There's another forum below that just dedicated to growing.

1. It takes about 2.5-3.5 months to completely grow. But it depends on the seeds you use.
2. The amount of bud you can get ( not leaves they just give you a slight buzz, but can be used to make hash ) is entirely up to you and how much care the plant gets. Try to keep the plants in a area with sunlight most of the time without large trees blocking it. More sunlight = more bud!
