Dry ice and roots

has anyone ever heard of uprooting a plant and laying it on a block of dry ice b4 harvesing? ive been tole if you do this it will turn the plant purple lol , i was reading about drying/curing with dry ice and forgot somebody told me about this ????anyone

I know that cold temps will turn plants purple, but have no idea why it turns them purple. I would've assumed it had to effect the foliage, directly, but IDK, maybe it's the roots that need the temp drop?

Someone has to know the biology behind it?

cold turns a plant purple because weed has more than one kind of color pigment in its leaves...
purple just happens to be the most abundant next to chlorophyll (green)
i think that the cold temperature just breaks down the chlorophyll and leaves the purple, but im not 100% sure...

some dealers put bags in their freezers to make them look more chronic...
not all purp is good purp i guess...

^That explanation/hypothesis is worth a + rep. Sounds logical, to me.

i agree lol . thanks to both for your input/comments, i will bump this thread or start a new one when i test this on one of my small plants, i am also going to try the dry ice quick dry meathod.

Sounds weird

You need the cold to affect the entire plant over at least a weeks time. Just laying it on something that is -110F isn't going to do the trick. You need whole room ambient temps under 65F to get some purple.

yes, the cold turning it puple is fact.. personally almost every outdoor grow ive done later in season (colder) they all turn purple .. it makes sense that dry ice on roots would but i was hoping to find out other side effects it has on the plants and me when i burn lol.. i will be experimenting and posting again soon.. And to No Drama, thats why im asking around , dry ice is some pretty powerfull stuff and i wouldnt be suprised if i see a change leaving a root ball on dry ice for a few hours im sure id at least see stress signs, color change or kill the plant .. will be finding out shortly

yeah it is like the trees of new england in the fall, the cold and (for the trees) amount of sunlight trigger the plant to break down the chlorophyl revealing the plant's actual color (red for maple gold for birch etc) though if it is a dry season the colors are more muted even brown I dunno how that would work for a pot plant. I would be willing though to put a plant that has the possible phenotype to produce a true purple in a refrigerator for three days & see how that works.
