I can’t help but feel like @Bobgrows is missing from this Convo, she loves her purple plants
Also surprised the purple paonia paralyzer from @DougDawson wasn’t mentioned cuz I’ve seen the seed pods on other plants go purple from its dustings. Heavy purple lingers on those genetics for sure
For autos the blackstrap that @hollyho passed around was consistently dark ass purple too
That I do! 1) they are just pretty 2) some have the fruity flavors-terps I like or the coffee phenos like Pre 98 Bubba Kush.
This one was one of my favorites!!
Congo Sherbert…
@AzSeaindooin420 I think we’ve talked too much… lol I forget you know alot about me! 🫣 
Talked to much? Never such a thing with the grow fam!
bodhis purple unicorn is 100 percent purple. i grew out some purple unicorn F5s and the potency was non-existant. never again.
Consider what you want. This post is not meant as a thorn in your eye, but as a possibility-expanding suggestion.
You will never get to 100% because it’s not possible, and here’s why: evolution.
The 1 constant in the universe, is CHANGE.
Genetics are nothing more than a juggling of balances between traits that get passed on or not, and are turned on or not.
IF YOU SUCCEED at producing a strain that, in your setting, produces 100% purple plants, what is going to happen when you distribute it, and other people will grow it out, well, one of those people will have either different enough circumstances that the plant, especially over several generations, will come out differen, OR, once upon a time there will be a genetic freak of nature as all strains put out, and a seed will pop that decided it wanted to live a green life.
That’s not a bad thing at all.
You don’t have to do it at all, but I would like to advise you to roll with the punches of growing and not become held back by percentages and things that don’t turn purple.
There are different ways of becoming purple. As has been said, some plants even turn the trichs purple, I’ve seen it under my own microscope from my own grown and have squished out purple resin from rather fresh plant material (only way to push out purple resin seems to be using fresh cause the coloring tends to become unextractable once the pH changes happen that happen in buds and leaves when they are drying).
But the fan leaves could turn purple leaving all the buds green. That plant may turn purple 100% of the time but not a person in the world smoking the buds will know or see it cause only the fan leaves turned. It can also happen that only the individual flowers will turn purple, or only some of them.
So if we assume that all of those are directed by different genetics or epigenetics, then it’s safe to assume that it’s influencable.
If it is influencable, like with temp fluctuations, there’s more to it than just going “These always go 100% purple”, because there’s always more situations to try out.
I applaud the effort but at the same time I don’t believe you or anyone else will ever get there.
But I won’t say it’s impossible to create a strain that puts out near 100% purple-inducing individuals from seed. I think it IS possible. But it’s the NEAR that makes it possible.
If you are not willing to select out the “good” from the “bad”, why grow at all?
B-E-A-UTIFUL!
There once was a strain called Mata Hari that would color into a rainbow array near end of flowering. Reminds me of her.
Relentless genetics specializes in making purple/red weed.
Todd Mcormick sells purple NL5 (NL2?) Out of his outlet, Authentic genetics seed co.
Purple Mexican Heirloom - IBL from Kropduster is supposed to be purple to black all the time.

Gooey breeder is the man for all things purple n gooey sum of the best flavours in any weed from his old purple mayhem his black raptor looks fire too
I’m running Purple Urkle, Grand Daddy Purple and Purple Kush looking for sedative strains. I’ve also got Romulan vegging but I don’t know if it turns purple.
Most purple strains I’ve smoked have that signature taste an I just can’t get past it lmao, too nasty for me.
Romulian should of it depletes the nutes and cooler weather she should purple up.
these were my best purples.
Fruitz …id grow it again. really nice. i have 2 fem seeds left
i was just having fun that grow. as always.
love the contrast in colours
I’m grinning while posting this, just KNOWING how much yall will appreciate it… A sorta friend, found it in my seed. I reversed the top and procured pollen. The bottom is in ruff shape with a handfull of selfed seed. This pic is the prettiest she ever looked. twas down hill from here. lol.
was found by numbers. Friends grow, could have went better, especially in the beginning, but he found her. Heres her sisters… Mildew got pretty bad around there. do all autos have loose buds outside?
the moms both purpled at 84 degrees. So once grown outside, its all supidly purp, almost black. The darker the get, the more the smell changed to the basement death thing. I don’t think black weed is what we wanna smoke. But it make a good breeder with the right pairing.
Check out Sirius black strain by Oregon breeders association. I bought a zip of this stuff while I was there and it was so purple almost black. No joke never seen anything like it besides some nugs called Blackie chan…crazy buds. Just about black. It was insane. Although the high wasn’t there… it had a great floral taste 
I can vouch for this strain, remember seeing it on instagram when they first dropped it and it was the darkest most purple stuff I ever saw. @Pawsfodocaws
That’s what’s up man, some crazy looking bud. Had to scoop some up .
