sour grape haze? how much longer?

hey RIU, this is my first grow, i found it in my front yard. it was so tiny and mal-nutritioned i nursed back to health and it has had zero problems what so ever! ha ha it is almost 6 ft. and its been about 8 weeks flowering, so far. its indica Dom, i believe. i want to know about how much longer? temps are getting pretty cold at nite. a frost is approaching, although that's not my biggest concern. a snow is coming too! shit! any ideas or comments would help? thanks (o some pistils are turning orange, i am just waiting for it to swell more. i should have a huge yield. the plant is beast) thanks for the reply's pics are on my profile under getting close
