how big does the plant have to be before i try to bud it.

my plant is about 8 inches with some nice leaves i woud like to start to flower it now while i have the room in my growspace. is it possible to bud the plant at this stage or does it need to grow more ....

yes its possible usally people like to wait for it to be around 12in

yes, it's possible. i recomend to cfl n00bs to flower at five nodes to keep things small and well lit.

however, the longer you veg, the more you yeild.
