lives.” … Is this proper English? You are ranting and you are far from perfect, as we all are! There are MANY “types” of human beings who represent the cannabis industry so do not stereotype or judge based on YOUR perception! One misspelling does NOT mean a person is unable to communicate effectively. Jeez Ooh-Bigtime, loosen up a little and have some fun once in awhile! :) Peace!

            no you need to shut the f**k up, who are you to cry about someones spelling, and telling someone to “shut the f88k up and step back, give back peoples’ investments back to them before you wreck their lives” is pointless from a no-body who wishes they were in the business, its not “mature” of you either, sadly you seem stuck in the closed minded circle of “weedhead wannabe smartasses” that is too busy harassing other people over what they are spelling/doing wrong to focus on your own flaws..

          • irememberallthelies

            I misspell stuff all the time due to my phone lagging or messing up. Then when the comments are laggy its near impossible to go back and change it sadly. Its a comments section, not a business proposal I assume

          • Ooh-Bigtime

            Point taken, I hope mine wasn’t lost.

          • Ag Ponzio

            Damn, if the high makes me like this guy some time, please kill me.

          • Ooh-Bigtime

            It’s more likely “the high” will make you so apathetic that you’ll write stupid comments like that one instead of being intelligent enough to see that I’m right. This issue is a political one, that matters. If people are to gain legitimacy for their companies and change onerous laws like America has on the books right now about weed, it won’t be done through hippies in tie-dye showing up to company meetings smelling like B.O. and cat piss, it’ll be done by people who make an effort. That includes being literate and wearing clothes that are clean, having real accountants, investing and lobbying lawmakers. It takes serious, credible people to get Federal laws changed.

          • Ag Ponzio

            Misspeling holiday on a comment in a forum doesnt make you iliterate.. You don’t even know if this guy’s main language is english, so please, stop thinking you’re intelligent and shut the fuck up, you’ll seem way more intelligent that way.

          • Ooh-Bigtime

            I don’t think I’m intelligent, I think I, though no more intelligent than any other person, at least know that impressions of people are “true” whether or not they are actually fact, so any person who doesn’t understand that is below grammar school and unqualified to lead a company and I am RIGHT. Not being able to spell Illiterate DOES MAKE YOU illiterate so why don’t you shut the fuck up, go back to grammar school …..no wait: you know what? stay stupid, people need to be able to identify types like you.

          • Ag Ponzio

            Running a company? I think your super intelligence and literacy are making you just plain stupid. And btw, not being able to spell illiterate definitely doesn’t make anyone illiterate, you can check for the definition of illiterate online, I’m sure even you with all your cognitive problems might be able to figure that out :)

          • Ooh-Bigtime

            stay stupid bro, stay stupid. ;-)

          • Ag Ponzio

            Your only argument is invalid? Don’t worry you’ll be fine.

          • Ooh-Bigtime

            You’re an illegitimate peasant slinging bags on a corner like a petty criminal if you don’t understand why the marijuana industry needs legitimacy and your parents are illegal so you don’t care that it’s still a federal crime technically to be in the industry? Don’t worry you’ll be fine. Or not.

          • Ag Ponzio

            You keep talking about other stuff that was never in discussion. You’re cunt that started talking shit about a guy misspelling one word because he’s on a shitty tablet. That’s the only thing “in discussion” here. It’s not even debatable, you’re a cunt, end of story. Now take all your business and nonsense talking somewhere else.

          • Ooh-Bigtime

            Ag ponzio, the fact that you are too stupid to see the relation of one thing to another is not my problem, the fact that you are too stupid to see the value of grammar is also not my problem, you are stupid, so you will naturally have those problems. Is he on a “shitty tablet”? How do you know that? If you do know it, did you know that reading is also an option? YES: ACTUALLY READ what you’ve written, it’s an ancient concept and since you’re too stupid to relate one thing to another I see I have to tell you about it really slowly and specifically for you to get it, so I’m being very generous to do that for you. You’re welcome. (not YOUR welcome, that’s improper use). The fact that your parents are illegal and therefore you have no problem with the industry being illegal is a call to your state of mind thinking it’s okay to be a criminal against federal law, and just feel casually about it, do you see how those things are related? NO? Okay, well most people who break federal law crossing a border illegally are also willing to commit other federal crimes if they get by with that one, it’s called a “mindset”, look it up if you need the definition. Do you know how to look up words in an Encyclopedia? Often and encyclopedia will give a deeper definition of a word than will a dictionary, so I recommend you ask your homeroom teacher how to find an “encyclopedia” (ehn-SY-clo-pee-dee-uh), not to be confused with “Wikipedia”, a website that can be edited by users. Now go do your homework and then I’ll get back with you after your next ridiculous, cunty post. THANKS! :-)

          • Ag Ponzio

            Are you aware of yourself? I mean, you can’t be that stupid for real. You just wrote the longest sensless comment I’ve ever had the change to read. It’s people like you that fuck up the world, you can’t just use your head. It’s sad.

          • Ooh-Bigtime

            Does that upset you, that I’d do that? Don’t be mad.

          • Ag Ponzio

            Why would that upset you? At most I’d feel a bit sad for arguing with a retarded troll.

          • Ooh-Bigtime

            I do feel sad that I’m arguing with a retarded troll. :-/ *-]

          • Ag Ponzio

            Lol you needed to edit that?

          • Ag Ponzio

            You can’t even spell what you’re supposed to be standing for. That’s just floor level pathetic. You don’t get down from there. See ya buddy, be good.

          • Ag Ponzio

            by the way, I know he was on a “shitty tablet” because that’s what he said. I don’t understand the whole “illegal parents” thing you’re saying, what makes your comment long, boring and stupid. You still haven’t even connected the typo the guy accidentaly had with business, marihuana, and illegal parents.

          • Ooh-Bigtime

            Hey: last word queen: did you read my first post outlining my entire point which was the marijuana BUSINESS? Did you know that selling weed if not a co-op (business) or a grow operation (ALSO a business) is a Federal Criminal Offense in America? You must be content as a clam at being a petty dope slinging peasant, but most normal people want the industry (BUSINESS) to gain legitimacy and legality as is so in Britain. You go ahead and continue being a dumb peasant slinging bags to buy Nikes, STAY STUPID BRO, STAY STUPID. ;-)

          • Wtf

            Maybe you should learn to capitalize ?

  • Bill Landreth

    I was told the plant was running low on nitrogen, so it turned purple. Also many a time I have seen dyed purple buds. But as far as smoking purple I found it registers much faster than good THC ( “ooh yeah I’m high!” ) but is super stressy. Good thing it lasts (the stress) like a day and not a lifetime as in cigarettes. Of course am only a person am certainly not all right, if at all.

    Which brings me to my next comment… wow I am human and I speak a human language (thank mankind) and I am really annoyed at foreign types who would speak against Shakspear for making up words and spellings. If someone (I am on this tablet keyboard) doesn’t quite line up with things as you and webster have it, GET OVER IT and be glad we are even on the same alphabet! English has no matematics it is wholely human and holy or not depends on the listeners ability to get something out of it. Thanx.

    In my experience…. purple came from a hermy plant. It was a delicious hermy plant once the seeds were sifted out. But that’s not why it purp’ed. I have found that a method to purp was to starve the plant in its final weeks. I would grow less in the veg stage and feed it it a fert that was low in N, but high in P and Ph. This causes it to use a great amount of potasium that it had stored, and when it gets drained it changes to a purplish color inside the buds when you break it open. Its basically like an indicator that it needs nutrients, but you want to starve it and flush in the last couple weeks to get good results… or so I found…. others may disagree.

    My god, that method produced the most delicious weed I’ve ever smoked… so I really didnt care that it hermied… I cloned the shit out of it, and smoked it all! so good….. it came from a bag seed… some kind of kush that was not nearly as good as after I had grown it. all gone now…… shooulda kept some hermy seeds…. or maybe I did??? hmm……

    • pdderek

      Well, from what I understand both hermaphroditization (if I may use the term!?) and purpling of the flowers occur due to the same conditions: COLD! And stress in general. But the stress is likely the cold in these instances.

  • ddddddddddd

    My experiences put aside, I remember the first time I smoked purple weed. It was me and my friend. I just copped a eighth and when I opened the bag, it reeked. I once left half an ounce in my jeans with my dads laundry and the clothes smelled “herbal fresh” after but the way purple made me feel that ass whooping didn’t hurt a bit.
