hey.... ive got a plant doing this also, i must say this paticular plant was germ. on 07.02.06 and is already big, im at work so i have no pics. but i thought that it was just some weird "indica" strain, but i have another plant in the same pot (from the same bag) and it was a short narrow-leaf plant......
but so far, that plant is one of my best, so.....GOOD LUCK

(if i find a pic of it that i posted in another thread, ill send it)
