Trimming For Sea Of Green Questions

Ok...Finishing my first week of flowering. I wanted to do sea of green. Right now I have my plants in dixie cups still trying to determine sex. Hopefully I'll be left with 8 females, which will all go into 7" square pots to finish out growing.


Anyways...

When do I start trimming the lower branches?

Also...

Can I just cut them with scissors? How close do you cut them?

look up the posts on al b fuct he has this all down for ya

He just says he removes everything on the lower 1/3 of the plant in weeks 2 & 3 of flowering.

Do you have to continue trimming these? Or is this just a one time thing?
