the blue one he tested did have noticeable color change, but also have noticeable taste change for the worse. i also saw another experiment done where they tested blue red and purple food color, the red and purple colors were far less pronounced and no taste test was given for those.

what kind of purple is that in the pix?

low 40's.... youre going to kill your plants lol....

i just abuse and beat the living shit outa mine to get em all bruised and purple looking, it works look





Jus kiddin, i feed em nut grape koolaid and food coloring, a also leave em in the fridge at night



Jus kiddin..... these were grown in 85 degree temps ... its jus geneticly purple, no bullshit additives, no cold temps, none of that mythical horseshit.

I have had some very nice "naturally purple indica strains before, and they were gorgeous, trichome-covered, knarley-lookin' plants...my only complaint was the end-size of the 100% indica upon full maturity... Itr was a mini-version of what a "perfect" plant should be, in my mind's eye... It was actually a seed I very luckily found in an eighth of Purple Kush that I had gotten, and decided to grow it out, and damned if it were'nt a female! So, there's ya'll a "bagseed" success story... I do have pics somewhere, on one of my memory cards, I keep stored away.... One of these daze, Imo get the wife to help me upload them or however she does it... I'm a part-time Ganja farmer, and a full-time industrial electrician, so I don't mess with computers all that much... Itz amazing I can do anything on here.... But, back to the point- If the temperature dips too far below about 60 or 65 degrees F, for an extended time, it retards, if not stops growth, and just like the other "legal", native foliage turns amber and all kinds of colors in the autumn and fall, so does marijuana when exposed to such conditions, only it turns purple...usually, mainly on the leaves... The purple stems that everyone thinks is soo special, are just purple, 99% of the time, because of the presence of "flowering levels" of phosphorous, during veg... Now a genetically purplr plant will exhibit purplr not only on the meristem, but on leaves, stems, petioles, and when flowered out, the calyxs and sumtimes the stigmas are also purple, and that happens even if the temp never drops below 75 or 80 degrees F... Thats when you know you have a special lil lasy, is when that occurs during flowering... Usually, the trichome-production is more profound, as well...as most of the "purps" are either 100% Indica/Afghani, or at least mostly of that descent...

I hear that if there is a large temperature difference between lights on and lights off, the stems will turn purple......

It's also in the plant's genetics, some strains will always turn purple regardless of temp difference.
