LED spectrums and purple buds

[kryptonian]

Ok from what i understand about LED's is that blue is for vegetation and red is for flowering. I was just curious is in the later stages of flowering a plant develops a Purple hue are less of the lumens being absorbed? Im pretty sure i was told that plants dont use as much of the green spectrum so thats why they appear green to the human eye.



Does that make sense to anyone else, its something ive been wondering for a minute and havent seen any info on.

Good question, I do not know if the purple in the buds block some of the red. I am sure if it does it is only a small amount. As I understand the clorofil is reactive to the light spectrum. The blue feeds the clorofil during Vegitive (Clorofil A?) and during flowering the clorofil (B?) is reactive to the reds. Sorry for the misspelling... But either way I am sure not enough gets blocked by the flower to make much of a difference. Anyone ant to base their PHD on finding the differences? I dont think anything less than a clinical study will return the desired results.
Just my 2 Cents

Hey Gruetoo i appreciate the response!

just thought Id ask. I've read a lot of threads on stuff that I was surprised to learn and ended up registering because this was the site I was using as a reference.

Plants don't use as much of the human visual spectrum IIRC. Much of what is used is outside of what can be seen by the human eye. So using the human visual spectrum my not be the best way to measure what light the plant is using. So the colors of the plant will reflect those colors but the plant may not be using them anyway. I guess

first, you mean, if a plant turns purple

second, I'm sure you would be hard pressed to find factual info, but seeing many other plants are purple ( take purple basil for example ) I'm sure it's still processing the light, I grow mostly DJ so I see purple every flower, and they still grow when they turn purple, that's all I can tell you

your straining to hard, let it be what it will be, I'm sure your gonna end up happy if you have a purple plant at harvest...



for LED were still not sure on perfect spectrum.. but you can grow with red and blue LED only if you like, and you do need red in veg, and blue in flower....
