Outdoor Surprize

[PS2_MAN]

Hello, i'm not used to growing outdoors but i was venturing into my yard the other night to find my lighter after dropping it off my deck. I was searching the yard under my deck when i found a nicely growing plant that i didn't plant. I'm guessing that the seeds i throw out of my bags off the deck must have landed their and started sprouting. it must have been growing for a while, it's about 3.5-4 ft tall, bushie and it's a female!!! . What should i do, how do i know when it's going to flower or how long untill it does flower?? Any help would be greatful, and i'll try to get some pics of it up here in a couple days.

-Tnx PS2_Man
