Hey i am considering starting growing my own lil crop but i have no experience although ive been reading alot about it. are those plants in the pictures male or female or cant u tell yet?

Which part of the plant do u cut off and smoke? is it the leaves? i thought it was only buds on the female plants. i cant see any buds in the pics or havent they developed yet?

final question....after u have harvested ur crop.....is that the plant dead or will more grow back shortly? thanx all
