i need some pro outdoor help with my lil purp plant.

i planted a seed last april. it germinated fine and got to like FOUR inches within 2 weeks and then it STAYED about SIX inches for seriously a fucking month or 2. so i just left it in my back yard.. and thought it was a failed mish. 2 months later i go around that part in my yard and find that the plant was like a foot tall and this was about early august.. so ever since i found the plant i've been watering it evry day at 5pm and it's about 3 feet tall and has about 2.5 - 3 grams on it.. it has alottttttt of white hairs on each lil nug and the very top has lil new leavs ready to expand and yell for me to smoke um.. but the help i need it just a couple of questions. now that you know about my plant.. :
it has been showing white hairs for about a week and everyday i go it has x2. how much longer will it be doing that. and it only has like 3 grams on it.. and its about 3 feet tall with leafs about the width of a coffe mug bottom. will it get taller and fatter? how long do i let it dry.. then how long do i let cure in a jar..
it is a reallllly danky purple chron plant i had a sack one day and found a seed.
it was really danky and potent like a 2 day old kush nug. well anyway ima show pics tomorrow but just help me out and tell me what i should do.. the main branch is about the size of a sharpy marker.. a regular one... thnx
