Outdoor Backyard Bagseed

First outdoor grow, hopefully getting close to harvest time. This is a random bag seed, any ideas on strain, potential yield, or estimations on harvest date would be awesome. I'm not at home, so I have to pick and choose carefully when I can visit the grow, so getting the harvest date right (within reason), is essential. Any help is appreciated, thanks.

i will say sativa dominant, for the strain its an hard guess without smelling and tasting it.
Does your pistil start turning orange, red or brown ? it look to me they are still white, but the quality of the pic is kinda poor, specially with the flash..did you took the pic at night ? i would'nt flash your lady as plant are sensible to light cycle and flashes are kind of powerfull.
But anyway since it look like a sativa i will go back to check on it around the next full moon to see if it getting fatter, if the buds look fat and hard with many colorfull pistils and sparkling resin drops i will chop it a week after the full moon, i am not an expert grower but i read a lot of thread and that s what i will do if i were you . Peace
