    So I see a lot on-line where people often recommend to use cold temps to get buds to turn purple, but I have also recently learned that stressing a plant, especially a strain known to turn purple will do a nice job too. Specifically, things a little higher on the high stress training side of things, like pinching a branch down early flower. To me this seems a lot less harmful than colder temps at night and was glad I found it to work...

    I've also seen them go purple when they are seeded up, and also not from seed, but then a clone will do it.

    Anything else you guys have seen that works to bring out the colors?

    Different phos. Levels will bring out different colors. Black lights will also do it.

    The more stress that you cause your plants the more likely they are to herm.

    Cold temps at late stage flowering will do it .
    Drop day temps a bit
    night in low - mid 60s .

    One way ive read about is to drop the temp of your space down by 15-20F during your night cycle in 2nd half of flower.

    20f will kill a plant.

    not meaning turning your room into a freezer.
    like from 75F drop it to 55-60F at night. Which is not at all an uncommon drop outside.
    Like I said though, its just stuff Ive read about. Not sure of the accuracy of the drop needed.

    Ahh...you mean drop the temps 20 degrees....not make the ambient temp 20F. Haha...that makes much more sense ;)

    I mean, if someone was able to maintain 20F in a grow tent right now id actually be pretty impressed. LOL!
    But edited the post for clarity.

    I have some bagseeds of a really nice grape strain we got once I cant remember what it was, but it was damn good.
    I had 4 of them I seeded, they were the fastest seeds to germ and sprout and all 4 are by far the strongest looking of the bunch so far.
    As far as I know, most of what we got around then came from the same grower so it should have strong genetics. If they go well i'll be perpetually cloning them for sure.
    Ive read into this because im hoping to be able to grow some nice purple stuff too!.

    Find a good stable pheno that does it naturally and clone. I grow a bit of purples natural is better than stressing it to turn purple.

    Yeah, to be clear here, turning purple is nearly all genetics. You cant force a plant to turn purple that isnt supposed to be purple. Any method is just a way of maximizing the color the plant already has.

    And a 20 degree swing from day to night is a pretty natural outdoor occurrence. We have a 15-20F drop from day to night right now and there are plenty of ppl growing outdoors here.

    Two nights of 16F will kill a bunch of them. Don't ask how I know.

    Cold will help with purpling, but nothing beats good genetics.

    I lost a whole bunch of peppers like that a few years ago. Few plants each of habanero, jalapeno, cayenne, and bell. We had some freak cold front really early in the year and they all froze to death.

    I lost my spring crop this year {here in NW Florida}. I forget how many I had of what strains, but we had a week in the 20's then two nights of 16F. The year before the low had been 25F. It burned a few buds, but didn't kill anything. I have a strain called Gorille de Raisin {Grapish X Donkey Kong} that gets really purple from the frosts. It has just a tint of purple when flowered in the fall.
