your plant looks ok for a first time experience grow, its exactly what you want. you will get a nice head smoke and it should grow some while it flowers. check the faq for flowering time and when you should harvest. id say about a month 1.5 or 2, but really you dont give it a date of when you harvest its when the buds stop growing and wont grow any more. by searching grow journals on this site you should be able to find pictures of buds at harvest time. take some good pictures of some buds for us and show us how those flowers look.
whats up with not remembering the plants origin? im guessing it was aready growing when you got it but if it was a seed or clone i think id remember. i keep all my plants labled a b and c. i wish it were from clones id like to know at least one was female.
