I'm not sure what strain they are...Once in a great while I'll find a seed in a bag of really good weed and I'll save it...i have about 20, the plants came from two of those seeds. I got lucky and both turned out to be females. I checked the plants out this morning and it looks like the hairs around the burnt ones are growing, so i hope it turns out fine. The only thing that i can think of, besides the plant having some strange ailment or insect, is that i might have bumped them with the light somehow when i was adjusting things and i didn't notice...I've never heard of ducksfoot...who knows, maybe i could have a cousin...
