You have the scientific reason, and I just noticed it while experimenting growing methods.POTAWIE said:Purple is usually high levels of light producing anthocyanin pigments. Anthocyanins have been shown to act as a "sunscreen", protecting cells from high-light damage by absorbing blue-green light, thereby protecting the tissues from photoinhibition, or high-light stress.
Yep that's what I did, and not just one variety.POTAWIE said:It becomes very noticeable when growing the same variety of plant under different light sources.

GrumpyBear said:well i have no doubt in my mind that AJ has better lit plants then me so i think that explains it...
Omri said:Under what light source are you growing them?
I had the same type of plants, from the same source. The ones under poor winter sunlight stayed green, and the ones under bulbs turned purple.
EDIT:
GB, he sure has. the plants are getting first class care.

Well compared to the some of the others they're actually doing quite well. We have had a sunny week though, cold but sunny.Omri said:Well that explains it.
My guess is that the plants aren't very bushy, right?
Oh sweet! we're starting to get some sun as well.rainbowberry said:Well compared to the some of the others they're actually doing quite well. We have had a sunny week though, cold but sunny.
