How to Grow your Cannabis PURPLE!

How to grow purple cannabis

Did you know that many roses that have extremely vibrant colours aren’t naturally that colour? No. They put dye in the water and the petals, that would originally have been white, or red, absorb the dye in the water.

However, you don’t have to use purple dye in the water for your cannabis plants as you can actually buy plants that produce purple cannabis – more on that later

But first lets explode a few more myths.

Depriving your plants of oxygen, or any other gases for that matter, won’t turn them purple, but will be more likely to kill them.

Feeding your plant excess nitrogen won’t make them turn purple either, though it will likely change their colour to brown as they die and wither after getting burnt to a crisp.

You could try purple dye, but we don’t recommend it. If you do go down that route for fun, get a natural food colouring, not a chemical dye, as you are going to be igniting and inhaling the dye at the end of the day.

As for which parts of your plant will turn purple, this can be the pistils, the calyxes, the leaves and the trichomes.

Having chosen the right plants, there are still a few things you need to keep an eye on.
First, once they have ended vegetative growth and are ready to start flowering, drop the night-time temperature by 10-15 degrees compared to the daytime temperature.

This will help break down the chlorophyll and encourage the production of more anthocyanins.

When it comes to naturally purple plants, keep an eye out for Purplematic CBD ,Purple Queen, purple punch, granddaddy purple etc – the names should give you a clue.

Purplematic is high in cannabidiol and very low in THC, with deep, rich purple buds.

Purple Queen is virtually a pure Indica and a combination of Hindu Kush and Purple Afghani genetics. Flowers after roughly 10 weeks and has a high 22% THC content.

Blue Mystic is a cross between Oregon Blueberry and Northern light, resulting in an 18% THC level and rich, purple buds.

I wonder how Purple Ronnie got his name…

    I’m just starting a Purple strain shout out to Nukeheads. I was wondering what is the best way to feed it. I’m also growing 2 chocolopes from Ilgm, which are mostly Sativas.

    Is it dangerous to drop the Temperatur from 25 to 15 degress ? Is there a chnace some flowers will die ?



  19. @austinprunty8167 on May 7, 2024 at 11:47 am

    I wonder if mulching purple potatoes in the soil would help. Potatoes do have good veg nutrition



  20. @bensonbright on May 7, 2024 at 11:47 am

    Cold or ice water on the roots in the last three weeks will enhance the purple colours apparently .



  21. @CactusCowboy57 on May 7, 2024 at 11:48 am

    About 50% of my Agent Orange plants have purple buds. Afghani leaves will turn purple with colder temperatures. My outdoor plants were subjected to frost (27F) last night. Four hours later no serious damage but there was an increase in purple leaves



  22. @Sylvester4571 on May 7, 2024 at 11:50 am

    3 ways to make your weed purple:

    1 – Colder temp at night like the video explained

    2 – Genetics

    3 – Starving the plant of phosphorus. I have seen a couple of growers do this outside during warm months and the plants did in fact turn purple.



  23. @user-vi9ql1nc9m on May 7, 2024 at 11:51 am

    I have to make a purple and very high thc strain and I will call it Thanos or something like that 😂



  24. @lucajinn8589 on May 7, 2024 at 11:51 am

    I grow watermelon auto, but I don’t see any purple at all. Now it’s the flowering phase but it’s still green



  25. @sammicoporsammicopor on May 7, 2024 at 11:52 am

    I have noticed that purple buds tend to be more indica or berry flavored.



  26. @officialtheory001 on May 7, 2024 at 11:53 am

    One of my bc god bud plants turned purple and had a grape gum smell a light purple though not dark even the trichomes went purple

    Love all the great tips…😒



  30. @GMT439 on May 7, 2024 at 11:56 am

    Do not add any colourings to your plants.



  31. @davidbrandenburg8029 on May 7, 2024 at 11:58 am

    this video didn’t say anything about growing purple varieties!



  32. @Caseyuptobat on May 7, 2024 at 12:01 pm

    Calyx. Not Calliexes. Please learn to speak English, Englishman.



  33. @michaelfeehily5926 on May 7, 2024 at 12:01 pm

    Black Sirus Is Blackish weed and will knock you out over 35 % thc and its 100% Indica.



  34. @eddiesland93 on May 7, 2024 at 12:02 pm

    Any plant turns purple in the cold.👍🏻



  35. @MagikFingers420 on May 7, 2024 at 12:04 pm

    Havent grown any purp, but smoked it and it also gets you high, nothing new really.



  36. @baymaster20 on May 7, 2024 at 12:05 pm

    Purple buds are bad from the plant turning purple because of how hot it gets so it changes colors some people say it’s the cold most Indica are all purple like granddaddy purple and people have use the genetics to cross them and create these hybrids that now have more Indica dominate genetics which will turn it more purple🔥



  37. @billmattulke1240 on May 7, 2024 at 12:07 pm

    Lies



  38. @dipzo1612 on May 7, 2024 at 12:11 pm

    ❤what is the best to grow outdoor



  39. @StanwoodSpartans on May 7, 2024 at 12:12 pm

    I’ve seen purple bud, but this blue bud I saw was beautiful.

    Absolutely reaked of fruity skunk. Had to use 2 jars to contain the smell.



  40. @user-zl1pj5ii1f on May 7, 2024 at 12:12 pm

    There are roses that are naturally purple though lol or (hybrids) that grow purple and not altering it with food dye



  41. @Quigonjinn_ on May 7, 2024 at 12:13 pm

    if your plant does start turning purple outdoor late in the fall like late october early november chop it the purple leaves will do fine in the cold the green leaves will mold out in the cold.



  42. @roobotix on May 7, 2024 at 12:18 pm

    Here’s an idea grow outside.



  43. @kiyomiheinrich2147 on May 7, 2024 at 12:19 pm

    changing the temp, may slow T.H.C. production…. instead learn to breed, and pheno hunt…its a blast!

  45. @zanetorres1291 on May 7, 2024 at 12:22 pm

    Cannabis turns purple when cold and stressed. Don’t dye your cannabis.

  47. @GenXRedneck420 on May 7, 2024 at 12:23 pm

    Well back before all these new growing techniques… We just used to grow purple Haze to get purple weed. Lol 🤣🤣🤣



  48. @buddydavidson8549 on May 7, 2024 at 12:24 pm

    But what strains are guaranteed to turn purple what strands of Potter guaranteed to have the genetics that cause it to turn purple



  49. @psyience3213 on May 7, 2024 at 12:25 pm

    This seems correct. Biggest factor beyond genetics ofc is going to be temps. My grow tent gets down to like 59F from about 75F during the light cycle. I’ve noticed nice bluing/purpling as soon as it hit the budding stage (with this indoor grow). Last outdoor grow it was the same, the purpling started in September/October when we would get some decently low night time temps.
