As for that plant having once been green, meh, it's a possibility but plants that were intially green, even after being exposed to cold temps, often still show green in the lower leaves when temps drop. I have to go figure out what book it was that had that plant- I want to say it was Greg Green's breeding book actually, but I may be wrong.

Purple plants may be a little MORE stealth but I'm still not gonna be planting one in my vegetable patch for damn sure.
Lol somebody was asking a question about purple haze and purple plants months ago in a forum elsewhere and a friend of mine posted this little cartoon that explained it with little cartoon photos... I was hopin Id be able to find it but no luck. I spent hours trying to find it too lol.

And yeah I guess youre right... and to the right of that plant is one that is as green as can be. Hmm I dunno then! Now Im just as curious lol.
