I have my first ever plant going outside. Its three feet tall and not too impressive in size. However it is producing some nice looking buds at the moment. It showed hairs and then began budding 3 1/2 weeks ago. The seeds were from bag weed and I think it is sativa from mexico. It is hidden yet is visible and therefore I don't want to walk up to the plant with a microscope and look at the trichs. Someone might see and wonder. So, by what I'm telling you is there an average time span in which you would pick an average sativa?
