Putting plants in a refrigerator or in a cold garage to turn them purple?

[Iron_Lion]

Has anyone ever tried putting plants in a refrigerator or in a cold garage for a few hours a day the last few days to harvest? I might try putting a few purpling plants into the cold ass garage for a few hours over the next few days to help the process along before the chop. would like 8 hours of a 40*F amient temp do the trick?

 

[P.D.S]

Does color mean that much that you? It's not like the bud gonna get any better if it's purple. But to answer your question yes cold temps will produce purpling is some varieties

 

[Agent SmokeAlot]

I'd say it's strain dependent. Some strains will purple like crazy most probably won't change.

purrple doesnt mean much to me.and I know certain plants will go purple in lower temps. Im just wondering if anyone has tried the method, of like flash purpling. theyre already turning color bud as an experiment id like to see if i can turn them in a day or 2.

Iron Lion, I would be interested to know this as well. I am just getting blue moonshine going and I may have the chance to do something like this .... although it will only get to around 50 degrees F

 

[darksith]

up here if they get hit by a light frost outdoors they purple overnight

ummm................BAG APPEAL! if it's good and it looks great it will sell like it's great. just a little assessment I've made in my time.

i just got 4 PDS girls started last night in soil. 3 going to flower one mamma and I'll be putting 30 cuts in the cloner, then aero veg then off to the ebb and grow to stink my house up!

"Bag appeal" heh ... well, to the uneducated at least. :/

It's sad really.

The reds/purples in plants, cannabis included, are simply anthocyanins.
http://en.wikipedia.org/wiki/Anthocyanin

They occur in pretty much all plants. They are not cannabinoids, and they are not psychoactive. They are what gives strains such as Blueberry and Granddaddy Purps their unique hues, and environmental factors (cold conditions in particular) are known to bring out these characteristics even more.

However, they do not contribute in any way to the traits that I personally prefer to concentrate on, such as potency, yield, flowering time, smell, and flavor ..... but if you just prefer a particular bud just because of its pretty color then that's up to you ..... each to their own I guess (i'm not a dealer, maybe that's where I'm falling down here)

 

[baet]

atleast around here, everyone loves the purps. buy em up before the green. i know it doesn't make sense.

probably like that most places where the consumer remains ignorant of the plant product. cannabis is an industry, believe it, and purple is marketing.

ironlion- anything 50 or below during night will do the trick. so to answer your question, yes, most likely. outdoors my plants usually get sum purp from the cold nights during the end of flowering.
since your strain is already purple, i guarantee the "garage purple flash", ha, will speed up the purple.

but do it, should be interesting.


good luck!

I actually came here to ask if it was indeed purpling from anthocyanins or phosphorus deficiency? Lack of phosphorus seems like a likely culprit considering it usually happens later in flowering cycle. However I would have imagined someone would have checked since that would be a relatively easy experiment to conduct.

Most plants that produce anthocyanins that I have seen start synthesizing the pigments early. But I have not seen a lot of plants so I don't know how much that is worth.

It makes perfect sense if the Purps is a good strain with good qualities (potency etc), and I'm sure it is a nice strain on many levels

But the purple hue of the bud is purely visually aesthetic, nothing more - the real qualities of the bud are coming from the cannabinoids, not the paintjob.

I know a friend who grew out a great AK47 crop. The next crop he experimented with food colorings during flowering, trying to get different colors. He was successful in turning them purple, red or any color he wanted. The sad part... he told me people came back to get more saying the purple stash was 10 times better than the stuff he was selling before... ughhh, it was the same strain from the same mom. Theres this urban legend out there that purple weed is the most amazing weed you can buy. It really is sad.

Freakin chumps.

 

[highwayman1]

agree

 

[Wasabi420]

i wouldnt put them in the cold temps myself....i would just think this would hurt the plant and make it less potent if anything. If you want purple buds why dont you just grow more purple strains. Personally some of the most unimpressive weed ive grown was purple. It looks great I wont argue, but I just think there is better stuff out there. To me a more crystally and good smelling plant is better than the purple kinds.

You eat with your eyes first. Same goes for buds.

Put ice cubes on the soil-surface or refrigerate your nutrient solution.

Getting the rootmass cold is all that's necessary to bring out the purple.

 

[Phillthy]

anyone that has to work hard to get bud to turn purple strictly for bag appeal has two problems. one, they are using the wrong genetics. two, they care too much about bag appeal.

 

[MarquisBlack]

Or-

They have a strain that purples consistently at, say 10 weeks, but would like to take it at 8.

Also, light exposure helps bring out purple. Removing major fan leaves 1 week prior to harvest will purple the lower tops.

I did it once using some ducting and a room a/c unit into a large rubbermaid. I transferred a blue apollo and a ak99 into it for the dark period everyday for three weeks towards the end, but missed the cold treatment the final week of flowering. My blue apollo which is usually a blue tint, was very purple, and my ak99 got some purple hues, but this was at a box temp of 55*. Around 50* or so would be best I think. I saw results in about three days. Not worth it IMO, purple is pretty tho.

 

[MarquisBlack]

One more tip regarding purple strains. Just because a strain shows purple while it's on the plant, does not mean that it will keep the purple hues through the curing process.

anthocyanins berry consumption have healthy effects, i bet anthocyanins bud dose too...
Richly concentrated as pigments in berries, anthocyanins were the topics of research presented at a 2007 symposium on health benefits that may result from berry consumption.[26] Laboratory-based evidence was provided for potential health effects against:

cancer
aging and neurological diseases
inflammation
diabetes
bacterial infections
Cancer research on anthocyanins is the most advanced, where black raspberry (Rubus occidentalis L.) preparations were first used to inhibit chemically induced cancer of the rat esophagus by 30-60% and of the colon by up to 80%.[26][27] Effective at both the initiation and promotion/progression stages of tumor development, black raspberries are a practical research tool and a promising therapeutic source, as they contain the richest contents of anthocyanins among native North American Rubus berries.[4]

Work on laboratory cancer models has shown that black raspberry anthocyanins inhibit promotion and progression of tumor cells by

stalling growth of pre-malignant cells
accelerating the rate of cell turnover, called apoptosis, effectively making the cancer cells die faster
reducing inflammatory mediators that initiate tumor onset
inhibiting growth of new blood vessels that nourish tumors, a process called angiogenesis
minimizing cancer-induced DNA damage.
On a molecular level, berry anthocyanins were shown to turn off genes involved with proliferation, inflammation and angiogenesis.[28][29][30], while switching on apoptosis [31], [32].

In 2007, black raspberry studies entered the next pivotal level of research – the human clinical trial – for which several approved studies are underway to examine anti-cancer effects of black raspberries and cranberries on tumors in the esophagus, prostate and colon.[33]

Anthocyanins also fluoresce; combined with their antioxidant properties this can be a powerful tool for plant cell research, allowing live cell imaging for extended periods of time without a requirement for other fluorophores [34]

if you want your plant's purple follow the 7 step's
1 Anthocyanin pigments are assembled like all other flavonoids from two different streams of chemical raw materials in the cell:
:One stream involves the shikimate pathway to produce the amino acid phenylalanine. (see phenylpropanoids)
:The other stream produces 3 molecules of malonyl-CoA, a C3 unit from a C2 unit (acetyl-CoA).[18]

2 These streams meet and are coupled together by the enzyme chalcone synthase (CHS), which forms an intermediate chalcone via a polyketide 5folding mechanism that is commonly found in plants.

3 The chalcone is subsequently isomerized by the enzyme chalcone isomerase (CHI) to the prototype pigment naringenin.

4 Naringenin is subsequently oxidized by enzymes such as flavanone hydroxylase (FHT or F3H), flavonoid 3' hydroxylase and flavonoid 3' 5'-hydroxylase.

5 These oxidation products are further reduced by the enzyme dihydroflavonol 4-reductase (DFR) to the corresponding colorless[19] leucoanthocyanidins.

6 It was believed that leucoanthocyanidins are the immediate precursors of the next enzyme, a dioxygenase referred to as anthocyanidin synthase (ANS) or leucoanthocyanidin dioxygenase (LDOX). It was recently shown however that flavan-3-ols, the products of leucoanthocyanidin reductase (LAR), are the true substrates of ANS/LDOX.

7 The resulting, unstable anthocyanidins are further coupled to sugar molecules by enzymes like UDP-3-O-glucosyl transferase to yield the final relatively stable anthocyanins.
More than five enzymes are thus required to synthesize these pigments, each working in concert. Any even minor disruption in any of the mechanism of these enzymes by either genetic or environmental factors would halt anthocyanin production.

or just find you some grape ape,purple urkle/urple and grow it no need for any hoaky trick's
