Trim and Time: 2 Questions

Today is day 1 of 12/12. Yahoo. I have a couple of questions for you after you peep these pics:

1. Should I trim the bottom branches for an increased yield?

2. How big do you think these guys will get, and how many days should I expect (approx) before harvest?

Thanks!

I wouldn't trim anything-a few leaves that are blocking bud sites maybe. Your plants look good. What kind of light are you using? The "stretch" won't be that much if you are using a cfl fixture than if you are using an HID fixture. Nor will your buds be that big.
